What Is an RBT Practice Exam?
An RBT practice exam is a timed set of multiple-choice questions that mirrors the Registered Behavior Technician certification exam: 85 questions (75 scored, 10 unscored), 90 minutes, four answer choices each, covering six domains from data collection to ethics. Start with the free 20-question quiz above, then move to a full-length 85-question mock exam when you score 85% or higher.
Full-Length RBT Practice Exams and Mock Tests
Full-length RBT practice exams are free, timed tests of 75 or 85 questions that copy the real exam’s 90-minute, 4-option format. Once you score 85% on the 20-question quiz above, switch to these. Each exam below needs no account and explains every answer, and the question mix follows the domain weights in the BACB’s RBT Test Content Outline (3rd ed.).

Domain-by-domain exam practice is the fastest way to raise a weak score. Each of the 6 domains below has its own quiz, flashcards, and study guide, and the label shows how many of the 75 scored questions that domain contributes, according to the BACB. Start with Behavior Acquisition (19 questions) and Behavior Reduction (14 questions), which together make up 44% of the exam.
A. Data Collection & Graphing
Continuous and discontinuous measurement, rate, trends in graphed data.
B. Behavior Assessment
Preference assessments, skills assessments, and functional assessment.
C. Behavior Acquisition
Reinforcement, DTT, naturalistic teaching, chaining, prompting, shaping.
D. Behavior Reduction
Functions of behavior, antecedent strategies, differential reinforcement, extinction.
E. Documentation & Reporting
Objective session notes, reporting variables, seeking clinical direction.
F. Ethics
Supervision, confidentiality, multiple relationships, gifts, social media.
What Is the RBT Exam?
The RBT exam is the certification test for the Registered Behavior Technician® credential, issued by the Behavior Analyst Certification Board (BACB). RBTs deliver applied behavior analysis (ABA) services under the close, ongoing supervision of a BCBA, BCaBA, or other qualified supervisor. The exam is delivered by Pearson VUE and checks whether you can apply entry-level ABA skills in real session scenarios, not just define terms.
| RBT exam detail (2027) | What to expect |
|---|---|
| Number of questions | 85 multiple-choice: 75 scored + 10 unscored pilot questions (you won’t know which are which) |
| Time allowed | 90 minutes (about 63 seconds per question) |
| Answer format | 4 answer choices, 1 correct answer |
| Content outline | RBT Test Content Outline (3rd ed.), 43 tasks in 6 domains |
| Where you test | Pearson VUE (see the RBT Handbook for current testing options) |
| Fees | $65 BACB application fee + $45 Pearson VUE exam appointment = $110 |
| Result | Reported as pass/fail |
| Retakes | Up to 8 attempts within 12 months of application approval, with 7 days between attempts |
Because unscored pilot questions are mixed in, treat every question as if it counts. A good RBT practice exam copies this format so the real RBT exam feels familiar, and a full mock exam under time pressure is the closest free practice you can get before test day.
RBT Exam Content Outline (3rd Edition): The 6 Domains
Since 2026, the RBT certification exam is built on the BACB’s RBT Test Content Outline (3rd ed.), which replaced the old RBT Task List (2nd ed.). It contains 43 tasks across six domains. Behavior Acquisition is the largest, so it deserves the most study time.
| Domain | Tasks | Scored questions | Share of exam |
|---|---|---|---|
| A. Data Collection and Graphing | 8 | 13 | 17% |
| B. Behavior Assessment | 3 | 8 | 11% |
| C. Behavior Acquisition | 11 | 19 | 25% |
| D. Behavior Reduction | 7 | 14 | 19% |
| E. Documentation and Reporting | 4 | 10 | 13% |
| F. Ethics | 10 | 11 | 15% |
| Total | 43 | 75 | 100% |
A. Data Collection and Graphing
Domain A, Data Collection and Graphing, covers 8 tasks and 13 scored questions (17%) in the BACB’s RBT Test Content Outline (3rd ed.). Know continuous measurement (frequency, duration, latency, interresponse time), discontinuous measurement (partial interval, whole interval, momentary time sampling), and permanent product recording. Expect to calculate rate, mean duration, and percentage, to spot trends in a graph, and to explain why unreliable data and poor procedural fidelity put client progress at risk. Practice reading line graphs for level and trend.
B. Behavior Assessment
Domain B, Behavior Assessment, has 3 tasks and 8 scored questions (11%), according to the BACB’s 3rd edition outline. Questions focus on preference assessments (multiple stimulus, paired stimulus, free operant) and your supporting role in skills assessments, such as curriculum-based or developmental tools, and in functional assessment, such as descriptive ABC data collection. Remember that the RBT collects data as directed; the supervising BCBA interprets the results and identifies the function of behavior. Know which preference assessment suits a client who struggles with many items at once.
C. Behavior Acquisition
Domain C, Behavior Acquisition, is the largest: 11 tasks and 19 scored questions (25%) in the BACB’s RBT Test Content Outline (3rd ed.). It’s often called skill acquisition. Study positive and negative reinforcement and schedules, conditioned reinforcers, discrete-trial teaching, naturalistic teaching (incidental teaching, NET), forward, backward, and total task chaining, discrimination training, prompting and prompt fading, generalization vs. maintenance, shaping, and token economies. Many questions describe a short session and ask which procedure is being used.
D. Behavior Reduction
Domain D, Behavior Reduction, covers 7 tasks and 14 scored questions (19%) under the BACB’s 3rd edition outline. Identify the 4 common functions of behavior (attention, escape, tangible, automatic), then apply antecedent interventions (NCR, high-probability request sequences, demand fading), differential reinforcement (DRO, DRA, DRI, DRL, FCT), extinction, punishment procedures, and crisis or emergency procedures. Know the side effects of extinction, such as the extinction burst, response variation, and resurgence. Always match the intervention to the function, and follow the written behavior plan.
E. Documentation and Reporting
Domain E, Documentation and Reporting, has 4 tasks and 10 scored questions (13%), according to the BACB’s RBT Test Content Outline (3rd ed.). Expect “what should the RBT do?” questions about writing objective session notes, reporting illness, medication, or schedule changes in a timely manner, passing along caregiver and teacher concerns, and seeking clinical direction from your supervisor. The right answer usually describes observable behavior and follows the chain of command rather than acting alone.
F. Ethics
Domain F, Ethics, covers 10 tasks and 11 scored questions (15%) in the BACB’s 3rd edition outline. It is based on the BACB’s ethics code for RBTs: working only within your competence and under ongoing supervision, protecting confidential information, making honest public statements (including on social media), avoiding multiple relationships, following gift rules, using professional skills such as accepting feedback, and practicing cultural humility. Scenario answers that involve informing the supervisor are often correct. When in doubt, choose the client’s welfare.
How to Use an RBT Practice Exam to Pass the First Time
To pass the RBT exam with practice tests, diagnose your weak domains first, drill them, then finish with timed 85-question mocks. Exam-style practice tests are the most effective RBT exam prep, but only if you review your misses after each of your study sessions. This four-week plan works for most candidates who have finished the 40-hour training and the RBT competency assessment. It uses only free study materials from this site.
- Week 1: Diagnose. Take RBT Practice Exam 1 untimed. Note your score in each domain.
- Week 2: Fix weak domains. Use the domain quizzes, RBT exam flashcards, and the RBT study guide for any domain under 80%. Review the RBT terms glossary for vocabulary gaps.
- Week 3: Practice under time. Take Practice Exams 2 and 3 in 90 minutes each. For every missed question, write one line on why the right answer is right.
- Week 4: Simulate test day. Take the 85-question practice exam and Practice Exam 4 in one sitting with no notes or phone.
| Your practice exam score | What it usually means | Next step |
|---|---|---|
| 85% or higher, twice in a row | Likely ready | Schedule your Pearson VUE exam |
| 70–84% | Close, with gaps in one or two domains | Drill weak domains, retest in 1 week |
| Below 70% | Core concepts need review | Return to the study guide, then retake Exam 1 |
These score bands are our study recommendations. The BACB does not publish a percentage cut score.
Common Mistakes on RBT Exam Questions
The most common mistake on RBT exam questions is choosing an answer that goes beyond the RBT’s role. The BACB’s 3rd edition outline expects RBTs to implement plans under supervision, so watch for these five errors:
- Acting outside your scope of practice. RBTs implement plans; they don’t design or change them. On the actual exam, the correct response usually involves following the plan and checking with the supervising BCBA.
- Mixing up interval methods. Partial interval overestimates; whole interval underestimates; momentary time sampling checks only the end of the interval.
- Confusing reinforcement and punishment. Reinforcement increases behavior and punishment decreases it. “Positive” means adding and “negative” means removing.
- Ignoring the function. In behavior reduction scenarios, ask what the behavior gets the client (attention, escape, tangible, or sensory) before choosing an answer.
- Running out of time on exam day. With about one minute per question, flag hard items and come back to them.
RBT Exam Eligibility Requirements
To be eligible for the RBT exam, the BACB RBT Handbook requires you to meet all of the following before you apply:
- Be at least 18 years old and have a high school diploma or equivalent.
- Pass a criminal background check and an abuse registry check.
- Complete a 40-hour RBT training that meets the current BACB requirements.
- Complete the Initial Competency Assessment with a qualified assessor.
- Submit your application and pay the $65 fee, then book the exam with Pearson VUE ($45) within one year of approval.
Requirements and fees can change, so confirm them in the current RBT Handbook on the BACB website before you apply.
RBT Practice Exam: Frequently Asked Questions
Is this RBT practice exam free?
Yes. Every practice test on RBTPracticeExam.net is free and needs no account: the 20-question quiz above, four full practice exams, the 75- and 85-question mock exams, six domain quizzes, flashcards, and study guides. You only pay official fees when you apply, which the BACB RBT Handbook lists as a $65 application fee plus a $45 Pearson VUE exam appointment. Free practice works best when you read the explanation for every question you miss. No email or payment details are ever requested.
How many questions are on the RBT exam, and how long does it take?
The RBT exam has 85 multiple-choice questions and a 90-minute time limit. According to the BACB RBT Handbook, 75 questions are scored and 10 are unscored pilot questions mixed in at random, so you can’t tell which ones count. Each question has 4 answer choices and 1 correct answer. That works out to about 63 seconds per question, so practice with a timer and flag hard items to revisit. Leave the last 5 minutes to review flagged questions.
What score do I need to pass the RBT exam?
The BACB reports RBT exam results as pass or fail and does not publish a fixed percentage or raw cut score in the RBT Handbook. Because the 75 scored questions come from 6 domains, one weak area such as Behavior Acquisition (19 questions) can sink an otherwise good result. As a study benchmark, aim for 85% or higher on two full-length practice exams in a row before you book your Pearson VUE appointment. Practice under timed conditions so that benchmark means something.
Is the RBT exam hard?
The RBT exam is manageable with preparation, but it isn’t a vocabulary test. Most of the 85 questions are short session scenarios that ask what an RBT should do next, so you need to apply concepts like extinction, prompting, and confidentiality rather than just define them. Behavior Acquisition alone makes up 25% of scored questions under the BACB’s 3rd edition outline. Practice exams with explanations are the fastest way to build that applied skill. Read every option before you choose.
How long should I study for the RBT exam?
Most candidates study for 2 to 6 weeks after finishing the 40-hour RBT training and the Initial Competency Assessment. A practical schedule is 4 weeks: one diagnostic test, two weeks of domain drills, then timed 85-question mock exams in the final week. The BACB RBT Handbook gives you 1 year from application approval to sit for the exam, so there is no need to rush. Book your test once you score 85% or more consistently.
Can I take the RBT exam online?
The RBT exam is delivered by Pearson VUE, the BACB’s testing partner. Testing options and ID rules are set out in the current BACB RBT Handbook and on your Pearson VUE scheduling page, so check both before you book. Whichever option you use, your ID must match the name on your BACB account exactly. For a side-by-side look at the options, see our guide to Pearson VUE vs. remote proctoring for the RBT exam. Arrive or log in early on exam day.
What should I do if I fail the RBT exam?
If you fail, wait at least 7 days, then book a new attempt with Pearson VUE; according to the BACB RBT Handbook, each attempt needs a new $45 appointment. Use your practice exam scores to find your weakest domains, drill those with the domain quizzes on this site, and retake full-length practice exams until you score 85% or higher. You have up to 8 attempts within 12 months of your application approval, so a single failed attempt is a setback, not the end.
How often can I retake an RBT practice exam?
You can retake every practice exam on this site as often as you like, at no cost. Retakes are useful for review, but your score rises partly because you remember the questions, so it overstates your readiness. For an honest check, rotate between Practice Exams 1 to 4 and the 85-question mock, and leave 2 to 3 days between attempts at the same test. The real exam, by contrast, allows up to 8 attempts in 12 months under BACB rules.
How many times can I retake the RBT exam?
According to the BACB RBT Handbook, you can take the RBT exam up to 8 times within 12 months of your application approval, with at least 7 days between attempts. Each attempt requires booking and paying for a new $45 Pearson VUE appointment. Plan your attempts so you don’t run out of time in your 12-month window, and use each waiting period to drill your weakest domains with targeted quizzes and timed exam practice. Don’t rush a retake.
How much does the RBT exam cost?
The RBT exam costs $110 in total: a $65 application processing fee paid to the BACB and a $45 exam appointment fee paid to Pearson VUE, according to the BACB RBT Handbook. Each retake needs another $45 appointment. The 40-hour training, the Initial Competency Assessment, and your background check are separate costs that vary by provider, and many ABA employers cover them for new hires. Ask your employer before paying out of pocket, because policies vary and some reimburse the exam fee after you pass.
Are these RBT practice exams updated for the latest task list?
Yes. Our practice exams follow the BACB’s RBT Test Content Outline (3rd ed.), which replaced the RBT Task List (2nd ed.) for exams starting in 2026. The 3rd edition has 43 tasks in 6 domains: Data Collection and Graphing, Behavior Assessment, Behavior Acquisition, Behavior Reduction, Documentation and Reporting, and Ethics. Older practice tests built on the 2nd edition use different domain names and weightings, so check the edition before you study. Everything on this site uses the current 3rd edition.
How closely do RBT practice exams match the real exam?
A good RBT practice exam matches the real test’s format closely: 4-option multiple-choice questions, realistic session scenarios, and the domain weighting the BACB publishes, such as 19 Behavior Acquisition questions out of 75. No practice exam uses the actual questions, because the BACB keeps them confidential. Use full-length timed mocks to match the 90-minute pace, and treat your practice score as an estimate rather than a guarantee. Scores of 85% or higher on unseen practice tests are a strong sign you’re ready for test day.
