Every one of our 195 practice questions, with the correct answer marked and a full written explanation covering why that answer is right and why each of the other three is wrong. No timer, no scoring — this is the reading version, split by domain so you can work through one area at a time.
Aligned to the RBT Task List 3rd Edition (effective 1 January 2026) · Last content review: August 2026 · How we write our questions
The six domains below are the RBT Test Content Outline (3rd Edition) domains, in the order the BACB lists them. The percentage is that domain’s share of the real exam, so if you are short on time, start at the top of the list rather than the top of the alphabet.
Formerly the Measurement domain
Choosing and running the right measurement procedure, recording accurately, and reading a line graph the way a supervisor expects you to.
~17% of the real exam · 13 of the 75 scored questions
Formerly the Assessment domain
Assisting with preference assessments and functional behavior assessments, and knowing exactly where an RBT’s role stops.
~11% of the real exam · 8 of the 75 scored questions
Formerly the Skill Acquisition domain
The largest domain on the exam — teaching procedures, prompting, reinforcement and the transfer of new skills to real settings.
~25% of the real exam · 19 of the 75 scored questions
Running a behavior reduction plan as written — including the parts candidates most often get wrong, like extinction bursts and DRO intervals.
~19% of the real exam · 14 of the 75 scored questions
Formerly the Documentation domain
Writing notes that are objective and legally defensible, and reporting variables that affect the client to the right person at the right time.
~13% of the real exam · 10 of the 75 scored questions
Formerly the Professional Conduct and Scope of Practice domain
Judgement-based items drawn from the RBT Ethics Code — dual relationships, gifts, social media, supervision and scope of practice.
~15% of the real exam · 11 of the 75 scored questions
Reading answers and sitting an exam train different things. Reading builds the reasoning — why a distractor is tempting and what makes it wrong — while a timed attempt trains recall and pace. The sequence that works best is to take a full-length exam first, look at which domain came back weakest, then read that domain’s page here before retaking. Working straight through all 195 in order is the least efficient way to use them.
Every question is original, written in-house against the publicly published RBT Test Content Outline (3rd Edition) and tagged to a specific task list item. None of them are real exam items — those are secure and copyrighted, and any site claiming to have them is worth leaving. More on that in how we write our questions.
The number of questions on each page above is not proportional to the real exam — the pool is deliberately deeper in the domains people find hardest. This is the actual weighting you will face on test day.
| Domain (3rd Edition) | Formerly | Weight | Scored Qs |
|---|---|---|---|
| A. Data Collection and Graphing | Measurement | ~17% | 13 |
| B. Behavior Assessment | Assessment | ~11% | 8 |
| C. Behavior Acquisition | Skill Acquisition | ~25% | 19 |
| D. Behavior Reduction | — | ~19% | 14 |
| E. Documentation and Reporting | Documentation | ~13% | 10 |
| F. Ethics | Professional Conduct and Scope of Practice | ~15% | 11 |
| Total | 100% | 75 |
The real exam delivers 85 questions in 90 minutes: 75 scored plus 10 unscored pilot questions that do not count toward your result.
Take the 85-question practice exam under a real 90-minute clock, or the 75-question scored-length version that matches the BACB’s published split exactly, or the full-length mock exam for a second, independent set of questions once you have already seen these. All three end in a per-domain breakdown that points you back to the pages above.
