Question 1

An RBT is teaching a learner to wash hands using a task-analyzed chain. After turning on the water, the learner immediately reaches for a paper towel, skipping the steps of wetting hands and applying soap. What should the RBT do?

▸Show the answer — and why each of the other three is wrong

B is correct.When teaching a behavior chain using a task analysis, skipping a step must be interrupted immediately to prevent the learner from practicing an improper sequence or accessing reinforcement for an incorrect chain. The technician provides the predetermined prompt for the correct next step. Allowing the learner to dry hands lets the learner practice an incorrect behavioral chain and contact inappropriate completion. Turning off the water and restarting from the beginning can turn chaining into an overly punitive procedure and does not teach correct step progression. Completing missed steps while the learner continues reinforces skipping required components.

Question 2

A client begins screaming and throwing materials whenever difficult math worksheets are presented during instruction. The supervising BCBA determines that this problem behavior is maintained by escape from demands. Why is time-out contraindicated for this behavior?

▸Show the answer — and why each of the other three is wrong

D is correct.Time-out from positive reinforcement involves removing access to reinforcing activities. When a behavior is maintained by escape or task avoidance, removing the client from the instructional context fulfills the client's motivation to avoid the task, functionally providing negative reinforcement rather than punishment. Believing that time-out requires too much physical guidance confuses time-out with physical restraint or overcorrection. Asserting that time-out can only be used after extinction has failed is incorrect because treatment selection is guided by function and ethics, not a rigid sequential rule. Finally, time-out is not strictly prohibited for all school-age clients, though it must be used cautiously and ethically under supervisor direction.

Question 3

An RBT reviews a client's baseline graph with the supervising BCBA. Over the past five consecutive sessions, data points show minimal variability with neither an upward nor a downward slope. Which pattern of responding is displayed on the graph?

▸Show the answer — and why each of the other three is wrong

A is correct.Steady state responding occurs when repeated measurement reveals a stable pattern with minimal variability and no clear upward or downward trend. An ascending trend describes data points showing a consistent upward trajectory over time, which is absent here. High variability indicates wide fluctuations and bounce between data points across consecutive sessions, whereas this graph demonstrates minimal variability. An extinction burst involves a temporary, dramatic increase in the frequency, duration, or intensity of a target behavior following the removal of reinforcement, rather than stable, low-variability responding. Therefore, steady state is the correct term for graphed data showing consistent rates without a slope.

Question 4

An RBT finishes an in-home session and sits in a crowded coffee shop while finishing documentation. The RBT considers using voice-to-text dictation on a tablet to complete session notes quickly. What should the RBT do?

▸Show the answer — and why each of the other three is wrong

C is correct.Typing notes manually protects client confidentiality. RBTs must comply with requirements for protecting confidential information and avoid dictating clinical notes aloud where bystanders could overhear details. Dictating quietly without a last name or using initials still risks disclosing identifiable clinical details and session activities to nearby patrons. Moving to an outdoor patio does not resolve the issue because bystanders can still overhear spoken details in public dining spaces. The technician must ensure that private health information cannot be overheard by anyone in the vicinity.

Question 5

At the conclusion of a session, a caregiver asks the RBT how many more months of ABA services the client will need before being discharged from the clinic. What is the BEST response for the RBT to give?

▸Show the answer — and why each of the other three is wrong

B is correct.Determining discharge criteria, estimated timelines, and service continuation falls solely within the scope of practice of the supervising BCBA. The RBT must direct the caregiver to speak with the BCBA regarding discharge planning. Providing an estimated timeline oversteps the technician's scope and provides unverified clinical projections. Explaining general discharge criteria or attempting to interpret clinical criteria for the family is an assessment and planning task reserved for the supervisor. Reviewing mastered goals to help the caregiver predict duration encourages family speculation without supervisory oversight.

RBT practice — frequently asked questions

What is the RBT exam?
The Registered Behavior Technician (RBT) exam is the certification exam of the Behavior Analyst Certification Board (BACB) for behavior technicians, who deliver applied behavior analysis services under supervision.
How many questions are on the RBT exam?
Eighty-five multiple-choice questions with four options each: 75 are scored and 10 are unscored. You cannot tell which are unscored, so treat every question as if it counts.
How long is the RBT exam?
You have 90 minutes for the 85 questions — a little over a minute per question. Our 75-question practice tests run at that same pace: 79 minutes.
What does the RBT exam cover?
Six content areas from the BACB RBT Test Content Outline (3rd ed., effective January 1, 2026). Of the 75 scored questions: Data Collection and Graphing 13, Behavior Assessment 8, Behavior Acquisition 19, Behavior Reduction 14, Documentation and Reporting 10, and Ethics 11.
What score do I need to pass the RBT exam?
The BACB reports a scaled score and does not publish a fixed passing percentage. Our readiness estimate uses 70% as a practical target — treat it as a guide, not the official cut score.
How should I practice for the RBT exam?
Take full 75-question practice tests at real-exam pace, then read the explanation for every question you missed — and for the ones you guessed. Weight your practice toward Behavior Acquisition and Behavior Reduction, the two largest areas.
