RBT Exam Guide: The BACB Registered Behavior Technician Exam, Explained
The Registered Behavior Technician (RBT) is the Behavior Analyst Certification Board’s paraprofessional credential for the people who carry out behavior-analytic services directly with clients — running teaching procedures, collecting data, and implementing behavior plans designed and overseen by Board Certified Behavior Analysts (BCBA) and other qualified supervisors. This guide explains the credential and the examination from the BACB’s own published materials: eligibility, the training and competency requirements, exam content, scoring, and keeping the credential current.
Who is eligible
To apply for RBT certification, a candidate must be at least 18 years old, hold a high school diploma or the equivalent, and pass a criminal background check. The candidate then completes a 40-hour training based on the RBT Test Content Outline and passes the RBT competency assessment, in which a qualified assessor observes the candidate demonstrating the outline’s tasks. Only after those steps does the candidate sit for the examination. The credential is not a one-time event: the competency assessment is renewed annually, and every RBT practices under ongoing supervision — at least 5% of the hours spent providing behavior-analytic services are supervised each month, with at least two synchronous contacts per month, at least one of them individual, and the supervisor observing the RBT deliver services.
The exam at a glance
| Questions | 85 (75 scored + 10 unscored pilot) |
| Time | 90 minutes |
| Format | Four-option multiple choice |
| Delivery | Pearson VUE test centers |
| Result | Reported as pass or fail; the BACB publishes no passing percentage |
The examination is a high-volume one — the BACB’s registry counts RBTs among the largest credentials it administers — and it is taken after the training and competency steps, as the final gate before certification.
The six domains
| Domain | Exam questions | What it covers |
|---|---|---|
| A. Data Collection and Graphing | 13 | Continuous and discontinuous measurement, permanent product recording, entering data and updating graphs, describing behavior in observable terms, summarizing data, reading trends |
| B. Behavior Assessment | 8 | Preference assessments, assisting with skill assessments, participating in functional assessment procedures |
| C. Behavior Acquisition | 19 | Reinforcement and conditioned reinforcers, discrete-trial and naturalistic teaching, chaining, discrimination training, prompting and fading, generalization and maintenance, shaping, token economies |
| D. Behavior Reduction | 14 | Functions of behavior, antecedent interventions, differential reinforcement, extinction and its side effects, punishment procedures, crisis and emergency procedures |
| E. Documentation and Reporting | 10 | Communicating with supervisors and the intervention team, seeking clinical direction, reporting variables that affect client progress, objective session documentation |
| F. Ethics | 11 | The RBT Ethics Code (2.0): core principles, competence, supervision, confidentiality, public statements, multiple relationships, gifts, and professional skills |
Behavior Acquisition is the largest domain — the exam rewards technicians who can run teaching procedures correctly and contingently, not just describe them. Data Collection and Graphing runs a close second in weight, which surprises candidates who expect a purely procedural exam: measurement and graphing are tested as working skills, including calculations such as rate and percentage.
The current outline
Examinations beginning January 1, 2026 follow the RBT Test Content Outline (3rd edition), which organizes the credential’s 43 tasks into the six domains above. Preparation materials built to an earlier edition of the outline distribute questions differently from the exam now in use; candidates sitting in 2026 should prepare to the third edition’s task list and weights — which is how our RBT Exam Prep bank is built and weighted.
Scoring, explained honestly
The BACB reports the RBT examination result as pass or fail. It does not publish a passing percentage, and it does not release a scaled passing score, so there is no honest number a preparation provider can quote you as “the score you need.” What you can control is coverage and accuracy in each of the six domains. Our practice exams use a 70% practice benchmark purely as a readiness gauge — it is our number, not the BACB’s.
After the exam: supervision and renewal
Certification begins a supervised practice, not an independent one. RBTs provide services only under ongoing supervision from supervisors who meet BACB requirements, implement supervisor-designed plans, and renew the competency assessment annually. The Ethics Code (2.0) governs daily practice throughout — including confidentiality, boundaries with clients and families, and the rule that an RBT neither gives nor accepts gifts worth more than $10 from clients, stakeholders, or supervisors. Domain F of the examination tests exactly this working knowledge.
A study plan that fits the outline
- Baseline: take a full practice exam and record your score by domain, not just overall.
- Drill the gaps: work the domain drills for your weakest domain — measurement calculations and discrimination-training procedures both improve fast with repetition.
- Re-test under time: take fresh full exams inside the 90-minute limit until your domain scores are consistent.
- Schedule: book your Pearson VUE sitting while the material is warm.

Verified questions
Every question in this program is original — written for PassProfessor from the official exam blueprint, never copied from a test bank or another provider’s materials. Before enrollment opened, each answer key was independently verified: reviewers re-answered sampled questions blind, disagreements were settled against the primary sources, and every numeric answer was recomputed from first principles. Questions whose facts could not be confirmed were removed, and the bank passed a text-overlap screen. Practice exams draw a fresh, blueprint-weighted set from the full bank on every attempt, so no two practice exams are the same.
