RBT Exam Pass Rates, 2021 to 2025

In 2025, 75% of first-time Registered Behavior Technician (RBT) candidates passed the exam, according to the BACB, out of 109,341 people testing for the first time. Retakers fared far worse: 38% of the 54,674 retake candidates passed. The first-time rate has stayed between 73% and 77% since 2022, so roughly one first-time candidate in four does not pass.

What were the RBT pass rates each year?
First-time pass rates were 83% in 2021, 77% in 2022, 74% in 2023, 73% in 2024 and 75% in 2025. Retake pass rates over the same years were 53%, 44%, 41%, 36% and 38%. The 2021 figures exclude one region the BACB removed for anomalous activity; with every region included, 2021 was 79% for first-time candidates and 46% for retakes.
Is the RBT exam hard?
Most first-time candidates pass, but about a quarter did not in each of the last four years, and retakers pass at much lower rates, 36% to 44% since 2022. The BACB does not publish a passing percentage: it sets the cut score with the modified Angoff method, a criterion-referenced approach, and reports pass or fail rather than a score, with failing candidates told which tasks they answered incorrectly.
Do pass rates differ by training program?
Yes, widely. The BACB publishes first-time pass rates for each publicly available 40-hour training provider with 10 or more first-time candidates, and in the 2025 report those provider rates ranged from 8.1% to 100%. Looking up your program’s figure is a fair check on how well it prepares candidates.
How many times can I take the RBT exam?
Up to 8 attempts within the 12 months after your application is approved, waiting at least 7 days between them. If all 8 are used while time remains, you must wait for the 12-month period to end before reapplying for certification.
How many RBTs are there?
The BACB counted 259,577 people holding RBT certification as of October 1, 2026.

Judge the difficulty yourself

These are three RBT practice questions at exam difficulty. See where you land. The app has 3,000+, timed and scored.

Question 1

An RBT scores completed math worksheets at the end of an independent study period as a permanent product measure of academic output. The client finished all assigned problems with 100% accuracy, but the paraprofessional reports that the client showed visible signs of physical strain and fatigue while writing. What is a key limitation of relying solely on permanent product recording in this situation?

▸ Why C is the answer

A primary limitation of permanent product recording is that it only measures the post-behavior environmental outcome, not the actual process or effort of responding. It does not capture whether the student experienced physical fatigue or distress during the task, potentially masking significant learner discomfort or strain behind an accurate finished product. The claim that it cannot confirm the total number of academic problems completed accurately is incorrect, as verifying completed problems is precisely what permanent product measurement does. Permanent product measurement does not require continuous direct observation of the student; that is a feature of direct observation systems. It also does not inherently overestimate academic engagement on graphs.

🔑 Key takeaway

Permanent product recording measures only the final outcome and cannot reflect client fatigue or physical strain.

Question 2

An RBT discovers that their BCBA has been signing monthly supervision verification forms for observation hours that did not occur. The RBT discusses the issue directly with the BCBA, but the supervisor dismisses the concern and refuses to correct the logs. What is the BEST next step for the RBT?

▸ Why D is the answer

When an informal resolution regarding an ethical violation fails or is unproductive, the RBT must escalate the concern appropriately, such as notifying clinical leadership or submitting a formal notice of alleged violation to the BACB. Dropping the matter permits ongoing fraud and violates the technician's duty to uphold ethical standards. Continuing to sign false documents makes the RBT complicit in document falsification despite private notes. Involving the client's family in internal supervision disputes is unprofessional and places an inappropriate burden on clients.

🔑 Key takeaway

When an informal ethical resolution fails, the RBT must escalate the issue to leadership or the BACB.

Question 3

An RBT provides in-home behavioral services during evening hours when their BCBA is not on-site. The client has a history of sudden, intense physical aggression toward family members. What must the supervisor provide to ensure effective supervision and safety during these sessions?

▸ Why A is the answer

Effective supervision practices require supervisors to establish explicit emergency protocols and available contact channels for RBTs handling acute behavioral crises outside direct supervision hours. Pre-recorded generic training videos do not provide direct, crisis-specific support when an emergency unfolds. Authorizing an RBT to discharge a client is inappropriate, as discharge decisions rest solely with the supervising behavior analyst. Providing alternative behavioral diagnoses exceeds the RBT and BCBA scopes of practice, as diagnostic evaluations are restricted to qualified medical or psychological practitioners.

🔑 Key takeaway

Supervisors must establish explicit emergency protocols and crisis contacts for off-site sessions.
