Measurement · Data Collection & Graphing
An RBT records whether a target behavior is occurring at the exact moment each 30-second interval ends. Which measurement procedure is being used?
Momentary time sampling scores the behavior only if it is occurring at the precise moment the interval ends — unlike partial interval (any point during the interval) or whole interval (the entire interval).
Assessment · Behavior Assessment
During a paired-stimulus preference assessment, the RBT should present items:
A paired-stimulus (forced-choice) preference assessment presents items two at a time so each item is paired with every other item, producing a clear preference hierarchy.
Skill Acquisition · Behavior Acquisition
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:
Backward chaining teaches the final step of a task analysis first, so the learner always contacts the natural reinforcer of task completion, then adds earlier steps in reverse order.
Behavior Reduction
A behavior plan reinforces a learner for every 10-minute period in which self-injury does not occur. This procedure is:
DRO delivers reinforcement contingent on the absence of the target behavior for a specified interval — reinforcing "any other behavior" during that period.
Professional Conduct & Scope of Practice
A parent asks the RBT to change part of their child's behavior intervention plan. The RBT should:
Designing or modifying intervention plans is outside the RBT scope of practice. RBTs implement plans and must direct all modification requests to the supervising BCBA or BCaBA.

Exam Guide
What Is the RBT Exam?
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, about 75% of first-time candidates passed in 2025 (and only 38% of retakers) — and structured practice testing is the single biggest factor separating first-time passers from retakers.

2026 Update
RBT Exam Changes in 2026: Task List 2nd Edition → TCO 3rd Edition
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) |
Scored questions by content area (RBT Handbook, October 2026): Data Collection and Graphing 13 · Behavior Assessment 8 · Behavior Acquisition 19 · Behavior Reduction 14 · Documentation and Reporting 10 · Ethics 11 (total 75).
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.

Core Concepts
Key ABA Concepts Tested on the RBT Exam
Many RBT exam questions are short scenarios that test whether you can apply core applied behavior analysis (ABA) concepts. Review these guides alongside your practice tests.
Seven Dimensions of ABA
Applied, behavioral, analytic, technological, conceptually systematic, effective and generality — with examples.
The ABC Model
How antecedents, behaviour and consequences fit together in ABC data collection and functional assessment.
Antecedents in ABA
What counts as an antecedent, setting events and antecedent interventions you'll see in exam scenarios.
ABA Techniques
Prompting, shaping, chaining, DTT, NET and reinforcement strategies RBTs use every day.
Effective Dimension of ABA
Why socially significant, measurable change is the test of whether an intervention works.
The RBT Role
Duties, supervision requirements and career path for ABA assistants and RBTs.

Study Plan
How to Pass the RBT Exam on Your First Try: 5-Step Plan
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.
Complete the BACB 40-hour RBT training
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.

Why It Works
Why an RBT Practice Exam Beats Re-Reading Your Notes
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.

Questions Answered
RBT Practice Exam — Frequently Asked Questions
What is an RBT practice exam?
An RBT practice exam is a simulated version of the official Registered Behavior Technician certification test administered by the BACB. Ours include four 20-question practice tests and an 85-question, 90-minute mock exam covering all six Test Content Outline domains, so you can identify knowledge gaps, build pacing, and pass the real exam on your first attempt.
How many questions are on the RBT exam in 2026?
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.
What score do I need to pass the RBT exam?
The RBT exam is scored pass/fail. The BACB sets the passing standard with the modified Angoff method (a panel of certified experts) and does not publish a fixed percentage or raw cut score. As a practical target, aim for 80% or more on fresh practice questions — 68+ out of 85 on our mock exam — before booking.
How hard is the RBT exam? What's the pass rate?
The RBT exam is challenging but very passable with structured preparation. According to BACB-reported data, about 75% of first-time candidates passed in 2025, and only 38% of retakers passed. Candidates who struggle usually memorized definitions without practicing applied, scenario-based questions — which is exactly what full-length practice exams train.
Is this RBT practice exam really free?
Yes. All four practice exams, the 85-question mock exam 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 for every question included.
Did the RBT exam change in 2026?
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.
What topics are covered on the RBT exam?
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.
How long should I study for the RBT exam?
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.
Can I retake the RBT exam if I fail?
Yes. The BACB allows up to 8 attempts within your 12-month exam authorization period, with at least 7 days between attempts. No retake application fee is currently charged, but each new Pearson VUE appointment costs $45. 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%+.
How long does the RBT exam take, and where do I take it?
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.
