- A. 80% ✔

Sample questions
Six real questions from the bank, one from each Task List domain. These are not written for this page — they are the same items you will meet in the exam itself.
Question 2
B · Behavior AssessmentDuring a preference assessment, the client chooses the iPad. You remove the iPad and present the remaining items. This is:
- A. MSWO ✔
- B. MSW
- C. Free Operant
- D. Paired Choice
Why: Multiple Stimulus Without Replacement (MSWO) removes the selected item.

C · Behavior AcquisitionYou provide reinforcement after an average of 3 correct responses. This is:
- A. VR-3 ✔
- B. FR-3
- C. FI-3

Why: VR (Variable Ratio) is based on an average number of responses.
Question 4
D · Behavior ReductionA functional behavior assessment (FBA) determines:
- A. The diagnosis
- B. The IQ
- C. The 'Why' (Function) of behavior ✔
- D. The medication list
Why: FBAs identify the function (cause/maintenance) of behavior.
Question 5
E · Documentation and ReportingYou just finished a 2-hour session with a client. When should you write your session notes?
- A. The next morning when you're fresh
- B. During the next client's session
- C. Immediately after the session while details are fresh ✔
- D. At the end of the week in a batch
Why: Session notes should be written immediately after the session to ensure accuracy while the details are still fresh in memory.
Question 6
F · EthicsYou discover that a colleague (another RBT) has been fabricating data — recording correct responses that didn't actually happen. What should you do?
- A. Ignore it — it's not your client
- B. Report it to your supervising BCBA immediately ✔
- C. Confront them publicly
- D. Help them fix the data
Why: Data fabrication is a serious ethical violation that can harm clients. You must report it to your supervisor immediately.
What the exam covers
The RBT Task List splits into six domains. Every mock exam here is drawn from all six, so a low score tells you which one to go back to.
A. Data Collection and Graphing
Continuous and discontinuous measurement, permanent product recording, entering data and updating graphs, describing behavior in observable terms, and spotting trends.
B. Behavior Assessment
Running preference assessments, and assisting with assessments of skill strengths and deficits and with functional assessments.
C. Behavior Acquisition
Implementing the skill-acquisition plan: discrete trial teaching, naturalistic procedures, task analysis, chaining, prompting and fading, generalization and maintenance.
D. Behavior Reduction
Implementing the behavior-reduction plan: identifying antecedents and consequences, differential reinforcement, extinction, and crisis procedures.
E. Documentation and Reporting
Session notes, objective reporting, communicating with the supervisor, and the legal and workplace rules around records.
F. Ethics
Scope of practice, the supervisor relationship, dual relationships and conflicts of interest, confidentiality, dignity, and maintaining certification.

Frequently asked questions
How many questions are on the real RBT exam?
85 total questions (75 scored, 10 unscored), 90 minutes. The 10 unscored questions are pilot items being trialled for future exams; you cannot tell them apart while you sit it, so treat every question as if it counts.
What score do I need to pass?
The BACB scores the RBT exam on a scaled system rather than a raw percentage, so there is no published percentage that guarantees a pass. On practice exams, treat 80%+ as the point where you are consistently ready rather than scraping through.
Is this practice test really free?
Yes. This exam and 2 of our 7 full mock exams need no account, no card and no trial. The remaining mocks are part of RBT Pro at $10.99 a month.
Do I need to create an account?
Not to take the exam or see your score. An account is only useful if you want your results kept so you can compare attempts over time — your progress is saved on this device either way.
How many times can I retake it?
As many times as you like. The questions are shuffled on each attempt, so retaking is worth doing rather than a memory test of the answer order.
Is this exam timed?
No. The real exam gives you 90 minutes for 85 questions, which is roughly a minute each — but this practice exam lets you take as long as you need, so you can read the explanation after every question while it is fresh. Time yourself once you are scoring well.
Are the questions the same as the real exam?
No, and nowhere selling you real exam questions is doing so legally. These are written to the same Task List domains at the same difficulty, which is what makes practice useful.
How long should I study before taking the RBT exam?
Most candidates sit it within a few weeks of finishing the 40-hour training. The more useful signal than time spent is a stable practice score: if you are clearing 80%+ across different mock exams rather than one lucky attempt, you are ready.
