Pass the Registered Behavior Technician exam on your first attempt. Every RBT practice exam on this site mirrors the real BACB test — 85 multiple-choice questions, a 90-minute timer, instant scoring, and detailed answer explanations — and is fully aligned to the 2026 BACB Test Content Outline (3rd Edition).
Quick answer: An RBT practice exam is a free, simulated version of the BACB's Registered Behavior Technician certification test. It matches the real format — 85 multiple-choice questions (75 scored, 10 unscored pilot items), a 90-minute limit, and a 200/250 scaled passing score — so you can find weak domains, practice pacing, and pass the RBT exam on your first attempt.
Four full-length mock exams with unique question banks, timed to real test conditions. Take Exam 1 early to diagnose weak domains, then use Exams 2–4 to confirm you're consistently scoring 80% or higher before booking Pearson VUE.

An RBT records whether a target behavior is occurring at the exact moment each 30-second interval ends. Which measurement procedure is being used?
During a paired-stimulus preference assessment, the RBT should present items:
A learner can already brush their teeth when prompted through each step. The RBT now teaches the last step first, adding earlier steps only after the final step is mastered. This is:
A behavior plan reinforces a learner for every 10-minute period in which self-injury does not occur. This procedure is:
A parent asks the RBT to change part of their child's behavior intervention plan. The RBT should:
The Registered Behavior Technician (RBT) exam is the certification test administered by the Behavior Analyst Certification Board (BACB). It verifies that a candidate can deliver applied behavior analysis (ABA) services safely and competently under the supervision of a Board Certified Behavior Analyst (BCBA). The RBT credential is the entry-level certification for careers in ABA therapy across clinics, schools, and home-based programs — most often supporting individuals with autism spectrum disorder.
After completing the 40-hour training, competency assessment, and application, candidates sit the exam in person at a Pearson VUE testing center and receive an unofficial pass/fail result immediately. According to the BACB's most recent annual data, roughly 79–80% of candidates pass on their first attempt — and structured practice testing is the single biggest factor separating first-time passers from retakers.

On January 1, 2026, the BACB replaced the RBT Task List (2nd Edition) with the RBT Test Content Outline (TCO) 3rd Edition. If your study materials still say "Task List 2nd Edition," they are out of date. Every practice exam and study guide on this site has been rewritten for the 3rd Edition, including the renamed domains below.
| Task List 2nd Edition (through 2025) | TCO 3rd Edition (2026 onward) |
|---|---|
| Measurement | Data Collection and Graphing |
| Assessment | Behavior Assessment |
| Skill Acquisition | Behavior Acquisition |
| Behavior Reduction | Behavior Reduction (revised content areas) |
| Documentation and Reporting | Documentation and Reporting (updated requirements) |
| Professional Conduct and Scope of Practice | Professional Conduct and Scope of Practice (updated ethics & supervision) |
Study tip: the acquisition and reduction domains together carry the largest share of scored questions on the exam, so prioritize them if your study time is limited — but don't skip measurement, where small wording differences (partial vs. whole interval, latency vs. duration) cost easy points.
The 2026 exam draws every question from six domains of the BACB Test Content Outline. Each summary below links to targeted practice so you can drill your weakest area.
Frequency, duration, latency, and interval recording (partial, whole, momentary time sampling), permanent product, inter-observer agreement (IOA), and reading line graphs and cumulative records.
Preference assessments (single-, paired-, and multiple-stimulus), functional behavior assessment (FBA), functional analysis, motivating operations, and writing operational definitions.
Discrete trial teaching (DTT), natural environment teaching (NET), prompting and fading, shaping, forward/backward/total-task chaining, verbal operants, reinforcement schedules, and generalization.
Extinction, differential reinforcement (DRA, DRI, DRO, DRL), functional communication training (FCT), antecedent interventions, response cost, time-out, and crisis protocols.
Objective session notes, accurate data recording, graphing, communicating with supervisors and caregivers, record retention, and HIPAA rules for protected health information.
The RBT Ethics Code, confidentiality, professional boundaries, supervision requirements, scope-of-practice limits, mandatory reporting, and annual renewal.
Cognitive-science research on the "testing effect" shows that retrieval practice — answering questions from memory — builds far stronger retention than re-reading notes. This plan is built around it.
This mandatory training, usually provided by your employer or an accredited program, covers every TCO content area. Take notes on ABA terminology, measurement procedures, and the RBT Ethics Code — all heavily tested.
Download the TCO 3rd Edition from the BACB website and work through it alongside our free RBT study guide, which explains every domain with real-world examples.
Take RBT Practice Exam 1 under real conditions — 90 minutes, no notes, no phone. Score honestly and note your two weakest domains. This diagnostic is where most candidates discover their real gaps.
Spend 7–14 days on your weakest areas using the domain summaries above and the study guide, then confirm improvement with Practice Exam 2 and Practice Exam 3. Aim for a consistent 80%+ (68 of 85) before booking.
Schedule through your BACB account, bring a valid government photo ID, and arrive 30 minutes early. Answer every question, flag anything uncertain, and use leftover time to review. If you don't pass, you can retake after a 7-day wait — run Practice Exam 4 first to close the gap.

Practice testing does three things passive study can't. First, it exposes knowledge gaps by domain — our instant score breakdown shows exactly whether Measurement, Assessment, Acquisition, Reduction, Documentation, or Ethics needs work, so you stop studying blindly. Second, it trains exam pacing: 85 questions in 90 minutes is just over a minute per question, and timed mocks make that rhythm automatic. Third, it reduces test anxiety — one of the most common reasons prepared candidates still fail — by making the format, difficulty, and pressure familiar before test day.

An RBT practice exam is a simulated version of the official Registered Behavior Technician certification test administered by the BACB. It mirrors the real format — 85 multiple-choice questions (75 scored, 10 unscored pilot items), a 90-minute limit, and questions from all six Test Content Outline domains — so you can identify knowledge gaps, build pacing, and pass the real exam on your first attempt.
The 2026 RBT exam has 85 multiple-choice questions: 75 scored and 10 unscored pilot questions the BACB uses to test future items. You won't know which is which, so treat every question as scored. You have 90 minutes to complete the exam at a Pearson VUE testing center.
You need a scaled score of 200 out of 250. Because scoring is scaled to the difficulty of your exam version, there is no fixed raw cutoff, but this generally corresponds to roughly 80% of scored questions correct — about 60 of 75. On our practice exams, aim for 68+ correct out of 85 before booking your real test.
The RBT exam is challenging but very passable with structured preparation. Per the BACB's annual data, approximately 79–80% of candidates pass on their first attempt. Candidates who struggle usually memorized definitions without practicing applied, scenario-based questions — which is exactly what full-length practice exams train.
Yes. All four full-length practice exams, the domain quizzes, and the complete study guide are 100% free. No account, no email address, and no payment details are required — select a test and start immediately, with instant scoring and full answer explanations included.
Yes. From January 1, 2026, the BACB replaced the RBT Task List (2nd Edition) with the Test Content Outline (3rd Edition). Domain names changed — Measurement became Data Collection and Graphing, Assessment became Behavior Assessment, and Skill Acquisition became Behavior Acquisition — and content areas and question distribution were revised. All practice exams on this site reflect the 3rd Edition.
Six domains: (1) Data Collection and Graphing — frequency, duration, latency, and interval recording plus IOA; (2) Behavior Assessment — preference assessments and functional behavior assessment; (3) Behavior Acquisition — DTT, NET, prompting, shaping, and chaining; (4) Behavior Reduction — extinction, differential reinforcement, and antecedent strategies; (5) Documentation and Reporting — session notes, graphing, and HIPAA; and (6) Professional Conduct and Scope of Practice — ethics, confidentiality, and supervision.
Most candidates study 2–4 weeks after finishing the 40-hour training. Working in an ABA setting while you study shortens this, since hands-on experience reinforces the concepts. Plan for at least two or three full-length timed practice exams during that window, with targeted domain review between attempts.
Yes. The BACB allows up to 8 attempts within your 12-month exam authorization period, with a 7-day wait between attempts and a $50 fee each time. Before retaking, review your score report to find your weakest domains, drill them with practice exams, and only rebook once you're consistently scoring 80%+.
The exam is 90 minutes and is taken in person at a Pearson VUE testing center — you schedule it through your BACB account after your application is approved. Most candidates finish in 60–80 minutes, leaving time to review flagged questions, and you receive an unofficial pass/fail result immediately.
