The Registered Behavior Technician (RBT) exam is built from one document: the BACB Test Content Outline (3rd ed.). It lists 43 tasks grouped into six domains, and every question maps to one of those tasks.
The single biggest change for 2026 is the reorganisation into six domains with new weightings. If you studied from older 2nd Edition Task List materials, read our 3rd Edition vs 2nd Edition guide to see exactly what moved.
The six RBT domains at a glance
| Domain | What it covers | % | Practice |
|---|---|---|---|
| A — Data Collection & Graphing | Frequency, duration, IRT, latency, graphing | 17% | Quiz → |
| B — Behavior Assessment | Preference and functional assessment | 11% | Quiz → |
| C — Behavior Acquisition | DTT, chaining, prompting, shaping | 25% | Quiz → |
| D — Behavior Reduction | Functions, DRA/DRO, extinction, crisis | 19% | Quiz → |
| E — Documentation & Reporting | Objective notes, communication | 13% | Quiz → |
| F — Ethics | Confidentiality, scope, conduct | 15% | Quiz → |
Each domain, explained
Data Collection & Graphing
This is the measurement backbone of ABA. Know the difference between frequency, rate, duration, latency, and interresponse time (IRT), plus the three discontinuous methods (whole-interval, partial-interval, momentary time sampling). You'll be asked to read line graphs and cumulative records, so practise interpreting trend and level.
Behavior Assessment
Smaller but very learnable. Focus on the types of preference assessments (single-stimulus, paired-stimulus, MSWO) and your role in functional assessment — you assist, you don't design. Know the ABC (antecedent-behavior-consequence) recording format cold.
Behavior Acquisition
The heaviest domain — spend the most time here. Master discrete-trial teaching (DTT), the prompt hierarchy (and how to fade prompts), shaping vs chaining, task analysis, and token economies. Expect scenario questions that ask which teaching procedure fits a situation.
Behavior Reduction
Learn the four functions of behavior (attention, escape, access, automatic) and the differential reinforcement family (DRA, DRO, DRI, DRL). Understand extinction and the extinction burst, and know your role in following a written crisis/emergency plan.
Documentation & Reporting
Practical and often underestimated. Write objective, measurable session notes (observable behavior, not opinion), know what must be reported to your supervisor and when, and understand session-note timeliness and data integrity.
Ethics
Built on the RBT Ethics Code. Know confidentiality (HIPAA basics), your scope of practice, the supervision requirements, dual relationships, and social-media boundaries. Ethics questions are usually scenario-based — pick the most professional response.
A 6-week RBT study schedule
Foundations & measurement
Read Domain A end to end. Learn every measurement type and practise reading graphs. Do the Domain A quiz twice.
Assessment & the biggest domain
Cover Domain B, then start Domain C (it's 25% of the exam). Focus on DTT and the prompt hierarchy.
Finish acquisition & start reduction
Finish Domain C, then learn Domain D — the four functions and differential reinforcement. Quiz both.
Documentation & ethics
Work through Domains E and F. Practise writing objective session notes and answering ethics scenarios.
Mixed practice
Stop studying by domain. Take full mixed quizzes daily and review every wrong answer until you know why.
Full mock exams
Sit timed full-length practice exams. Aim to finish comfortably inside 90 minutes and score 85%+ before booking.
Exam day: what to expect
- Arrive early. Log in or check in 15 to 30 minutes ahead.
- Bring valid ID. A government-issued photo ID with a matching name is required.
- 90 minutes, 85 questions. Just over a minute per question. Flag hard ones and move on.
- Answer every question. No penalty for guessing.
- Read scenario questions twice. They often hinge on one word.
- You will get an unofficial result at the end; the official result follows from the BACB.

As of 2026, the Behavior Analyst Certification Board (BACB) uses the RBT Test Content Outline (3rd ed.). It replaces the older 2nd Edition Task List and reorganizes the exam into six domains (A–F). If you test in 2026 or later, you are on the 3rd Edition.
The RBT exam has 75 scored questions plus 10 unscored pilot questions, for 85 total. The pilot questions do not count toward your score. You have 90 minutes to finish.
Domain A — Data Collection & Graphing (17%); B — Behavior Assessment (11%); C — Behavior Acquisition (25%); D — Behavior Reduction (19%); E — Documentation & Reporting (13%); F — Ethics (15%). Domain C is the heaviest, so most candidates should spend extra time there.
You need a scaled score of 200 out of 300 to pass. BACB reports the result as pass/fail. Because questions vary in difficulty, there is no fixed number of correct answers required.
Most candidates are ready in about six weeks of steady study — roughly one domain per week, then two weeks of mixed and full-length practice. If you already work in ABA, you may need less.
Start with the domain you find hardest, not your favourite. Read the task list, then immediately do practice questions so you find gaps early. Finish with full-length timed practice exams so the real thing feels familiar.
Most people who fail underestimate Domain A (measurement) and Domain D (behavior reduction), where the wording is precise. Steady daily practice with real questions is more reliable than re-reading notes.
The RBT exam fee is $50, paid to Pearson VUE when you schedule. This is separate from the 40-hour training and the assessment your supervisor completes.
