About This Site

Why this exists

There is no shortage of free RBT practice exams. What is in short supply is one that is actually current, actually explains its answers, and actually tells you what to study next.

When the BACB moved to the RBT Test Content Outline (3rd Edition) for exams from 1 January 2026, several of the most visible free practice sites did not follow. They still teach the retired 2nd Edition domain names and the old question weighting, under a badge saying they are up to date. If you are staking a certification attempt and a job on that material, that matters.

This site was built on the current edition from the first question, and says so in a way you can verify — every question is tagged to a task item, and every exam page prints its real domain mix.

What is different here

Four things, all of which are checkable rather than claimed:

• Every one of our 195 questions explains why the correct answer is right AND why each of the other three options is wrong.
• The results screen gives you a per-domain breakdown, a weakest-domain callout that links straight into the matching quiz and study guide section, and a pace comparison against the real exam’s 63-seconds-per-question.
• A real exam simulation: a 90-minute countdown that survives a refresh, flag-for-review, and a question navigator — the mechanics candidates say catch them out on the day.
• Progress saves in your own browser, so you can close a tab mid-exam and resume, with no account and nothing uploaded.

What this site does not do

No sign-up. No email address required to see your score. No countdown timers pressuring you to "unlock" anything. No fake scarcity. No paywall. No claim that these are real exam questions, because they are not and nobody legitimate has them.

We also do not tell you that 80% is the pass mark, because it is not. The BACB uses scaled scoring and publishes no percentage threshold.

What we do not have yet

We do not have a named BCBA reviewer. The questions are written and checked in-house against the published content outline, and we think they are good — but they have not been reviewed by someone with a verifiable behavior-analytic credential, and we are not going to imply otherwise.

That is the strongest trust signal available in this niche, and the honest position is to say we are working on it. When we have a real reviewer, their name and certification number will appear on the pages they reviewed.

Who runs it

This site is independently built and maintained. It is not affiliated with the BACB, with Pearson VUE, or with any ABA training provider, and it does not take payment from any of them.

It is free to use and, at present, carries no advertising.

Tell us when we are wrong

Every question has a "Report a problem with this question" control. If you believe an answer key or an explanation is wrong, please use it. Confirmed errors get corrected, and the question bank is version-controlled so corrections are auditable.
