Five More RBT Practice Questions, Answered and Explained
Use these five questions as a quick self-check after the practice exam above. Pick your answer before you expand the explanation, which walks through why the right option fits the scenario and why each of the other choices falls short. Every question is labeled with its content area from the 2026 RBT Test Content Outline (3rd Edition).
1. Jessica checks every 5 minutes and counts how many students are on task at that instant. What measurement system is she using?
- A) Whole-interval recording
- B) Partial-interval recording
- C) Momentary-time sampling
- D) Continuous recording
Show answer & explanation
Correct answer: C — Momentary-time sampling
The key phrase is at that instant. Momentary-time sampling records whether the behavior is happening only at the exact moment each interval ends, which makes it practical for observing a group or when you are busy running other programs. Whole-interval recording (A) requires the behavior to occur for the entire interval, so Jessica would have to watch continuously for all 5 minutes. Partial-interval recording (B), the common wrong pick, scores the interval if the behavior occurs at any point during it, not just at the end. Continuous recording (D) captures every occurrence across the whole observation, the opposite of a brief spot check.
Domain: Data Collection and Graphing
2. You place 5 toys in front of a learner. The learner picks one and plays with it briefly. That toy isn’t returned, and you present the remaining toys again until all have been chosen. What type of preference assessment is this?
- A) Paired-stimulus
- B) Multiple-stimulus without replacement (MSWO)
- C) Multiple-stimulus with replacement (MSW)
- D) Free-operant observation
Show answer & explanation
Correct answer: B — Multiple-stimulus without replacement (MSWO)
Two details point to MSWO: several items are presented at once, and the chosen item is not returned to the array. Because the options shrink each round, the order of selection produces a ranked list of the learner’s preferences. MSW (C) is the common wrong pick; it also uses a multi-item array, but the chosen item goes back in, so the learner may pick the same favorite repeatedly. Paired-stimulus (A) presents only two items at a time. Free-operant observation (D) lets the learner move freely among items without any being removed, and you record how long they engage with each.
Domain: Behavior Assessment
3. Joy’s lawnmower starts after 1, 2, or sometimes 3 pulls of the cord, averaging two. What reinforcement schedule best describes this?
- A) Fixed-ratio
- B) Variable-ratio
- C) Fixed-interval
- D) Variable-interval
Show answer & explanation
Correct answer: B — Variable-ratio
Ask two questions: is reinforcement based on responses or time, and is the requirement fixed or changing? The mower starts after a number of pulls (responses), and that number changes around an average of two, so it is a variable-ratio (VR2) schedule. Fixed-ratio (A) would require the same number of pulls every time. Fixed-interval (C) and variable-interval (D) make reinforcement available only after an amount of time has passed, so pulling more often would not help. Variable-ratio schedules produce high, steady responding that is very resistant to extinction, which is why slot machines use them.
Domain: Behavior Acquisition
4. Nathan teaches hand-washing by fully prompting all steps except the last one, which he teaches first. He then works backward until all steps are mastered. What procedure is this?
- A) Forward chaining
- B) Backward chaining
- C) Total-task chaining
- D) Task analysis only
Show answer & explanation
Correct answer: B — Backward chaining
In backward chaining, the learner is taught the final step first while you prompt all earlier steps; then you add the step before it, and so on until the learner completes the whole chain independently. A big advantage is that the learner finishes the task and contacts the natural reinforcer (clean, dry hands) from the very first session. Forward chaining (A) starts with the first step and moves forward. Total-task chaining (C) teaches every step on every trial, prompting only where needed. Task analysis (D) is the common wrong pick: it breaks the skill into steps, but it is the plan, not the teaching procedure that decides the order steps are taught.
Domain: Behavior Acquisition
5. During a session, your client trips and bumps their head. They seem fine and go back to playing. What should you do?
- A) Continue the session, since the client isn’t hurt
- B) Mention it to the caregiver at pickup only
- C) Follow your organization’s incident procedure: document it objectively and notify your supervisor promptly
- D) Note it in next week’s session summary
Show answer & explanation
Correct answer: C — Follow the incident procedure, document, and notify your supervisor
Any injury during a session, even a minor one, is an incident that must be documented and reported according to your organization’s policy and timelines. Your note should be objective: what happened, when, what you did, and how the client responded. Continuing without reporting (A) is the tempting pick, but deciding the client is unhurt is not an RBT’s call, and symptoms of a head injury can appear later. Telling the caregiver only (B) skips both the written record and your supervisor, who needs to know about anything that could affect the client. Waiting until next week (D) makes documentation late and less accurate; session notes and incident reports should be completed promptly.

Frequently Asked Questions
Are these the exact questions from the real RBT exam?
No. They’re original practice items written to match the 2026 BACB ® RBT Test Content Outline.
Is the RBT exam 75 or 85 questions?
The real RBT exam has 85 questions in total, with 75 questions scored, and 10 questions unscored.
Try our 85-question practice exam here!Which domains have the most questions on the RBT exam?
The domain with the most questions is Behavior Acquisition, with 19 of the 75 scored questions. See the table in the “Domains Covered” section above for a full breakdown of each domain. If you haven’t already, make Behavior Acquisition a priority in your studying.
How should I study after I see my score?
Focus first on any domain that fell below 80%. Use the matching units and our free Study Guide, then retake a different 75-question or 85-question form.
How should I time this 75-question practice test?
The real exam is timed at 90 minutes for 85 questions. So for a 75-question practice exam, we recommend completing all questions within 80 minutes. That’s roughly 1 minute per question.
RBTs are expected to stay in good standing with the BACB. This includes renewing their RBT license as required. Part of the renewal process is retaking the competency assessment. How often do RBTs need to retake the competency assessment?
Every 6 months
Every year
Every 3 year
Every 5 year
All of these options are incorrect seeing as the requirement is now 2 years.
Hi Marie,
Appreciate you pointing that out. You’re right that the BACB is moving RBT recertification to a 2-year cycle based on PDUs. This question was focusing on the competency assessment. During current transition, existing RBTs may still be required to complete an annual competency assessment before shifting fully into the PDU-based cycle.
We’ve updated the wording to better match the current BACB requirements. Thanks again for catching it!
Thank you so much for these practice questions. Hopefully these practice tests will help me pass the exam in 4 days.
I’m sure these practice questions will help you in pass the exam and get the RBT certification. All the best.
Which schedule of reinforcement do the rainbow tokens most closely align with?
Fixed ratio
Variable interval
Conjugate
Variable ratio
How is it the correct answer is – Conjugate
please explain
I actually just disregarded this question as incomplete since I can’t find anything definitively defining “Rainbow Tokens” and there was no example of a schedule of reinforcement in the question.
Every six months, Emily receives her favorite bottle of wine from her boss as a thank you for her hard work. Her siblings drank the entire bottle the last two times when they visited. The next time they visited, Emily hide the bottle and served other wine. What type of intervention did Emily implement?
it should be letter C. Avoidance right?
it is the type of intervention emily implemented. avoidance involves taking action to prevent an unwanted situation from occuring
Emily implemented an antecedent intervention, specifically response prevention.
By hiding the bottle of wine before her siblings arrived, she altered the environment to prevent the undesired behavior (them drinking her favorite wine). Response prevention is a proactive strategy that involves modifying the environment to make an undesired behavior less likely to occur.
Emma provides her client a break when she earns 5 tokens. She also gives her client two bonus tokens before DTT starts, which represents extra minutes on break. Emma uses an FR3 schedule and a response cost. What type of procedure is a response cost?
How come it is negative punishment if client getting tokens.
Thank you.
A response cost is a form of negative punishment. It involves the removal of a reinforcer (such as tokens) contingent on an undesired behavior, decreasing the likelihood of that behavior occurring in the future. In Emma’s case, if the client loses tokens due to inappropriate behavior, this represents a response cost procedure.
For “Money, tokens, and praise are all examples of what type of reinforcement?” why wouldn’t they also be examples of positive reinforcement? (I would say that they’re both positive and conditioned, so either answer is correct – obviously you could also take them away, such as taking away tokens, but wouldn’t that make it become a punishment procedure instead?)
Hi Amanda,
It would be easy for us to explain in better way if you can provide the full question here.
In this question, we need to define to the parent so we will use easy language
Hi Saima,
Please write the whole question so that we can clear your doubt.
Thank you
I love these practice questions. Whatever I don’t know I write down and look it up for better understanding
by search I mean when I use google with the words in answer C
How would you explain shaping to a parent who knows nothing about applied behavior analysis?
A. Each time your child gets closer to the final behavior, we will reward them.
B. Positive reinforcement will be used every time your child gets closer to the terminal behavior.
C. For each successive approximation , your child will receive a reward.
D. We picked a terminal behavior and will be reinforcing successive approximations towards that behavior.
Is not answer A and answer C the same when describing what shaping is? Successive approximation implies that when the child gets closer to the correct behavior, they are rewarded. When I search answer C on its own, I get results about shaping behavior. I put answer C but it says only answer A is correct. What is the difference as they both seem correct in the context of this question.
They are all correct descriptions, but answer A uses the simplest language, so it is the easiest explanation to understand. The goal here is to explain the concept for people without knowledge of ABA principles.
I don’t see my result after taking the test.

Is FR1 schedule same as continue reinforcement? Where is the difference.
Yes, a Fixed Ratio 1 (FR1) schedule is the same as continuous reinforcement (CRF). In both cases, reinforcement is provided after every occurrence of the target behavior.
Last time, I failed in RBT exam. But, now I’m scoring 70+ in Mock Tests. Do I need to study whole Task List again or just practice test is enough?
Hi Rachel,
Your score is good. All you need is Practice, Practice, Practice! Access more free practice tests on our homepage.
All the best!
. Jessica is working with her client on a new skill involving one-word minds, explicitly requesting “GO” when the client wants to leave a room. Jessica provides reinforcement every time the client emits the target response. What is Jessica implementing?
Fixed Interval Reinforcement
Continuous Reinforcement
Discontinuous reinforcement
Both A and B
— Lists Both A and B as correct, but I don’t see how this could be considered an interval schedule without some defined time interval
In this scenario, she is providing reinforcement (positive reinforcement) every time the client emits the target response (“GO”). Continuous reinforcement involves reinforcing the desired behavior each time it occurs, which is essential for teaching new skills.
So, the correct answer is Continuous Reinforcement.
no logro llegar a la pregunta 75 me las quitan antes y no me dice la respuesta correcta
This threw me at first too. Until I thoroughly read the question and read that it dies mention time. It’s tricky.
