Full-Length Mock Exam
85-Question RBT Mock Exam
Content reviewed by Dr. Sarah Mitchell, BCBA-D
This 85-question RBT mock exam matches the exact question count of the real BACB Registered Behavior Technician exam. Treat it like the real thing: find a quiet space, set a 90-minute timer, and work through every domain with instant scoring and detailed explanations.
Timed exam: you have 90 minutes to finish, matching the pacing of the real test. The countdown starts when the first question loads and the exam submits automatically when time runs out.
What does 'transfer of stimulus control' mean in behavior acquisition?
A true full-length rehearsal
The Registered Behavior Technician exam is 85 questions long, and this mock exam gives you every one of them. Where a short quiz tells you whether you know a concept, a full-length run tells you whether you can hold that knowledge together across the entire test window. That distinction matters more than most candidates expect. The material that feels effortless in a ten-question drill can start to blur when you are eighty minutes in, deciding between two plausible answers for the fortieth time. Practicing at the real count is the only way to find out how your judgment behaves under sustained load — and to fix it before the stakes are real.
Of the 85 items on the official exam, 75 are scored and 10 are unscored pilot questions the BACB embeds to trial for future forms. You will not be able to tell which is which, and neither will this mock exam ask you to. That is the point: on test day you treat all 85 with equal care, so your practice should ask the same of you. Answer each item as if it counts, because as far as your concentration is concerned, it does.
Recreate real test-day conditions
A mock exam is only as useful as the conditions you take it under. The BACB allots 90 minutes for the 85 questions, which works out to just over a minute per item with a small buffer. Set a single 90-minute timer, silence your phone, and commit to one uninterrupted block. Resist the urge to pause and look something up; every time you break the flow to check a definition, you are studying, not testing, and you lose the honest readiness signal a mock exam exists to give you. Save the learning for the review phase afterward, when every explanation is waiting for you.
Pay attention to how the last twenty questions feel compared with the first twenty. If your accuracy drops noticeably in the final stretch, the fix is rarely more content review — it is stamina and pacing. Candidates who fade late often benefit from a deliberate mid-exam reset: a slow breath, a shoulder roll, a quick check of the clock, then back to work. Building that small routine now means it is automatic when it matters.
What the 85 questions cover
Every item is a four-option multiple-choice question sampled proportionally from all six areas of the RBT Test Content Outline (3rd Edition). Because the set is proportional, behavior-change procedures and skill acquisition carry the heaviest weight, mirroring the real exam, while measurement, assessment, documentation, and professional conduct appear in their true proportions. The table below shows what sits inside each domain so you can convert a low section score into a concrete study target rather than a vague worry.
| RBT Task List Domain | What it covers | Study |
|---|---|---|
| Data Collection and Graphing | Measurement systems, continuous and discontinuous data, interobserver agreement, and reading behavior graphs. | Guide |
| Behavior Assessment | Preference assessments, the RBT's role in functional assessment, and supporting the BCBA during assessment. | Guide |
| Behavior Acquisition | Discrete-trial teaching, naturalistic teaching, prompting and fading, shaping, chaining, and skill acquisition plans. | Guide |
| Behavior Reduction | Functions of behavior, differential reinforcement, extinction, antecedent strategies, and crisis procedures. | Guide |
| Documentation and Reporting | Objective session notes, incident reports, communication with the supervisor, and maintaining records. | Guide |
| Ethics and Professional Conduct | The RBT Ethics Code, professional boundaries, scope of practice, confidentiality, and supervision requirements. | Guide |
Understanding scaled scoring
The BACB does not publish a fixed passing percentage for the RBT exam because it uses a scaled scoring model. Different forms of the exam vary slightly in difficulty, and scaling adjusts for that so no candidate is penalized for drawing a harder version. The practical consequence is that you should not chase a magic raw number. Instead, aim to answer roughly 80 percent of your practice questions correctly and to do it consistently across several attempts. A single lucky run above threshold is far less reassuring than steady scores in the low-to-mid 80s across different sittings.
Get the most from each attempt
- Take the whole thing in one sitting. Splitting it into chunks defeats the stamina practice that is the entire reason to sit an 85-item exam.
- Flag and keep moving. If an item stalls you past a minute, commit to your best answer, flag it mentally, and press on. Protecting your momentum protects your score.
- Review every rationale, right or wrong. Confirming why the correct option beats the distractors cements the concept better than a green checkmark ever will.
- Log your weak domains. After each attempt, write down the two lowest-scoring domains and drill those before retaking the full exam.
- Retake after focused study. The question order reshuffles, so a second full-length run gives you a clean read on real improvement.
Where to go from here
If you are still building toward full length, step back to the 75-question practice exam to match the scored count without the extra pilot items. To rehearse the on-screen testing interface itself, work through the Pearson VUE-style simulation. When your results flag a soft spot, drill it directly with the ethics practice quiz or review core terms with our free RBT flashcards and the RBT study guide.
