RBT Exam Questions and Answers (2026)

B is correct. An observable, measurable definition describes a movement a second observer could see and count — pushing the worksheet off the desk qualifies, and two RBTs watching the same session would agree on whether it happened.

A is wrong because "frustrated" is a private event you infer rather than see; you cannot count frustration. C is wrong for the same reason — "dislikes" is an interpretation of a mental state, not a behavior. D is wrong because "bad attitude" is a subjective label that different observers would score differently, which is exactly what an operational definition exists to prevent.

A is correct. Rate is a count divided by the time of the observation period: 12 ÷ 40 minutes = 0.3 responses per minute. Reporting rate rather than raw count lets sessions of different lengths be compared to each other.

B is wrong because 12 is the frequency (the raw count), not the rate — it has no time unit attached. C is wrong because it describes duration, which measures how long behavior lasts, not how often it occurs. D is wrong because it inverts the calculation into an average interval between responses; that is closer to inter-response time and is not what rate means.

D is correct. Latency is the elapsed time between the onset of a stimulus — here the instruction "Time to go outside" — and the beginning of the response. It answers "how long before he starts?"

A is wrong because duration measures how long the behavior lasts once it has begun, not the delay before it starts. C is wrong because inter-response time measures the gap between the end of one response and the start of the next response, which requires two responses and no instruction. B is wrong because partial-interval recording is a discontinuous estimate of whether behavior occurred within blocks of time; it cannot produce a time-to-onset figure.

B is correct. In partial-interval recording an interval is scored if the behavior occurs at any point within it, even for one second. A behavior occurring briefly in every interval scores 100%, which overstates how much of the session it actually filled.

A is wrong — underestimation is the known bias of whole-interval recording, which requires the behavior to persist for the entire interval. C is wrong because discontinuous procedures are commonly chosen precisely for behaviors with unclear boundaries; it is continuous duration recording that needs clean onset and offset. D is wrong because interval data yields a percentage of intervals, which graphs perfectly well.

A is correct. Whole-interval recording scores an interval only when the behavior occurs throughout its entire length, so a two-second glance at the worksheet does not count. That conservative bias is exactly why it is typically paired with behaviors you are trying to increase.

B is wrong because partial-interval scores the interval for any occurrence, which would credit the brief moments the supervisor wants excluded. C is wrong because on-task behavior is continuous rather than discrete — counting "how many times" someone is on task is not meaningful. D is wrong because permanent product measures a physical outcome left behind, which does not capture whether the client was engaged throughout.

D is correct. Momentary time sampling requires the observer to look only at the designated moment — typically the end of each interval — and score whether the behavior is occurring right then. Between those moments the observer is free to do other things, which is why it suits RBTs running a group.

A is wrong because that describes partial-interval recording. B is wrong because that describes whole-interval recording. C is wrong because counting every occurrence is frequency recording, a continuous procedure that defeats the labour-saving purpose of time sampling.

A is correct. Permanent-product recording measures the lasting physical outcome the behavior produced, after the fact. The completed worksheet still exists when the session is over, so the RBT never had to watch the responses happen.

C is wrong because that is frequency recording performed in real time as the behavior occurs. B is wrong because that is duration recording, which also requires live observation. D is wrong because that is partial-interval recording, a discontinuous live-observation procedure. None of the three leaves behind a product that can be measured later.

C is correct. Total count IOA divides the smaller count by the larger count and multiplies by 100: 15 ÷ 18 = 0.833, or 83%.

B is wrong — 88% does not follow from these numbers under any standard IOA formula. A is wrong for the same reason; 94% would require the counts to be much closer together, such as 17 and 18. D is wrong because it divides the larger by the smaller (18 ÷ 15 = 120%). IOA is a measure of agreement and can never exceed 100%, so any answer above 100% signals the calculation was inverted.

D is correct. Interobserver agreement checks the measurement system, not the client. High agreement gives confidence that the numbers on the graph reflect the behavior rather than one observer's idiosyncratic scoring.

A is wrong because IOA says nothing about the client's consistency — both observers are watching the same behavior at the same moment. C is wrong because IOA increases staffing cost during those sessions rather than reducing it. B is wrong because there is no general requirement for two staff in every session; IOA is conducted periodically on a sample of sessions.

A is correct. By convention the horizontal x-axis carries the passage of time — sessions or dates — and the vertical y-axis carries the dependent variable, the behavior measure. This is what lets a reader see change over time at a glance.

B is wrong because it reverses the convention, producing a graph that no supervisor could read quickly. C is wrong because two variables cannot share one axis. D is wrong because graphing conventions in applied behavior analysis exist precisely so that graphs are interpretable without study; labelling does not make a reversed graph acceptable.

B is correct. A vertical phase-change line marks where conditions changed — baseline ending and intervention beginning, for example. Data paths are not connected across it, so the reader can compare the two conditions cleanly.

A is wrong because missing sessions are shown by a break in the data path, not a phase line. C is wrong because mastery is usually shown with a horizontal criterion line or a note, not a vertical one. D is wrong because outliers are never simply disregarded — every data point stays on the graph, and unusual sessions are explained in the notes.

B is correct. The four baseline points sit flat near 1 request per session with little bounce, and after the vertical phase-change line the points climb steadily from 4 to 16. That is a stable baseline followed by a clear increasing trend.

A is wrong because only the baseline is flat; the intervention phase rises sharply, so the description does not hold across all ten sessions. C is wrong because it reverses the direction — the values go up, not down. D is wrong because variability describes how much data bounce around; these points move in a consistent direction with very little scatter, which makes them easy rather than hard to interpret.

B is correct. Total duration is 4 + 7 + 2 = 13 minutes. As a proportion of the 60-minute session that is 13 ÷ 60 = 0.2167, or about 22%.

A is wrong because 13 is the total number of minutes, not a percentage — the conversion step was skipped. C is wrong because it appears to divide the mean episode length (about 4.3 minutes) by something, or reports mean duration as a percentage; either way it does not answer the question asked. D is wrong because it triples the correct figure, as if each of the three episodes lasted 13 minutes rather than 13 minutes in total.

B is correct. Preparing for data collection includes solving problems when materials are missing. Recording accurately in the moment on any available paper, then transferring it to the correct form the same day, preserves the integrity of the data.

A is wrong because a lost session of data creates a hole in the graph that a supervisor needs for treatment decisions; the problem was solvable. C is wrong because reconstructing data from memory produces numbers that are not real data, which is a documentation and ethics violation, not just sloppiness. D is wrong because writing one client's data on another client's form is a confidentiality and record-keeping problem even with the name crossed out.

C is correct. Inter-response time measures the interval between two consecutive responses — specifically from the end of one to the onset of the next. It describes how spread out responding is, which is why it is used alongside DRL procedures.

A is wrong because that is latency, timed from a stimulus rather than from a previous response. B is wrong because that is duration, the length of a single response. D is wrong because that is total duration across the session, a summed measure that says nothing about the gaps between responses.

D is correct. IOA only tells you something if the two observers score independently. Once one observer copies the other, high agreement is guaranteed and reveals nothing about whether the measurement system is being applied consistently.

A is wrong because speed is irrelevant to the validity problem, and copying would if anything be faster. C is wrong because both observers are authorised members of the client's team, so no confidentiality breach has occurred. B is wrong because billing depends on services delivered and documented, not on how the IOA check was conducted.

D is correct. It names specific topographies — hitting, kicking, biting — and explicitly resolves the common edge case of near-misses. Two observers reading it would score the same events the same way.

A is wrong because intent cannot be observed; observers would have to guess at what the client meant. C is wrong because "violent" is a summary label, not a description of movement, and each observer would draw the line differently. B is wrong because "losing control" is both an inference and vague about what behaviors count, which is the opposite of what an operational definition needs to do.

B is correct. Data errors are corrected through the documented correction process — which keeps an audit trail — and the supervisor is told because a wrong data point may already have influenced a treatment decision.

A is wrong because leaving known-false data in the record is a documentation violation, and the review that already happened is precisely why it must be flagged. C is wrong because silently erasing removes the audit trail that record-keeping requirements exist to preserve. D is wrong because a note beside an uncorrected point still leaves the graph showing a value the RBT knows is false.

A is correct. Frequency recording needs behaviors that are discrete — with a clear beginning and end — and of roughly uniform length, so each occurrence counts as one. Saying "help" fits both requirements.

B is wrong because continuous hand-flapping has no clean boundary between occurrences, so counting produces unreliable numbers; duration or interval recording suits it better. C is wrong because "how long" is a duration question. D is wrong because that describes momentary time sampling, a discontinuous procedure, not a count of occurrences.

D is correct. Interval-by-interval IOA divides the number of agreements by the total number of intervals (agreements plus disagreements) and multiplies by 100: 17 ÷ 20 = 0.85, or 85%.

B is wrong because 17 is the raw count of agreements, not a percentage. C is wrong because 88% would arise from a different pair of numbers, such as agreements on 15 of 17 intervals. A is wrong for the same reason — 94% would require agreement on roughly 19 of 20 intervals, which is not what the question states.

B is correct. Momentary time sampling requires the RBT to observe only at the end of each interval, freeing her attention in between — which matters when she is simultaneously responsible for safety in the community. It yields a usable estimate of how much of the outing involved conversation.

A is wrong because continuous duration recording demands unbroken attention on the stopwatch for two hours, which is incompatible with supervising safety. C is wrong because counting every utterance is even more attention-intensive and answers "how often", not "how much of the time". D is wrong because conversation leaves no physical product to measure afterward.

D is correct. Every intervention point sits below the baseline band of roughly 19–21, so the overall level has dropped — but the points swing between about 2 and 16 from session to session, which is high variability. Both features have to be reported together.

A is wrong because a decreasing trend would require the points to move consistently downward; here they zig-zag with no direction. B is wrong because the level plainly changed — no intervention point comes near the baseline band. C is wrong because it reverses the direction of the level change.

D is correct. It replaces every label with countable events: how many tasks were presented, how many were completed, and exactly what the client did on the remaining trials. Anyone reading it can picture the session.

A is wrong because "uncooperative" and "did not want to" are the same inferences as the original, just reworded. C is wrong because "rough day" and "struggled" are vaguer than what they replace. B is wrong because it adds a causal claim about sleep that the RBT did not observe — and stating an unverified cause in a clinical record is a bigger problem than the original vagueness.

D is correct. The first episode runs 4 minutes 30 seconds and the second runs 2 minutes. Total duration sums every episode: 4:30 + 2:00 = 6 minutes 30 seconds.

A is wrong because it reports only the first episode and ignores the second. C is wrong because it reports only the second episode. B is wrong because it measures from the start of the first tantrum to the end of the second, which includes the 15 minutes between them when no tantrum was occurring — that is elapsed time, not duration of behavior.

D is correct. You cannot record accurately unless you know exactly what counts as an occurrence and which procedure to use. Confirming both before the session is the core of preparing for data collection.

A is wrong because diagnosis and medication are not what determine how you score a behavior, and reviewing records beyond what your role requires raises confidentiality questions. C is wrong because scheduling is unrelated to today's data. B is wrong because family satisfaction, while important, has no bearing on how a behavior is measured.

B is correct. Interval data are reported as a percentage of intervals scored: 12 ÷ 30 = 0.40, or 40% of intervals.

A is wrong because interval procedures do not count occurrences — an interval scored does not equal one instance of behavior. C is wrong because 12 intervals of 10 seconds is 2 minutes, not 12, and interval data are an estimate rather than a true duration. D is wrong because rate requires a count of discrete responses, which whole-interval recording does not produce.

D is correct. Permanent product measures only the outcome. Twelve toys in the bin looks identical whether the client did it alone, did it with hand-over-hand prompting, or a sibling did it — the product does not record who produced it or how.

A is wrong because not needing to observe live is the procedure's main advantage, not a limitation. C is wrong because counts of products graph like any other count. B is wrong because there is no systematic direction of error; the count is accurate, it is the attribution that is uncertain.

A is correct. Data reconstructed from memory are estimates presented as measurements. A supervisor reading the graph cannot tell the difference, and may change or discontinue a program on the strength of numbers that were never recorded.

B is wrong because this is not a mere preference — accuracy and timeliness are documentation requirements. C is wrong because a colleague who was not present could not produce the data either. D is wrong because "approximately right" is not a standard that applies to clinical data; fabricated-but-plausible numbers are still fabricated.

A is correct. Latency is the time from the onset of the stimulus to the onset of the response. Timing all the way to completion combines latency with duration and yields a number that is neither.

B is wrong because the stop point is incorrect, so the measure is invalid. C is wrong because starting at response onset would eliminate the delay that latency exists to measure. D is wrong because latency is inherently a time-based measure; a count could not answer "how long before he started?"

A is correct. Low agreement is a signal that the operational definition is ambiguous or that observers were trained differently. That is the supervisor's problem to solve, and it must be solved before the data can be trusted.

B is wrong because averaging two disagreeing observers hides the problem instead of fixing it, and produces a number neither observer recorded. C is wrong because experience does not establish which observer scored correctly; the definition may be at fault. D is wrong because repeating the check without changing anything is just waiting for a chance result that clears the threshold.

C is correct. Discontinuous procedures — partial interval, whole interval, momentary time sampling — deliberately sample rather than capture everything, trading some accuracy for practicality when an RBT cannot watch continuously.

A is wrong because capturing every occurrence is the definition of continuous measurement. B is wrong because the trade-off runs the other way: continuous measurement is more accurate, and discontinuous procedures carry known directional biases. D is wrong because discontinuous procedures are used across all behavior types and are especially common with stereotypy and engagement.

D is correct. Level refers to where the data sit on the vertical axis — the typical or average value within a phase. It is one of the three standard features read from a graph.

A is wrong because direction is trend. B is wrong because session-to-session bounce is variability. C is wrong because the number of sessions is simply the phase length and is read from the x-axis, not a characteristic of the data path.

C is correct. The definition leaves the boundary undefined, so each observer supplies their own threshold. Adding a criterion — for example, "moves more than three feet beyond the doorway" — resolves it.

A is wrong because both observers saw the same event; they scored it differently, which is a definition problem rather than an attention problem. B is wrong because speed is not the issue when both observers detected the event. D is wrong because elopement is a discrete behavior that frequency recording handles well once the definition is tightened.

D is correct. The question contains two separate claims — how often (frequency) and how long each episode lasts (duration) — so both dimensions must be measured to answer it.

A is wrong because frequency and rate measure the same dimension; rate is just frequency divided by time, so the pair says nothing about episode length. C is wrong because latency measures delay to onset and IRT measures gaps between responses; neither captures how long a tantrum lasts. B is wrong because two interval procedures would both give estimates of the same dimension and neither yields a clean count.

C is correct. The honest response is to preserve the record, mark clearly which portion is affected, and let the supervisor decide whether the data are usable. That protects both the graph and the audit trail.

A is wrong because data collected under the wrong definition measure a different behavior, so mixing it in corrupts the graph. B is wrong because deleting records and concealing the error is a documentation violation regardless of intent. D is wrong because retroactively adjusting numbers to what they "would have been" is fabrication — the RBT has no way to know what the correct definition would have yielded.

A is correct. MSWO presents an array, removes the selected item, and re-presents the smaller array. The order of selection produces a ranked hierarchy of preference, which is why MSWO is so widely used before sessions.

B is wrong because paired-stimulus presents exactly two items at a time and works through every possible pair. C is wrong because with replacement the chosen item is returned to the array, so the array size never shrinks. D is wrong because free-operant involves no presentation at all — the RBT simply watches what the client engages with when everything is freely available.

C is correct. Free-operant observation requires no items to be taken away — the client has open access and the RBT records what he engages with and for how long. That avoids evoking the very behavior the question describes.

A is wrong because MSWO removes the selected item after every trial, which is exactly the situation that upsets this client. B is wrong because paired-stimulus also involves repeatedly removing items between trials. D is wrong for the same reason as A, and a larger array means more removals, not fewer.

B is correct. Satiation is an abolishing operation: it momentarily decreases the value of food as a reinforcer and therefore decreases behavior that has produced food in the past. The reinforcer has not stopped working permanently — its value has temporarily dropped.

A is wrong because an establishing operation increases reinforcer value, which is what deprivation does. C is wrong because extinction means the reinforcer is being withheld after responding; here it is still being delivered, it simply no longer motivates. D is wrong because stimulus generalization concerns responding to similar stimuli, which is unrelated to motivation.

B is correct. ABC stands for antecedent, behavior, consequence. Recording all three lets the supervisor look for patterns that suggest what is maintaining the behavior.

A is wrong because those are client characteristics, not a description of an event sequence. C is wrong because it substitutes unrelated terms for B and C; baseline and mastery criteria belong to program design, not descriptive assessment. D is wrong because a time-blocked count is a measurement procedure that captures how often the behavior happened but nothing about what surrounded it.

D is correct. The behavior reliably follows a demand and reliably produces removal of that demand. Termination of the task is negative reinforcement, which makes escape the most likely function.

A is wrong because although the RBT interacts with Talia, the consistent consequence is removal of work rather than delivery of social attention. C is wrong because no preferred item is delivered — a break is not a tangible. B is wrong because automatic reinforcement is produced by the behavior itself, independent of anyone's response; here the behavior clearly depends on what the RBT does next.

A is correct. Preferences shift, which is exactly why preference assessments are repeated. The RBT reports what she found and follows her supervisor's direction on how to use it.

B is wrong because older data do not describe what the client values today, and reinforcer effectiveness is a present-tense question. C is wrong because inventing a merged list is a clinical decision outside the RBT's role. D is wrong because re-running an assessment until it produces a desired answer is manipulating the result rather than measuring preference.

B is correct. The attention condition tests whether problem behavior is maintained by social attention. The RBT appears busy, withholds attention, and delivers a brief statement of concern only when the target behavior occurs.

A is wrong because that is the demand (escape) condition. C is wrong because free access with no demands is the control or play condition, which serves as the comparison. D is wrong because being alone with no materials is the alone condition, used to test automatic reinforcement.

A is correct. Interpreting assessment results and speaking to diagnosis or severity is outside the RBT scope of practice. Redirecting the question to the supervisor, warmly and without deflecting the parent, is the correct action.

B is wrong because an impression about diagnostic severity is a clinical interpretation an RBT is not qualified or authorised to give. C is wrong because it is false and needlessly cold — RBTs communicate with families constantly, just within their scope. D is wrong because handing over raw scores pushes the interpretation onto the parent and can cause real harm.

C is correct. Each item must appear opposite every other item exactly once. With four items that is 4 × 3 ÷ 2 = 6 unique pairs.

A is wrong because 4 is the number of items, not the number of pairings. B is wrong because 8 does not correspond to any standard pairing calculation for four items. D is wrong because 12 counts each pair twice — that is 4 × 3 without dividing by two, which would present AB and BA as separate trials.

A is correct. Going without juice for the length of the session is deprivation, an establishing operation that momentarily raises the value of juice as a reinforcer and increases behavior that has produced it.

B is wrong because juice is an unconditioned reinforcer, and in any case conditioning would not explain a within-session change in effectiveness. C is wrong because generalization concerns responding spreading to new stimuli or settings, not changes in motivation. D is wrong because schedule thinning describes requiring more responses per reinforcer, which is a procedural change nobody made here.

C is correct. Descriptive assessment observes what naturally co-occurs with the behavior. Because nothing is manipulated, it can suggest a likely function but cannot establish that a consequence is actually maintaining the behavior.

A is wrong because the natural environment is precisely where ABC data are collected — that is its advantage. B is wrong because descriptive assessment is used across behaviors of every severity. D is wrong because RBTs routinely collect ABC data under supervision; it is the interpretation that belongs to the BCBA.

B is correct. Assisting means administering the portions the supervisor assigns and recording responses faithfully. The RBT contributes accurate data; the supervisor does everything that requires clinical judgement.

A is wrong because instrument selection is a clinical decision made by the BCBA. C is wrong because interpreting results and authoring the report are supervisor responsibilities. D is wrong because goal selection follows from interpretation of the assessment, which is again outside the RBT role.

C is correct. A preference assessment identifies likely reinforcers. Something is only a reinforcer if delivering it contingently actually increases the behavior it follows — the data determine that, not the assessment.

A is wrong because "definitely" overstates it; motivating operations and satiation can undo a preference within minutes. B is wrong because the assessment says nothing about whether the item's value was learned or unlearned. D is wrong because preferences shift, which is why assessments are repeated frequently, often before each session.

D is correct. Behavior that persists when no one is available to deliver a consequence is most likely producing its own reinforcement — the sensory outcome of the behavior itself maintains it.

A is wrong because nobody is present to provide attention, so attention cannot be the maintaining consequence. B is wrong because no demands are being placed, so there is nothing to escape. C is wrong because no tangible items are available to be accessed. The defining feature of the scenario is precisely the absence of any social consequence.

C is correct. The antecedent column records what actually happened in the environment immediately before the behavior — an instruction delivered, an item removed, a peer approaching. "Bad mood" is an interpretation that another observer could not verify.

A is wrong because the entry is vague rather than overly detailed. B is wrong because the antecedent and consequence columns are distinct by design. D is wrong because moving an unobservable inference to a different column does not make it observable; the fix is to describe what was seen.

D is correct. In a free-operant assessment the client has open access to an array and the RBT records duration of engagement with each item. Longer engagement suggests higher preference.

A is wrong because first selection from a pair describes the paired-stimulus format. C is wrong because trials-to-criterion is a teaching measure, not a preference measure. B is wrong because free-operant does not involve offering items one at a time, so refusal is not the unit being recorded.

B is correct. Assessments are administered as designed so results are comparable and interpretable. The RBT's observation is genuinely useful — she reports it, and the supervisor decides what it means.

A is wrong because skipping items without authorisation creates a gap the supervisor cannot interpret. C is wrong because prompting during an assessment measures prompted performance instead of independent skill, which invalidates the item. D is wrong because substituting items changes what the assessment measures and is a clinical decision outside the RBT role.

C is correct. Skipping breakfast is food deprivation — an establishing operation that raises the momentary value of crackers and increases behavior that produces them. That is the definition of an MO in action.

A is wrong because differential responding to red versus blue is stimulus control from discrimination training. B is wrong because responding dropping when reinforcement stops is extinction, a consequence-based effect. D is wrong because performing across a new therapist is generalization. Only B involves a change in how valuable a consequence is.

B is correct. Descriptive assessment depends on catching the behavior as it happens. When the behavior is rare, the RBT may observe for weeks before enough instances accumulate to suggest a pattern.

A is wrong because ABC data are routinely collected on aggression. C is wrong because there is no such fixed threshold. D is wrong because the choice of assessment method is the supervisor's decision and depends on many factors; a functional analysis of dangerous behavior carries its own risks and requirements.

B is correct. MSWO requires one selection per trial to produce a valid ranking. Blocking the extra reach and re-presenting keeps the procedure intact and yields a scorable trial.

A is wrong because two simultaneous selections break the ranking logic the procedure depends on. C is wrong because recording a choice the client did not make substitutes the RBT's guess for data. D is wrong because a single ambiguous trial is a routine, easily corrected event, not a reason to abandon the assessment.

A is correct. The behavior occurs specifically when a preferred item is removed and reliably results in the item being returned. Access to the tangible is the maintaining consequence.

B is wrong because the screaming does not occur during work demands, which is the opposite of what an escape function would predict. C is wrong because although a peer is involved, the consistent outcome is return of the tablet rather than social attention. D is wrong because the behavior depends entirely on what the peer does next, so it is socially mediated rather than automatically reinforced.

C is correct. The RBT's contribution to assessment is accurate, faithful data collection under the supervisor's direction. That contribution is essential, but it stops short of interpretation.

A is wrong because designing and interpreting assessments requires the analytic training a BCBA has. B is wrong because determining function is exactly the interpretive step reserved for the supervisor. D is wrong because deciding the assessment is complete is a clinical judgement based on interpreting the data so far.

C is correct. Reinforcer value is momentary. A client who is satiated on an item, or newly deprived of another, will respond very differently — so a fresh assessment keeps teaching sessions effective.

A is wrong because although choice is a genuine benefit, it is not the reason the assessment's timing matters. B is wrong because the BACB sets no such rule; assessment frequency is a clinical decision. D is wrong because running assessments more often increases the data the RBT collects, not decreases it.

A is correct. Functional analysis protocols include predefined safety and termination criteria precisely because behavior can escalate. Following them and alerting the BCBA is both the safe and the procedurally correct action.

B is wrong because client safety always outranks data integrity; no analysis is worth an injury. C is wrong because changing conditions on her own initiative is a clinical decision outside her role, and it contaminates the analysis. D is wrong because it abandons the protocol rather than following the escalation procedure the protocol already specifies.

D is correct. A discrete trial begins with the discriminative stimulus, may include a prompt, then the client's response, then the programmed consequence, then a brief inter-trial interval that separates one trial from the next.

A is wrong because the response cannot precede the instruction that occasions it. C is wrong because a prompt supports responding to an SD that has not yet been delivered, and a consequence cannot precede the response it follows. B is wrong for the same reason — consequences by definition come after the response.

B is correct. Most-to-least starts with the most intrusive prompt that guarantees a correct response, then systematically reduces intrusiveness. It is typically chosen for brand-new skills because it minimises errors from the start.

A is wrong because least-to-most runs in the opposite direction, beginning with the least intrusive prompt and adding help only after an error. C is wrong because constant time delay inserts a fixed pause before prompting rather than changing prompt type. D is wrong because progressive time delay gradually lengthens that pause; neither delay procedure describes moving through a prompt hierarchy.

C is correct. Backward chaining teaches the final step first, so the client always experiences completing the chain and contacting the natural reinforcer immediately.

A is wrong because forward chaining teaches step one first and adds steps in order. B is wrong because total-task chaining has the client attempt every step in every session with prompting as needed. D is wrong because shaping reinforces successive approximations toward a single behavior rather than teaching a sequence of distinct steps.

B is correct. A task analysis breaks a multi-step skill — brushing teeth, making a sandwich — into a sequence of discrete, observable steps that can each be taught and measured.

A is wrong because that is a duration measure, not a breakdown of the skill. C is wrong because task preference is what a preference assessment addresses. D is wrong because a count of independent completions is data produced from a task analysis, not the task analysis itself.

C is correct. Shaping is differential reinforcement of successive approximations: reinforcement is delivered for responses progressively closer to the target, and earlier approximations stop being reinforced.

A is wrong because chaining links separate behaviors into a sequence; "ball" is one response, not a chain. B is wrong because fading gradually changes a stimulus or prompt, whereas here the response requirement is what changes. D is wrong because discrimination training establishes responding under one stimulus and not another, which is not what is happening.

C is correct. A fixed-ratio schedule delivers reinforcement after a set number of responses. Every third response means FR 3.

A is wrong because fixed-interval schedules are time-based — FI 3 would reinforce the first response after three minutes have elapsed. B is wrong because variable-ratio reinforces after an average number of responses that varies from one delivery to the next. D is wrong because variable-interval is also time-based, reinforcing the first response after an average amount of time.

D is correct. Variable-ratio schedules reinforce after an unpredictable number of responses, so there is no signal that reinforcement is unavailable. That produces high, steady responding that persists well when reinforcement stops.

A is wrong because fixed-ratio schedules produce a characteristic post-reinforcement pause after each delivery. C is wrong because fixed-interval produces a scalloped pattern — little responding early in the interval, a burst near the end. B is wrong because continuous reinforcement builds new behavior efficiently but extinguishes fastest, since the absence of reinforcement is immediately obvious.

A is correct. The teaching opportunity arose from the client's own motivation, occurred in the natural flow of activity, and produced the natural reinforcer — the bubbles themselves. That is naturalistic teaching.

B is wrong because discrete-trial teaching is adult-led, uses massed structured trials and typically arbitrary reinforcers. C is wrong because no multi-step chain is being taught. D is wrong because although some discrimination is involved, the defining feature here is capturing the client's motivation in the moment, not teaching responding to one stimulus over another.

D is correct. Error correction re-presents the trial with enough prompting to produce a correct response, so the client practises the correct response rather than rehearsing the error.

A is wrong because reinforcing an incorrect response strengthens exactly what you are trying to weaken. B is wrong because a bare reprimand teaches nothing and leaves the error as the last thing practised. C is wrong because a single error is an ordinary part of teaching, not a reason to stop the session.

B is correct. The skill is under narrow stimulus control — it occurs with one person in one setting. Generalization across people, settings and materials has to be programmed deliberately; it rarely happens by itself.

A is wrong because he demonstrates the skill reliably at the table, so acquisition clearly occurred. C is wrong because reinforcer choice might contribute but does not explain the setting-specific pattern. D is wrong because attributing it to non-compliance is an inference that ignores the more parsimonious and testable explanation.

B is correct. Multiple-exemplar training deliberately varies the stimuli present during teaching, which prevents the response from coming under the control of one narrow set of conditions.

A is wrong because more trials in identical conditions strengthens the skill but narrows stimulus control further, making generalization less likely. C is wrong because a bigger reinforcer affects motivation, not the range of conditions under which the skill occurs. D is wrong because continuous reinforcement is useful for acquisition but reduces maintenance and does not address generalization at all.

C is correct. Something aversive — the demand — is removed contingent on the response, and the response increases in the future. Removal plus an increase in behavior is negative reinforcement.

A is wrong because adding a sticker is positive reinforcement; something is presented, not removed. B is wrong because removing screen time to decrease hitting is negative punishment. D is wrong because adding a reprimand to decrease grabbing is positive punishment. The word "negative" refers to removal, never to something unpleasant.

A is correct. Reinforcing responding in the presence of one stimulus while withholding it in the presence of another establishes differential responding — the red card becomes the SD and the blue card the S-delta.

B is wrong because response generalization describes varied responses to the same stimulus, not differential responding across stimuli. C is wrong because a single touch response is not a chain. D is wrong because stimulus fading gradually alters a stimulus dimension to transfer control; nothing is being gradually altered here.

D is correct. A skill acquisition plan must tell any qualified RBT exactly what to teach, how to teach it, how to prompt and fade, what to reinforce and when the skill counts as mastered.

A is wrong because billing information is administrative and belongs elsewhere in the record. C is wrong because although medical information matters for safety, allergies alone do not tell you how to teach a skill. B is wrong because supervision logs document staff oversight, not client programming.

A is correct. When prompts are delivered reliably and not faded, the prompt itself becomes the discriminative stimulus. The client learns that waiting produces help, so independent responding drops away.

B is wrong because satiation would reduce responding generally, not produce this specific pattern of waiting for a prompt. C is wrong because generalization means the skill spreads to new conditions, which is the opposite of what is described. D is wrong because an extinction burst is a temporary increase in behavior when reinforcement is withheld — nothing is being withheld here.

A is correct. A mand is a request. It is under the control of a motivating operation — wanting the cookie — and is reinforced by receiving the specific thing requested.

B is wrong because naming something present is a tact, controlled by the non-verbal stimulus and reinforced socially. C is wrong because repeating what was just said is an echoic, controlled by a vocal-verbal stimulus with point-to-point correspondence. D is wrong because answering a question without receiving the item is an intraverbal.

B is correct. An intraverbal is verbal behavior controlled by someone else's verbal behavior, without point-to-point correspondence — conversation, answering questions, filling in blanks. Nothing is present to name and nothing is being requested.

A is wrong because he is not asking for anything and no motivating operation is driving the response. D is wrong because a tact requires the item or event to be present to be labelled; there are no shoes in view. C is wrong because an echoic repeats the speaker's words, and "shoes" does not match "what do you wear on your feet?"

D is correct. Preparing materials, datasheets and reinforcers in advance means teaching time is spent teaching rather than searching, and it is what the task explicitly requires.

A is wrong because diagnostic history does not change how a plan is run and is not the RBT's to review at will. C is wrong because family communication is valuable but not session preparation. B is wrong because target selection is a clinical decision made by the supervisor and specified in the plan.

A is correct. A token has no value on its own — it becomes reinforcing through its learned pairing with other reinforcers it can be exchanged for. That learning history is what makes it conditioned.

C is wrong because water is an unconditioned reinforcer; nobody has to learn to value it. B is wrong for the same reason — food's reinforcing value is biological. D is wrong because sleep is likewise unconditioned and requires no learning history to function as a reinforcer.

A is correct. Total-task chaining runs the whole sequence every time, with prompting on whichever steps the client cannot yet do independently. It suits learners who can already perform several steps.

B is wrong because teaching step one to mastery first describes forward chaining. C is wrong because starting with the final step describes backward chaining. D is wrong because a chain's steps occur in a fixed functional order — you cannot dry your hands before turning on the tap.

D is correct. Constant time delay inserts a fixed interval between the SD and the prompt on every trial, giving the client a consistent window to respond independently before help arrives.

A is wrong because progressive time delay lengthens the interval over successive trials — 1 second, then 2, then 3. C is wrong because most-to-least changes the intrusiveness of the prompt rather than its timing. B is wrong because graduated guidance involves physically shadowing the client and adjusting pressure moment to moment.

D is correct. The brief pause marks the end of one trial and the start of the next, so responses can be attributed to a specific SD and the trials remain genuinely discrete.

A is wrong because the interval is a boundary marker of a couple of seconds, not a reinforcement break. C is wrong because although data recording often happens then, that is a practical convenience rather than the procedural purpose. B is wrong because thinning a schedule is a separate procedure that changes how often reinforcement is delivered.

C is correct. Schedule thinning gradually requires more responding per reinforcer, which builds persistence and moves the client toward the leaner reinforcement available in everyday environments.

A is wrong because the goal is durable responding, not difficulty for its own sake. B is wrong because thinning is designed to maintain responding, not reduce motivation — thinning too fast is precisely the error to avoid. D is wrong because an extinction burst is an unwanted side effect of withholding reinforcement entirely, not a goal.

C is correct. Maintenance is the continued performance of a skill after teaching has ended. The skill was acquired and then lost, which is a maintenance failure — usually because reinforcement stopped entirely rather than thinning to a natural level.

A is wrong because acquisition clearly succeeded three months ago. B is wrong because nothing indicates the client is confusing water with another stimulus. D is wrong because prompting concerns how the skill was originally taught, not why it faded afterward.

C is correct. A gestural prompt — pointing or glancing toward the correct item — provides the least assistance and involves no contact and no demonstration, making it the least intrusive of the four.

A is wrong because full physical guidance is the most intrusive prompt available. B is wrong because partial physical still involves touching the client, making it more intrusive than a gesture. D is wrong because a model requires the RBT to demonstrate the whole response, which provides more information than a gesture.

B is correct. Requiring performance with more than one instructor means the skill cannot be counted as mastered while it works with only one person. Generalization is written into the definition of mastery rather than left to chance.

A is wrong because involving a second instructor increases coordination work, not reduces it. C is wrong because supervision requirements govern oversight of the RBT, not mastery criteria for a client's skill. D is wrong because the point is durability across conditions, not difficulty.

B is correct. The RBT's gaze is functioning as an inadvertent prompt. The client is responding to her eyes rather than to the SD, so the data overstate independent performance.

A is wrong because true mastery requires responding under the SD alone; remove the gaze and responding would likely collapse. C is wrong because generalization means performing across new conditions, not depending on a subtle cue. D is wrong because schedule density is unrelated to which stimulus is controlling the response.

A is correct. Shaping is the procedure of choice when the terminal behavior is not yet in the client's repertoire at all — you reinforce whatever rough approximation exists and gradually raise the requirement.

B is wrong because a response the client can already perform calls for prompting and prompt fading, not shaping. C is wrong because a setting-limited skill is a generalization problem. D is wrong because response speed is addressed by changing the reinforcement criterion for latency or fluency, not by shaping a new topography.

A is correct. An S-delta signals that reinforcement is not available for the response. Over time the client responds less in its presence, which is one half of a discrimination.

B is wrong because that describes the SD, the discriminative stimulus. C is wrong because prompts are supplementary cues used to occasion correct responding, not a stimulus class defined by reinforcement history. D is wrong because the reinforcer is a consequence, whereas both SD and S-delta are antecedents.

A is correct. Because teaching happens inside the natural activity with natural reinforcers, the conditions during teaching resemble the conditions where the skill must eventually occur — which makes generalization far more likely.

B is wrong because DTT produces many more trials per minute; that density is DTT's advantage. C is wrong because data are collected in every teaching format. D is wrong because naturalistic teaching very much uses reinforcement — it simply uses the natural consequence rather than an arbitrary one.

D is correct. Reinforcing every correct response makes the contingency unmistakable, which is why continuous reinforcement produces the fastest acquisition of a brand-new skill.

A is wrong because continuous reinforcement produces the least resistance to extinction — that is why the schedule is later thinned. C is wrong because natural environments reinforce intermittently and unpredictably. B is wrong because reinforcing every response makes satiation more likely, not less, especially with edible reinforcers.

D is correct. In forward chaining, the step currently being taught is reinforced when performed to criterion, and the rest of the chain is completed with assistance so the client still experiences the whole sequence and its natural outcome.

B is wrong because stopping mid-chain leaves the teeth half-brushed and breaks the functional sequence. C is wrong because switching procedures is a clinical decision for the supervisor, not the RBT. A is wrong because requiring full independence before any reinforcement means the client is never reinforced, which is the failure chaining exists to prevent.

C is correct. Prompts are temporary supports. Transfer of stimulus control means the natural SD alone eventually evokes the response, and the prompt is no longer needed.

B is wrong because transferring across instructors is generalization across people. A is wrong because moving across settings is generalization across settings. D is wrong because changing reinforcer type is reinforcer fading or pairing — a consequence-side change, whereas stimulus control concerns antecedents.

C is correct. A single, clear instruction followed by the programmed wait gives the client a defined opportunity to respond and keeps the trial discrete and scorable.

A is wrong because repeating the SD teaches the client to wait for the second or third delivery before responding. B is wrong because attending is a prerequisite; an SD delivered to a client who is not attending is not a valid trial. D is wrong because varying wording within acquisition trials introduces uncontrolled variability — generalization is programmed deliberately once the skill is established.

B is correct. Reinforcement is defined by its effect on behavior. If delivering the item contingently does not increase the behavior it follows, it is not functioning as a reinforcer regardless of how much the client seems to like it.

A and D are wrong because preference assessments identify likely reinforcers; the effect on behavior still has to be verified. C is wrong because emotional reactions are not the criterion — many clients show little visible reaction to items that strongly reinforce their behavior.

A is correct. Putting a desired item in sight but out of reach creates a motivating operation — the client wants it and cannot get it alone — which is exactly the condition under which a mand is likely to occur.

B is wrong because free access removes any need to request. C is wrong because with nothing desirable present there is no motivation to mand at all. D is wrong because instructing the client to ask makes the response a prompted compliance rather than a mand under motivational control.

D is correct. Response generalization is the emergence of different but functionally equivalent responses — "hi" and waving were never taught, yet they serve the same purpose as the taught greeting.

A is wrong because greeting a new person is stimulus generalization across people. C is wrong because labelling across contexts is stimulus generalization across settings and materials. B is wrong because performance over time is maintenance, not generalization.

C is correct. Implementing the plan with fidelity is the RBT's core responsibility, and her clinical observation is genuinely valuable — delivered to the supervisor, who is authorised to modify the plan.

A is wrong because even a one-session trial is an unauthorised protocol change that contaminates the data. B is wrong because documenting an unauthorised change does not make it authorised. D is wrong because parents are essential partners but do not authorise changes to clinical protocols; that is the supervisor's role.

D is correct. Shaping works by raising the criterion in increments the client can actually meet. Jumping from 20 seconds to 3 minutes means reinforcement becomes unavailable, and the behavior deteriorates rather than improving.

A is wrong because there is no mechanism by which an unreachable requirement produces the target performance. C is wrong because generalization is unrelated to how steeply a shaping criterion is raised. B is wrong because stimulus control concerns which antecedent evokes the response, not the size of the shaping step.

D is correct. The client is responding to an irrelevant dimension. Once size is equalised, the discrimination collapses — showing the target feature was never controlling the response.

A is wrong because mastery would mean correct responding regardless of size. C is wrong because a stronger reinforcer increases motivation but cannot teach which feature to attend to. B is wrong because generalization would mean responding correctly to new examples, whereas here responding fails as soon as an irrelevant cue is removed.

D is correct. A token has no intrinsic value. Its reinforcing power comes entirely from being reliably exchangeable for back-up reinforcers the client actually wants — which is what makes it a conditioned reinforcer.

A is wrong because nothing about a plastic chip is naturally reinforcing. C is wrong because response cost is a separate procedure that must be specified in the plan, not the source of a token's value. B is wrong because ease of delivery is a practical convenience, not the mechanism of effectiveness.

C is correct. Mastery decisions are made from the prompt-level data. Recording prompted responses as independent inflates the numbers and can retire a skill from active teaching while the client still cannot perform it alone.

A is wrong because the error may prevent mastery from ever occurring, and it corrupts the record either way. B is wrong because prompt dependence is caused by how prompts are faded, not by how they are recorded. D is wrong because scoring errors do not change the schedule specified in the plan.

C is correct. Periodic probes catch a skill that is starting to drift, and intermittent reinforcement keeps it worthwhile without requiring the dense schedule used during acquisition.

A is wrong because removing reinforcement entirely is functionally extinction, which is the most common cause of maintenance failure. B is wrong because returning to continuous reinforcement is a step backward and makes the skill less durable. D is wrong because re-teaching from scratch wastes teaching time that could be spent on new targets.

A is correct. A tact is labelling something present in the environment, under the control of that non-verbal stimulus, and it is typically reinforced socially — here by the RBT's acknowledgement.

B is wrong because the client is not requesting the plane and receives no item. C is wrong because an intraverbal is occasioned by someone else's verbal behavior, and nobody spoke first. D is wrong because an echoic repeats what a speaker just said, and there was no prior vocal model.

A is correct. The preference hierarchy exists exactly for this situation. Using the next identified item keeps teaching effective, and telling the supervisor keeps the record accurate and lets her adjust if needed.

B is wrong because teaching without reinforcement removes the mechanism that makes acquisition work. C is wrong because cancelling costs the client a session over a solvable problem. D is wrong because a free choice from anywhere in the clinic bypasses the assessed hierarchy and may introduce items that are not approved.

A is correct. If the correct card is always in the same place, the client can be reinforced for a position response without ever attending to the stimulus. Randomising placement forces the discrimination onto the intended feature.

B is wrong because consistent placement is exactly what creates the position bias. C is wrong because a single card removes the discrimination entirely — with nothing to choose between, correct responding is meaningless. D is wrong because a bigger reinforcer strengthens whatever response is occurring, including the position response.

A is correct. An extinction burst is a temporary increase in the frequency, intensity or duration of behavior immediately after the maintaining reinforcer is withheld. It is expected, and it typically subsides if the procedure is applied consistently.

B is wrong because stopping during a burst reinforces the escalated behavior at its worst, making it far harder to treat later. C is wrong because spontaneous recovery is the reappearance of a behavior after it has already decreased, not the initial spike. D is wrong because nothing indicates a new consequence is now maintaining the behavior.

C is correct. DRO — differential reinforcement of other behavior — reinforces the absence of the target behavior for a specified period. If hand-biting occurs, the interval typically resets and no reinforcer is delivered.

A is wrong because delivering reinforcement regardless of behavior is non-contingent reinforcement, a different procedure. B is wrong because reinforcing a specific appropriate alternative is DRA. D is wrong because reinforcing a reduced rate is DRL, which tolerates some occurrences rather than requiring none.

A is correct. Differential reinforcement of alternative behavior reinforces a specific replacement response that produces the same reinforcer as the problem behavior — attention, in this case — while the problem behavior no longer produces it.

B is wrong because DRO reinforces the absence of behavior rather than a specific alternative. C is wrong because DRL reinforces a lower rate of the problem behavior itself. D is wrong because response cost involves removing a reinforcer contingent on the problem behavior, which is not described here.

C is correct. DRI — differential reinforcement of incompatible behavior — reinforces a response that cannot physically co-occur with the problem behavior, such as reinforcing hands-in-lap to reduce hand-flapping.

A is wrong because DRO reinforces any period without the behavior, with no requirement that anything specific occur. B is wrong because DRA's alternative merely serves the same function; it need not be physically incompatible. D is wrong because DRL reinforces a reduced rate of the target behavior itself rather than a competing response.

C is correct. Non-contingent reinforcement delivers the maintaining reinforcer on a fixed time schedule regardless of behavior. This abolishes the motivating operation for the problem behavior — the client no longer has to act out to get attention.

B is wrong because DRO requires the absence of the behavior before delivering the reinforcer; NCR has no such contingency. A is wrong because extinction withholds the reinforcer rather than providing it freely. D is wrong because a high-p sequence involves presenting easy requests before a difficult one.

A is correct. A high-probability request sequence delivers several instructions with a strong compliance history immediately before a low-probability request, increasing the likelihood of compliance with the hard one.

B is wrong because errorless learning uses prompting to prevent errors during skill teaching, not to increase compliance. C is wrong because shaping reinforces successive approximations toward a new response, and clapping is not an approximation of writing. D is wrong because response cost removes a reinforcer following problem behavior, which has not occurred.

C is correct. Extinction always means withholding the maintaining reinforcer. For escape-maintained behavior, the reinforcer is removal of the demand — so extinction means the demand stays in place and the behavior no longer buys a break.

A is wrong because ignoring is extinction for attention-maintained behavior; ignoring an escape-maintained tantrum while removing the task actually reinforces it. B is wrong because removing the demand delivers exactly the reinforcer being targeted. D is wrong because withholding tangibles addresses a function that is not operating here.

A is correct. Spontaneous recovery is the reappearance of a previously extinguished behavior after a period without it. If the extinction procedure remains in place, it typically fades again quickly.

B is wrong because an extinction burst occurs immediately after extinction begins, not weeks into a successful reduction. C is wrong because response generalization concerns new forms of a reinforced response, not the return of a reduced one. D is wrong because satiation is a motivational change that reduces reinforcer value, which does not explain a behavior returning.

D is correct. A behavior reduction plan has to tell any RBT what the behavior looks like, what maintains it, what to change beforehand, what to teach instead and how to respond when it occurs.

A is wrong because educational history is background information, not procedural instruction. C is wrong because staffing records are administrative. B is wrong because scheduling preferences are logistical and appear nowhere in a clinical protocol.

D is correct. Problem behavior is doing a job — getting attention, escaping a demand, obtaining an item. Suppressing it without teaching a functional alternative leaves the need unmet, and the behavior usually returns or is replaced by something worse.

A is wrong because it treats a clinical necessity as paperwork. C is wrong because it describes a side benefit rather than the reason. B is wrong because no blanket prohibition exists; the reason is clinical effectiveness and client welfare.

C is correct. DRL — differential reinforcement of low rates — reinforces the behavior when it occurs at or below a specified rate. It suits behaviors that are acceptable in moderation but problematic in excess.

A is wrong because DRO would require zero occurrences, and hand-raising is a behavior you want to keep at a lower level rather than eliminate. B is wrong because no alternative response is being taught. D is wrong because no physically incompatible behavior is being reinforced.

D is correct. Offering choice happens before the behavior and changes the conditions under which work is presented — that is the defining feature of an antecedent intervention.

A is wrong because praise delivered after a response is a consequence procedure. C is wrong because removing a token following shouting is response cost, also a consequence. B is wrong because withholding attention after screaming is extinction, which by definition operates on what follows the behavior.

B is correct. Safety comes first, and the written crisis plan specifies exactly what to do — which typically starts with clearing the area and protecting people rather than continuing programming.

A is wrong because concern about reinforcement never outweighs immediate physical danger. C is wrong because restraint may be prohibited, requires specific training and authorisation, and is never a default first response. D is wrong because calling the parent, while it may follow, does nothing to address the immediate hazard.

B is correct. Extinction removes access to the reinforcer without providing another route to it. Pairing it with DRA or FCT gives the client an appropriate way to get what they need, which reduces bursts and produces more durable change.

A is wrong because speed is not the central concern; effectiveness and welfare are. C is wrong because RBTs implement extinction routinely under supervision without the BCBA physically present. D is wrong because extinction applies to every function once the maintaining reinforcer is identified.

B is correct. FCT teaches a communicative response that produces the same reinforcer as the problem behavior — here, escape — while the problem behavior is placed on extinction. It is a specific and very common form of DRA.

A is wrong because nothing is being removed following the behavior. C is wrong because non-contingent escape delivers breaks on a schedule regardless of what the client does. D is wrong because although discrimination is involved, the defining feature is teaching a functional communication response.

B is correct. Function is about what maintains behavior, not what it looks like. Identical topographies can be maintained by entirely different consequences, which is why interventions must follow assessment rather than appearance.

A is wrong because although behavior can be multiply maintained, the scenario describes two clients with one function each. C is wrong because self-injury is routinely assessed and its function identified. D is wrong because it states the opposite of the point — topography tells you nothing reliable about function.

A is correct. The motivating operation is the aversiveness of long work. Shortening intervals and scheduling breaks reduces that aversiveness directly, so escape becomes less valuable and the behavior less likely.

B is wrong because a snack addresses food motivation, which is not what maintains this behavior. C is wrong because praise is a consequence procedure, not an antecedent one. D is wrong because response cost is also a consequence, and it does nothing about why the work is aversive.

B is correct. Modifying a behavior plan is a clinical decision reserved for the supervisor. Acknowledging the parent's concern and routing it to the BCBA respects both the family and the scope of the RBT role.

A is wrong because parental consent to treatment is not the same as authority to alter a clinical protocol. C is wrong because it dismisses a legitimate concern the supervisor needs to hear. D is wrong because an unauthorised trial is a fidelity breach regardless of how it is reported afterward.

B is correct. Behavior is commonly described as maintained by social attention, escape or avoidance, access to tangibles, or automatic reinforcement produced by the behavior itself.

A is wrong because positive and negative describe whether a stimulus is added or removed, not what maintains behavior. C is wrong because ABC names the three-term contingency, a recording framework rather than a list of functions. D is wrong because those are categories of behavior type, not functions.

B is correct. DRO reinforces the absence of the behavior across the whole interval. An occurrence means the criterion was not met, so no reinforcer is delivered and the interval restarts.

A is wrong because delivering the reinforcer would follow an occurrence of the very behavior being reduced. C is wrong because doubling the interval is a plan change the RBT is not authorised to make. D is wrong because reinforcing immediately after the behavior directly strengthens it.

C is correct. Incidents require prompt, objective documentation on the form the agency specifies, describing what was observed rather than what the RBT concluded.

A is wrong because reporting requirements are triggered by the incident, not only by injury. B is wrong because waiting to be asked delays reporting and degrades the accuracy of the account. D is wrong because a routine session note does not satisfy incident-reporting requirements, which usually route to different people.

C is correct. Occasionally giving in places the behavior on an intermittent reinforcement schedule, which produces the most persistent responding of all. Inconsistent extinction makes the problem substantially worse than not starting.

A is wrong because the behavior typically strengthens rather than gradually decreasing. B is wrong because the same reinforcer is still maintaining it; only the schedule has changed. D is wrong because the effect is large and in the wrong direction.

D is correct. Priming prepares the client for what is coming before the event occurs, reducing the uncertainty that often occasions problem behavior at transitions.

B is wrong because praise after the transition is a consequence procedure. C is wrong because removing an item following behavior is response cost, also a consequence. A is wrong because timing transitions is measurement, not intervention.

C is correct. Practising within one's scope of competence means not implementing procedures you have not been trained on. Raising it with the supervisor gets the training arranged and protects the client.

A is wrong because improvising a behavior reduction procedure risks harm and produces useless data. B is wrong because informal peer instruction during a live session is not competency-based training and the peer is not the authorising supervisor. D is wrong because silently omitting part of a plan is a fidelity breach the supervisor cannot see in the data.

B is correct. If the alternative takes more effort or works less reliably than the problem behavior, the client has no reason to use it. Matching the reinforcer and making the alternative efficient is what makes DRA effective.

A is wrong because physical incompatibility is required for DRI, not DRA. C is wrong because alternatives are frequently gestures, cards or device responses. D is wrong because DRA very often involves teaching the alternative from scratch.

A is correct. Multiply maintained behavior serves different functions in different contexts — escaping demands at school, gaining attention at home. Effective plans then need distinct procedures for each context.

B is wrong because response generalization concerns varied response forms, not varied maintaining consequences. C is wrong because automatic reinforcement is one specific function, and the scenario involves several. D is wrong because behavioral contrast describes behavior changing in one setting when contingencies change in another.

D is correct. Restrictive and physical procedures carry real risk and are tightly governed. Only techniques written into this client's plan, for which the RBT holds current training, may be used.

A is wrong because the objection is about authorisation and safety, not effectiveness. C is wrong because consent for restrictive procedures is obtained through the treatment planning process, not asked for mid-crisis. B is wrong because a good outcome does not retroactively authorise an unapproved restrictive procedure.

A is correct. A warning and a visual timer make the transition predictable and signal the end of access in advance, which reduces the abruptness that occasions the behavior. It is an antecedent change addressing the situation directly.

B is wrong because ignoring is a consequence procedure and does not address the transition itself. C is wrong because removing all preferred items is restrictive and harms the client's quality of life. D is wrong because making the next task harder increases aversiveness and would likely worsen the behavior.

C is correct. An extinction burst is the temporary spike in the behavior right after the maintaining reinforcer is withheld. Sessions 5 and 6 jump well above the baseline band before the decline begins — the classic burst pattern.

A is wrong because a stable baseline is the pre-intervention comparison, not an effect of extinction. B is wrong because the decline is the intended therapeutic effect that follows the burst. D is wrong because the final low point shows the procedure worked, not the burst itself.

B is correct. A replacement behavior must produce the same reinforcer as the problem behavior. Screaming produces escape, so requesting a break is the functionally matched alternative.

A is wrong because requesting a toy produces a tangible, which is not what maintains the screaming. C is wrong because raising a hand produces attention, again the wrong function. D is wrong because sitting quietly is a goal rather than a replacement — it gives the client no way to communicate his need to escape.

B is correct. For attention-maintained behavior, any substantial social response — including a reprimand or explanation — functions as the reinforcer. Well-intentioned lecturing strengthens exactly what it is meant to reduce.

A is wrong because complexity is a secondary issue; even a simple explanation would reinforce. C is wrong because time cost is trivial compared with strengthening aggression. D is wrong because who delivers the attention does not change its reinforcing effect.

B is correct. By changing the conditions that occasion behavior, antecedent strategies reduce the number of occurrences in the first place — which is safer for the client and everyone around them.

A is wrong because implementation speed varies and some antecedent strategies require substantial environmental change. C is wrong because every procedure in a behavior plan requires data. D is wrong because all procedures are implemented under supervision regardless of type.

B is correct. The visitor's reaction is delivering the reinforcer the procedure is withholding, so the extinction is not actually in effect. Addressing it discreetly, or escalating to the supervisor, protects the procedure.

A is wrong because ignoring it means the behavior is being intermittently reinforced, which makes it more persistent. C is wrong because a solvable environmental problem does not warrant abandoning the plan. D is wrong because detailing a client's behavior plan to an unauthorised person breaches confidentiality.

D is correct. Treatment fidelity is imperfect in practice; the honest response is to resume correct implementation and document the lapse so the supervisor can interpret the data accurately.

B is wrong because silently skipping leaves the supervisor reading data that misrepresent how the procedure was run. C is wrong because an end-of-session bonus is not contingent on the interval and is an unauthorised modification. A is wrong because concealing a fidelity lapse is a documentation problem, not a fix.

B is correct. DRO — differential reinforcement of other behavior — reinforces the omission of the target behavior across an interval. The client can be doing anything at all, as long as the target behavior did not occur.

A is wrong because DRA requires a specific alternative response to occur. C is wrong because DRI requires a specific incompatible response to occur. D is wrong because DRL reinforces the target behavior at a reduced rate, meaning some occurrences are tolerated.

D is correct. Crisis plans specify what happens after de-escalation — re-entry steps, documentation and notification. Following them protects the client and gives the supervisor the information needed to adjust the plan.

A is wrong because it skips required documentation and notification. C is wrong because ending the session is only appropriate if the plan specifies it. B is wrong because canvassing colleagues for opinions discloses client information beyond those authorised and delays the required report.

C is correct. It reports countable, observable events — number of trials completed independently and number of vocal requests. Another person reading it can picture exactly what happened.

A is wrong because "great mood" and "enjoyed" are inferences about private states. B is wrong because "seemed motivated" is an interpretation rather than an observation; what was observed was a response rate. D is wrong because it combines a vague judgement with an unverified explanation for it.

D is correct. Medication changes are a classic variable that can shift behavior and data. Reporting promptly lets the supervisor interpret any change in the graph correctly rather than attributing it to the intervention.

A is wrong because a private note the supervisor never sees defeats the purpose of the reporting requirement. C is wrong because adjusting the program is a clinical decision outside the RBT's role. B is wrong because probing for medical details exceeds what the RBT needs to know and is not her role to investigate.

C is correct. Client data are protected information. Moving them onto an unsecured personal device — which is backed up to personal cloud storage and accessible to others — is a privacy and record-keeping violation regardless of intent.

A is wrong because image quality is a trivial concern next to the privacy breach. B is wrong because a personal tablet raises exactly the same problem. D is wrong because location is not the issue; secure handling of protected information is.

B is correct. Authorisation, not family relationship, determines who may receive client information. Declining warmly and pointing her to the right person respects both confidentiality and the family.

A is wrong because being a relative does not confer authorisation. C is wrong because a request for discretion does not cure an unauthorised disclosure. D is wrong because it discloses information and offers a clinical judgement the RBT is not qualified to give.

B is correct. The notes must be completed, based on the data actually recorded during those sessions, with the lateness documented honestly and disclosed. That preserves both the record and its integrity.

A is wrong if it means inventing detail from memory rather than working from recorded data — reconstructed narrative presented as contemporaneous is a documentation violation. C is wrong because session notes are required for service verification. D is wrong because a colleague cannot attest to sessions she did not deliver.

A is correct as the answer to avoid. It asserts a diagnostic cause. RBTs do not diagnose, and stating a causal link between a condition and a behavior in a clinical record is both outside scope and unsupported by observation.

B is wrong as a problem because it is a clean count of an operationally defined behavior. C is wrong as a problem because it reports task-analysis data factually. D is wrong as a problem because it documents a relevant, observable session event.

B is correct. Protected information must stay secure in transit. Following the agency's specified method — a locked bag or closed folder, never left unattended in a vehicle — meets both legal and workplace requirements.

A is wrong because papers visible in a car are exposed to anyone who looks in and are a common source of breaches. C is wrong because photographing to a personal device creates a new breach and destroying originals may violate record-retention rules. D is wrong because leaving records in an uncontrolled setting neither secures them nor gets them into the client's file.

B is correct. A house move is a major environmental change that can plausibly affect sleep, routine and behavior — exactly the kind of variable a supervisor needs when interpreting a shift in the data.

A is wrong because the RBT's commute has no bearing on the client. C is wrong because a stationery order is administrative. D is wrong because another client's session is unrelated and discussing it would raise confidentiality questions.

A is correct. Working with the client does not by itself authorise access to diagnostic or medical information. Redirecting the question preserves confidentiality while keeping the professional relationship intact.

B is wrong because proximity to the client is not authorisation. C is wrong because both items are protected information; splitting them does not help. D is wrong because it is false and damages a working relationship the client depends on — RBTs collaborate with school staff within their scope.

A is correct. Session notes serve two functions at once: a clinical record of what was implemented and observed, and verification that the billed service was actually delivered.

B is wrong because personal reflection is not what a clinical record captures. C is wrong because although families may receive updates, that is not the note's purpose or audience. D is wrong because the note documents services delivered; it is not an argument in the RBT's defence.

A is correct. Data are reported as recorded, regardless of who is reviewing them or what decision hangs on them. An unusual session is genuinely informative, and the RBT can note any circumstances she observed.

B is wrong because omitting inconvenient data is falsification by selection. C is wrong because averaging creates a value that was never measured. D is wrong because misstating session length is a documentation and potentially a billing violation.

D is correct. Retention periods for clinical records are set by law, funder rules and agency policy, and complying with them is part of the RBT's documentation responsibilities.

A is wrong because retention is a legal and administrative requirement, not a clinical judgement about a client. C is wrong because retention is mandatory, not discretionary. B is wrong because properly retaining records securely is the opposite of a confidentiality violation.

D is correct. Prognosis is outside the RBT's scope. Taking the question seriously while routing it to the supervisor respects the parent and stays within role.

A is wrong because an opinion on long-term outcome is a clinical prediction an RBT is not qualified to make. C is wrong because although technically cautious, it is dismissive and leaves the parent with nothing. B is wrong because false reassurance is both a scope violation and potentially harmful.

A is correct. "Refused" is a summary that hides the data. Describing how many opportunities were presented and what the client did with each turns an impression into a measurement.

B is wrong because "difficult" adds a second judgement rather than removing the first. C is wrong because the period genuinely happened and belongs in the record — it just needs objective description. D is wrong because speculation about causes does not belong in a factual session note.

D is correct. RBTs are typically mandated reporters. A disclosure of possible harm is escalated immediately through the agency's procedure and to the supervisor — it is not the RBT's job to verify it first.

A is wrong because interrogating a child can contaminate an investigation and is not the RBT's role. C is wrong because documenting without reporting fails the mandated-reporting obligation. B is wrong because approaching the family directly may place the child at greater risk.

C is correct. Data drive clinical decisions. A program that is not working needs to be identified this week, not next month, so late data can mean weeks of ineffective teaching.

A is wrong because workload convenience is a side effect, not the reason. B is wrong because billing is one requirement among several, and the clinical reason is the primary one. D is wrong because supervision requirements are set independently of documentation timeliness.

D is correct. Identifiability does not require a name. Age, presenting behavior and a specific location can be enough to identify a client to anyone in that community, and "private" groups are neither private nor secure.

A is wrong because omitting the name is not the standard; the standard is whether the person could be identified. C is wrong because a bigger audience increases the risk. B is wrong because supervisor approval would not authorise disclosing client information to an online group.

C is correct. Clinical records are corrected through a formal amendment process that leaves a visible trail of what was changed, when and by whom.

A is wrong because a wrong service date affects service verification and possibly billing. B is wrong because deleting destroys the audit trail that record-keeping rules exist to protect. D is wrong because leaving a known-incorrect note in the record alongside a correct one creates a contradictory file.

C is correct. Explaining a procedure the RBT implements is within scope, and flagging the parent's interest lets the supervisor arrange proper caregiver training with the right structure and follow-up.

B is wrong because it needlessly refuses something the RBT can appropriately do. A is wrong because designing a modified home protocol is a clinical decision reserved for the supervisor. D is wrong because handing over a clinical document without explanation is unhelpful and may exceed what the parent is meant to receive unaccompanied.

D is correct. The RBT records what she actually observed — location, size, appearance — without speculation, and escalates it through the agency's procedure so any reporting obligation is handled properly.

A is wrong because questioning the client is investigation, which is not the RBT's role and can compromise a later inquiry. C is wrong because photographing a client's body raises serious privacy and consent problems and is rarely authorised. B is wrong because a casual mention bypasses the required reporting route.

A is correct. The requirement is that reported data are what was actually measured. Submitting estimates as measurements is falsification; that a guess coincided with reality is luck, not accuracy.

B is wrong because the outcome does not change the nature of the act. C is wrong because labelling it does not make estimated data submitted as session data acceptable — the correct action is to record and submit afterward. D is wrong because no supervisor can authorise reporting unmeasured data as measured.

B is correct. Service verification requires the objective facts of the service: when it happened, how long it lasted, where, and what was actually delivered.

A is wrong because opinions about a family are unprofessional and have no place in a clinical record. C is wrong because future planning is the supervisor's domain and belongs in program documentation. D is wrong because referencing other clients in this client's record is a confidentiality breach.

C is correct. The RBT can contribute exactly what she has: direct observations and the data she collected. Interpretation and recommendations require the supervisor's clinical authority.

A is wrong because recommending program changes is a clinical decision outside her scope. B is wrong because RBTs frequently and appropriately attend meetings — the constraint is on what she says, not whether she attends. D is wrong because representing organisational positions on placement is not an RBT function.

D is correct. Physical security of records plus restricting discussion to private spaces and authorised people addresses both the visual and the verbal routes by which information leaks.

A is wrong because a hallway is a shared space and volume does not make it private. C is wrong because initials in a small clinic are usually still identifying. B is wrong because it protects the screen while leaving paper records exposed on the desk.

D is correct. A sustained change in the client's presentation alongside a data drop is exactly the kind of variable the supervisor must know about before drawing conclusions about the program.

A is wrong because delay means the supervisor may misread the graph as a treatment failure. C is wrong because changing reinforcement parameters is an unauthorised plan modification. B is wrong because making medical recommendations is outside the RBT's scope; reporting the observation is not.

C is correct. "Manipulative" is a judgement about motive. Nobody can observe intent, so the claim cannot be verified and it substitutes a characterisation of the client for a description of behavior.

A is wrong because the problem is accuracy and scope, not register. B is wrong because although family readability matters, the note would be improper even if never read. D is wrong because length is not the issue — a longer passage built on the same inference would be equally unacceptable.

A is correct. Babysitting creates a second, personal relationship alongside the professional one. Multiple relationships compromise objectivity and are avoided, and the supervisor should know the request was made.

B is wrong because scheduling is not the problem; the dual role is. C is wrong because avoiding therapy talk does not undo the conflict of interest. D is wrong because a supervisor cannot authorise a relationship the ethics code directs RBTs to avoid, and framing it as approvable misunderstands the issue.

C is correct. Anyone who knows where the RBT works, or which family she sees, can connect the post to a specific child. Sharing clinical progress publicly is a disclosure regardless of whether a name appears.

A is wrong because absence of a name is not the confidentiality standard; identifiability is. B is wrong because adding data would make the breach substantially worse. D is wrong because timing has nothing to do with it.

C is correct. RBT services must be delivered under required supervision. When supervision lapses, the RBT escalates immediately and does not continue practising as an RBT until it is restored.

A is wrong because supervision cannot be back-filled to cover services already delivered without it. B is wrong because supervision must come from a qualified supervisor, not a peer at the same credential level. D is wrong because the requirement is not waived by the cause of the lapse.

C is correct. The RBT is a paraprofessional who delivers behavior-analytic services under the direction of a supervisor who designs the programming and monitors its effects.

A is wrong because designing and modifying plans requires the analytic training of a BCBA or BCaBA. B is wrong because diagnosis is outside the scope of behavior analysis practice at any level, and treatment design is not an RBT function. D is wrong because RBTs do not supervise other RBTs.

B is correct. Gifts of meaningful value create obligation and compromise the professional relationship. Declining warmly and telling the supervisor handles it transparently and protects everyone.

A is wrong because a gift being freely offered does not remove the conflict of interest it creates. C is wrong because distributing it does not change that a significant gift was accepted. D is wrong because concealing it from the employer compounds the problem with a lack of transparency.

C is correct. Cultural humility — new emphasis in the 3rd Edition — means recognising the limits of your own perspective, seeking support, and treating the family's values as information that shapes good service rather than an obstacle.

A is wrong because procedures may be technically similar but goals, reinforcers and family priorities are culturally situated. B is wrong because it puts the burden of adaptation on the family. D is wrong because requesting reassignment on this basis avoids a professional responsibility rather than meeting it.

A is correct. Practising as an RBT requires active certification. Neither close supervision nor a supervisor's say-so substitutes for the credential, and continuing to work risks both the client and the RBT's future certification.

B is wrong because a supervisor cannot authorise practice without an active credential. C is wrong because the violation is practising uncertified, not billing. D is wrong because documenting the lapse does not make the practice permissible.

D is correct. Responding appropriately to feedback means understanding it and actually changing performance. Asking clarifying questions is welcome; quiet non-compliance is not.

A is wrong because leading with a defence of an unauthorised deviation misses that the RBT implements the plan as designed. C is wrong because agreeing while continuing as before is a fidelity and integrity problem. B is wrong because canvassing peers to second-guess the supervisor does not resolve anything and undermines the supervisory relationship.

A is correct. Dignity means privacy for personal routines and age-respectful communication — including with clients who do not speak, since a limited vocal repertoire says nothing about comprehension.

B is wrong because it discusses private information where others can hear. C is wrong because talking about someone as though they are not there is demeaning. D is wrong because raising your voice unnecessarily is neither respectful nor effective.

A is correct. The ethics code obliges RBTs to report conduct that risks client harm. Escalating promptly to the supervisor is the correct route and protects a client who cannot protect himself.

B is wrong because ethical obligations extend to all clients, not only your own caseload. C is wrong because a public confrontation mid-session may escalate the situation and expose the client further. D is wrong because waiting for a second incident leaves the client at risk in the meantime.

A is correct. Scope of competence is defined by training and demonstrated skill, not by willingness. Feeding protocols carry genuine medical risk, so declining until properly trained is the safe and required action.

B is wrong because "careful" improvisation on a risky protocol can harm the client. C is wrong because watching a video is not competency-based training with performance feedback. D is wrong because the parent is not the authorising clinical source for a protocol's implementation.

B is correct. Service decisions belong to the family in conversation with the clinical leadership. The RBT can respond warmly and route it to the person who can actually address it.

A is wrong because offering an opinion on the agency's suitability exceeds her role and may reflect a conflict of interest. C is wrong because a flat refusal is dismissive when a warm redirection is available. D is wrong because recommending a competitor is both outside her role and a conflict of interest.

B is correct. Whether to disclose that a child receives services is the family's decision, not the RBT's. Following the parent's lead protects confidentiality in a public setting.

A is wrong because it discloses that the child is a client to someone with no authorisation. C is wrong because naming the clinic reveals the same information indirectly. D is wrong because stating an untruth about the relationship is dishonest; the RBT can simply defer to the parent without inventing a cover story.

D is correct. RBT supervision requires the supervisor to observe the RBT working directly with a client, because reading a report cannot reveal how a procedure is actually being implemented.

A is wrong because written feedback alone cannot satisfy the observation requirement. C is wrong because supervision is ongoing for as long as the RBT practises. B is wrong because supervision must come from a qualified supervisor at the appropriate credential level, not a peer RBT.

B is correct. Disclosure lets the supervisor evaluate whether the pre-existing relationship compromises objectivity or confidentiality, and reassign if needed. The RBT's job is to surface it, not to judge it alone.

A is wrong because self-assessed objectivity is exactly what conflict-of-interest rules do not rely on. C is wrong because asking a family to change their social life is inappropriate and does not undo the existing relationship. D is wrong because discretion does not resolve a structural conflict of interest.

D is correct. Deciding when a program ends is a clinical judgement made by the supervisor from the data. The RBT's observation is valuable input, delivered through the right channel.

A is wrong because unilaterally discontinuing a program is an unauthorised plan change. C is wrong because parents do not authorise clinical protocol changes. B is wrong because quietly tapering is still an unauthorised modification, and a harder one for the supervisor to detect in the data.

A is correct. Mandated reporting is triggered by reasonable suspicion of abuse or neglect. The RBT reports through the required channel; she does not have to prove anything first.

B is wrong because frequent cancellations may be a clinical or engagement concern but are not in themselves abuse or neglect. C is wrong because lateness is a personnel matter for the employer. D is wrong because lack of progress is a clinical issue for the supervisor to address.

C is correct. Dignity means handling personal care privately, calmly and without commentary, exactly as one would want for oneself.

A is wrong because announcing it to a room exposes something deeply private. B is wrong because leaving the client in that state is a welfare and hygiene problem as well as a dignity one. D is wrong because explaining a client's personal care event to other clients is a confidentiality breach and humiliating.

C is correct. Maintaining the credential involves the annual renewal process, a renewal competency assessment conducted by a qualified supervisor, and continuing to meet supervision requirements while practising.

A is wrong because the 40-hour training is an initial requirement, not an annual one. B is wrong because retaking the examination is not part of routine renewal. D is wrong because CEUs are a requirement for BCBAs, not part of the RBT renewal structure.

B is correct. The RBT implements the plan as designed, and the teacher's concern is legitimate information the supervisor needs in order to adapt the plan to the classroom context.

A is wrong because being in someone else's setting does not transfer clinical authority to them. C is wrong because a flat refusal without explanation or escalation damages a working relationship and leaves the concern unaddressed. D is wrong because a partial modification is still an unauthorised change to the protocol.

B is correct. A social media connection creates a personal relationship layered onto a professional one, and exposes both parties' private lives. Declining kindly, with a brief explanation if appropriate, maintains the boundary without damaging rapport.

A is wrong because rapport is built in sessions, not through personal social media. C is wrong because privacy settings do not change the fact that a dual relationship has been established. D is wrong because silently ignoring can read as personal rejection when a brief professional explanation would prevent that.

B is correct. Goal selection is clinical programming. The RBT welcomes the input and routes it to the supervisor, who can assess whether the skill is appropriate and how to sequence it.

A is wrong because adding goals is not within the RBT's authority, however sensible the goal is. C is wrong because it is false — programs are revised regularly by the supervisor. D is wrong because teaching a skill "informally" is still unauthorised programming and produces no data.

A is correct. Responding well to feedback and advocating for a clinical observation are compatible: implement as directed, then have the conversation with the person who can act on it.

B is wrong because staying silent withholds information the supervisor may genuinely need. C is wrong because continuing unilaterally is a fidelity breach, and documenting it does not authorise it. D is wrong because escalating over the supervisor's head before speaking to her directly skips the appropriate first step.

D is correct. Respecting family values is a professional obligation, and any change to session structure or programming is arranged through the supervisor. Raising it promptly is the responsive action.

A is wrong because dismissing the request outright disregards the family's values and is not the RBT's decision to make. C is wrong because unilaterally restructuring sessions is outside her authority even when well-intentioned. B is wrong because requiring the family to justify a religious practice is intrusive; the request itself is sufficient.

A is correct. The supervisor may have made decisions based on data collected under a flawed procedure. Reporting lets her judge whether the data are usable and whether the program needs revisiting.

B is wrong because stopping the error does not undo its effect on the record. C is wrong because altering past data is falsification. D is wrong because the obligation to report does not depend on a colleague's opinion, and discussing it informally delays it.

A is correct. The RBT credential is defined by working under supervision. A position with no qualified supervisor cannot be performed as an RBT, regardless of the RBT's competence.

B is wrong because compensation is irrelevant to the certification problem. C is wrong because changing employers does not require re-examination. D is wrong because data collection is a practical task she could perform; the barrier is the absence of required supervision.

C is correct. Professional conduct means the client does not absorb the RBT's frustration. Implementing as written and seeking support afterward addresses the real problem — she needs help with the situation.

A is wrong because expressing disappointment to the client is disrespectful and may function as attention for the very behavior in question. B is wrong because leaving a client unattended is a serious supervision and safety failure. D is wrong because reducing demands on her own initiative is an unauthorised plan change made for the RBT's comfort.

C is correct. Reporting what was recorded is within scope when the RBT is authorised to communicate with that parent; interpreting trends and deciding what happens next belongs to the supervisor.

A is wrong because interpreting trends and speaking to prognosis exceeds the RBT role. B is wrong because parents are generally entitled to information about their child's services. D is wrong because offering false reassurance misrepresents the record and undermines trust.
