How to use this free 85-question RBT practice exam
Use this set for a full-length practice session: 85 multiple-choice questions in one sitting, with an optional 90-minute limit. If you are learning the material rather than checking your pace, turn the timer off before starting.
- Choose timed or untimed. Start free without an account, email or payment card.
- Answer, navigate and flag. Use Previous, Next or the question navigator. Answers save on this browser; a running timer does not pause when you leave.
- Finish for the answer review. Unanswered questions count as incorrect. Read the correct answer, the explanation and why the other three choices do not fit. Source links are included in the review.
What your practice score does—and does not—tell you
Every practice question is scored, so the result is correct answers out of 85. That percentage is feedback on this set, not a BACB scaled score or a validated prediction of passing.
The BACB third-edition Test Content Outline specifies 75 scored questions plus 10 unscored pilot questions. The official exam is 85 questions in 90 minutes. Our practice questions are not actual BACB exam items, and all 85 count here; there is no hidden pilot allocation.
Six RBT content domains: what to review next
Start with the explanation for a missed question, then use the matching guide and topic quiz. The familiar study labels Measurement, Skill Acquisition and Professional Conduct lead to the corresponding current content areas.
B. Behavior Assessment
9 questions in this set
Distinguish preference assessments, ABC observations and the technician’s role.
C. Behavior Acquisition
22 questions in this set
Review reinforcement, prompting, chaining and generalization.
D. Behavior Reduction
16 questions in this set
Review antecedents, differential reinforcement and plan-based responses.
E. Documentation and Reporting
11 questions in this set
Review objective notes, relevant changes and communication with the supervisor.
F. Ethics
12 questions in this set
Review boundaries, confidentiality, supervision and scope of competence.
What to do after finishing
- Choose one recurring mistake. Include answers you guessed correctly, not only the red marks.
- Study the rule, then apply it. Open the relevant guide and focused quiz. Use free SAFMEDS recall cards for terms you cannot yet explain.
- Try a different set. Retaking the same items tests familiarity too. Check whether you can explain the decision in a new scenario.

Frequently asked questions
Is this a free full-length RBT practice exam?
Yes. You can complete 85 multiple-choice practice questions, see your score and review every explanation without an account or payment. The 90-minute timer is optional.
Is the 2026 RBT exam 75 or 85 questions?
The official exam delivers 85 questions, including 75 scored and 10 unscored pilot questions. This independent practice exam scores all 85; it does not reproduce official pilot items or the BACB scoring scale.
Are these actual BACB exam questions?
No. These are independent educational questions mapped to the six domains in the RBT Test Content Outline, third edition, used from 2026. RBTHub is not affiliated with or endorsed by the BACB.
How do I get answers and explanations?
After finishing, select a question from Question Review or use Review All Questions. The review shows the correct choice, an explanation, analysis of the other options and sources. Skipped questions count as incorrect.
What should I do after a low practice score?
Read the explanations for missed and uncertain questions, study the matching concepts, then try different questions. Use the domain guides below; a practice score is not a pass prediction or a reason to abandon preparation.
Can I leave and resume this practice exam?
