RBT Exam Pass Rate, Format & Study Guide

The Registered Behavior Technician (RBT) certification is the BACB's entry-level credential for people who implement behavior-analytic services under supervision. The written exam has 85 multiple-choice questions (75 scored) in 90 minutes and follows the RBT Test Content Outline (3rd edition).

Employers and payers in autism and behavioral health services commonly require or prefer the RBT credential for direct-service staff. Certification shows that you completed the 40-hour training, were assessed on core skills and passed a standardized exam.

Aspiring behavior technicians, paraprofessionals and therapy assistants who work with a BACB-certified supervisor, and applicants who have already completed the 40-hour training and the Initial Competency Assessment.

The BACB's RBT pass-rate page (updated May 2026) shows a first-time pass rate of about 79% and a retake pass rate of about 46% (figures taken from a search extract of the page; the full table also reports results by 40-hour training provider).

If you do not pass, you may retake the exam up to the limits in the BACB's RBT Handbook (the BACB limits the number of attempts within an application's authorization period) and pay the US$45 exam appointment fee again. Retakers pass at a much lower rate than first-time test takers, so read the handbook's retake rules and review the Ethics and Behavior Acquisition areas before rebooking.

The RBT exam is scored pass/fail. Of the 85 questions, 75 are scored and 10 are unscored pilot questions that you cannot tell apart, so answer every question. The BACB reports results as pass or fail rather than percentages.

The exam contains 85 multiple-choice questions, of which 75 are scored and 10 are unscored pilot items. You have 90 minutes. The result is pass or fail and the exam is delivered by Pearson VUE.

The BACB's certification application processing fee is US$65 for applications on or after January 1, 2026, and the Pearson VUE exam appointment costs US$45. Training programs, supervision and the competency assessment may carry separate fees from your employer or training provider.

Behavior Acquisition (25%) and Behavior Reduction (19%) are the largest content areas, followed by Data Collection and Graphing (17%), Ethics (15%), Documentation and Reporting (13%) and Behavior Assessment (11%).
