The real exam delivers 85 questions in 90 minutes: 75 scored plus 10 unscored pilot questions that do not count toward your result.
A. Data Collection and Graphing
Formerly the Measurement domain in the 2nd Edition
7 tasks · ~17% of the exam · 13 of 75 scored questions
- A.1Describe behavior and environment in observable and measurable terms
- Write what you actually saw, not what you think it meant. "Screamed for 12 seconds" is observable; "was frustrated" is an interpretation a second observer could not confirm.
- A.2Prepare for data collection
- Have the right datasheet, timer and materials ready before the session starts, and know which behaviors you are recording and by which procedure.
- A.3Implement continuous measurement procedures
- Frequency and rate, duration, latency, and inter-response time. Continuous means every occurrence in the observation period is captured.
- A.4Implement discontinuous measurement procedures
- Partial interval, whole interval and momentary time sampling. These sample behavior rather than capturing every instance, so each one over- or under-estimates in a predictable direction.
- A.5Implement permanent-product recording procedures
- Measure the lasting result of behavior instead of the behavior itself — worksheets completed, toys put away, dishes washed.
- A.6Enter data and update graphs
- Transfer session data accurately and on time, and plot it on the line graph your supervisor uses to make treatment decisions.
- A.7Assist with interobserver agreement and data accuracy checks
- Record independently alongside a second observer so agreement can be calculated, and follow procedures that keep data accurate and unbiased.

B. Behavior Assessment
Formerly the Assessment domain in the 2nd Edition
5 tasks · ~11% of the exam · 8 of 75 scored questions
- B.1Assist with the assessment of the client's skills and behavior
- Support the assessment process by collecting the data your supervisor specifies. Interpreting the results and designing the program are the supervisor’s job, not yours.
- B.2Conduct preference assessments
- Run paired-stimulus, MSWO, MSWWO, free-operant and single-stimulus assessments to identify what is likely to function as a reinforcer right now.
- B.3Assist with individualized assessment procedures
- Help administer curriculum-based, developmental and social-skills assessments under supervision.
- B.4Assist with functional assessment procedures
- Collect ABC and other descriptive data, and assist with functional analysis conditions when your supervisor directs it.
- B.5Describe motivating operations and their effect on behavior
- Recognise when deprivation or satiation has changed how valuable a reinforcer is, and how that changes behavior right now.
C. Behavior Acquisition
Formerly the Skill Acquisition domain in the 2nd Edition
10 tasks · ~25% of the exam · 19 of 75 scored questions
- C.1Identify the essential components of a written skill acquisition plan
- Know what a plan must tell you: target skill, definition, teaching procedure, prompting and fading, reinforcement, mastery criteria and data collection.
- C.2Prepare for the session as required by the skill acquisition plan
- Gather materials, arrange the environment and set up reinforcers before the client arrives so teaching time is not lost.
- C.3Use contingencies of reinforcement
- Deliver reinforcement contingent on the target response, on the schedule the plan specifies — including conditioned and unconditioned reinforcers.
- C.4Implement discrete-trial teaching procedures
- Run structured trials: SD, prompt as needed, response, consequence, then the inter-trial interval, repeated to build fluency.
- C.5Implement naturalistic teaching procedures
- Teach inside the client’s ongoing activity, following their motivation and using natural reinforcers — incidental teaching, NET, mand training.
- C.6Implement task analysis and chaining procedures
- Break a multi-step skill into its components, then teach with forward, backward or total-task chaining.
- C.7Implement discrimination training
- Reinforce responding in the presence of the SD and withhold it in the presence of the S-delta so the right cue comes to control the behavior.
- C.8Implement prompt and prompt-fading procedures
- Use prompts to make responding successful, then systematically fade them — most-to-least, least-to-most, time delay — so control transfers to the natural SD.
- C.9Implement shaping procedures
- Differentially reinforce successive approximations toward a terminal behavior the client cannot yet perform.
- C.10Implement generalization and maintenance procedures
- Make sure the skill holds up across people, settings and materials, and keeps working after teaching stops.
D. Behavior Reduction
6 tasks · ~19% of the exam · 14 of 75 scored questions
- D.1Identify the essential components of a written behavior reduction plan
- Know what the plan must contain: operational definition, function, antecedent strategies, replacement behavior, consequence procedures and data collection.
- D.2Describe common functions of behavior
- Attention, escape or avoidance, access to tangibles, and automatic reinforcement — and why the same-looking behavior can serve different functions.
- D.3Implement interventions based on modification of antecedents
- Change what happens before the behavior: NCR, high-probability request sequences, choice, priming, and changes to motivating operations.
- D.4Implement differential reinforcement procedures
- DRA, DRI, DRO and DRL — reinforce one class of responding while withholding reinforcement for the problem behavior.
- D.5Implement extinction procedures
- Withhold the reinforcer that has been maintaining the behavior, and be ready for the extinction burst and spontaneous recovery that follow.
- D.6Implement crisis and emergency procedures
- Follow the written safety plan, protect the client and others, and report the incident as required.
E. Documentation and Reporting
Formerly the Documentation domain in the 2nd Edition
5 tasks · ~13% of the exam · 10 of 75 scored questions
- E.1Report variables that might affect the client
- Tell your supervisor about illness, medication changes, sleep, a new sibling, a schedule change — anything that could explain a shift in the data.
- E.2Generate objective session notes for service verification
- Write what happened in observable terms: what was targeted, what the data showed, what you did, without opinion or diagnosis.
- E.3Comply with legal, regulatory and workplace requirements for data collection, storage, transport and documentation
- Handle records the way HIPAA and your employer require — no client data on personal devices, no unsecured transport, no unauthorised disclosure.
- E.4Communicate with stakeholders as authorized
- Share only what you are authorised to share, with the people authorised to receive it, and refer clinical questions to your supervisor.
- E.5Report data and observations accurately and in a timely manner
- Submit real data, on schedule. Never reconstruct, estimate or back-fill numbers you did not actually record.

F. Ethics
Formerly the Professional Conduct and Scope of Practice domain in the 2nd Edition
10 tasks · ~15% of the exam · 11 of 75 scored questions
- F.1Describe the RBT's role in the service delivery system
- You implement plans designed and monitored by a supervisor. You do not design, modify or interpret them.
- F.2Respond appropriately to feedback and maintain or improve performance
- Take supervisory feedback without defensiveness and actually change what you do in the next session.
- F.3Communicate with stakeholders within the scope of the RBT role
- Answer what is yours to answer and route clinical, diagnostic and prognosis questions to the supervisor.
- F.4Maintain professional boundaries and avoid multiple relationships
- No babysitting, no gifts of significant value, no social media connections with client families, no personal relationships that compromise objectivity.
- F.5Maintain client dignity
- Protect privacy, offer choice, speak about clients respectfully, and never discuss them where they or others can overhear.
- F.6Comply with supervision requirements
- Meet the required supervision percentage each month, including direct observation with a client, and stop practising if supervision lapses.
- F.7Maintain confidentiality and comply with privacy requirements
- Client information is disclosed only with authorisation — including anonymised details, which are often still identifying in a small community.
- F.8Comply with the RBT Ethics Code and reporting requirements
- Follow the code, and report to the BACB and to authorities where required — including mandated reporting of suspected abuse or neglect.
- F.9Maintain certification requirements
- Keep renewal, the annual renewal competency assessment and supervision current. An expired credential means you may not practise as an RBT.
- F.10Practise within scope of competence with cultural humility and responsiveness
- New in the 3rd Edition. Recognise the limits of your training, and adapt respectfully to the family’s culture, language and values.
