Why 75 and not 85? The real exam delivers 85 questions but scores only 75; the other 10 are pilot items being trialled for future forms. This version gives you the scored length at the real weighting.

The real RBT exam format

The RBT examination is delivered at Pearson VUE test centres. 85 multiple-choice questions in 90 minutes, four options each, of which 75 are scored and 10 are unscored pilot items. The BACB uses scaled scoring and publishes no fixed percentage pass mark.

Frequently asked questions

How many questions are on the RBT exam?
The RBT exam delivers 85 multiple-choice questions. Only 75 of them are scored — the other 10 are unscored pilot questions the BACB is trialling for future exams, and you cannot tell which is which while you are testing. You get 90 minutes for all 85, which works out to roughly 63 seconds per question.
What score do you need to pass the RBT exam?
There is no fixed percentage. The BACB uses scaled scoring, which converts your raw score to a scaled score to account for small differences in difficulty between exam forms, and it does not publish a percentage pass mark. Many candidates use 80% on full-length practice exams as a personal readiness benchmark, but that is a study target people set for themselves — not the pass mark, and no practice site can tell you the number you need.
How long is the RBT exam?
You have 90 minutes to answer all 85 questions. The appointment itself runs longer because of check-in, ID verification and the tutorial at the testing centre, so allow extra time. Pace matters more than most candidates expect: 90 minutes for 85 questions is about 63 seconds each, which is why our exams run a real countdown clock.
Are these practice questions the real RBT exam questions?
No, and you should be sceptical of any site that claims otherwise. Real exam items are secure and copyrighted, and reproducing them would be both illegal and a violation of the BACB Ethics Code. Every question here is original, written independently against the publicly published RBT Test Content Outline (3rd Edition), and matched to the same domain weighting and question format as the real exam.
Do free RBT practice exams actually help?
They help most when they do two things: match the real domain weighting, so you are not over-practising one area, and explain why each wrong option is wrong, so a missed question teaches you something. Practice questions that only tell you the right answer train recognition rather than understanding. Taking at least one full-length attempt under a real 90-minute clock is also worth doing, because running out of time is a distinct problem from not knowing the content.
Do I need to create an account?
No. There is no sign-up, no email wall and no paywall anywhere on this site. Your answers, flags and timer are saved in your own browser using localStorage, so you can close the tab mid-exam and pick up where you left off — nothing is uploaded to us.
