RBT Interview Questions: 30+ Questions with Answers
ABA agencies are actively hiring RBTs, and if you have your certification (or are about to), you will be interviewing soon. This guide covers the questions hiring managers and clinical directors actually ask, with sample answers that demonstrate your knowledge and professionalism.
Before your interview: Research the agency (client population, size, treatment philosophy). Review the RBT Task List domains. Be ready to discuss your 40-hour training, any hands-on experience, and why you chose ABA.
General Questions
1. Why do you want to work in ABA?
Be genuine. Talk about what drew you to behavior analysis specifically, not just "helping people." Mention something concrete: a personal experience, a course that changed your perspective, or an observation that made you want to pursue this field. Hiring managers hear "I want to help children" fifty times a week. What makes your motivation specific?
2. What do you know about our agency?
Research before the interview. Know their client population (children, adults, or both), their service model (in-home, center, school), their size, and anything notable from their website or social media. Mention something specific. "I saw that you specialize in early intervention for children under 3" is better than "I know you do ABA therapy."
3. What relevant experience do you have?
If you have direct ABA experience, describe it. If this is your first ABA role, connect your other experience: working with children (daycare, tutoring, camp), working with individuals with disabilities (group homes, special education), healthcare experience, or even customer service (demonstrates patience, communication, and adaptability). Your 40-hour training course is relevant experience.
4. What does an RBT do?
Describe the role clearly: implement behavior analysis treatment plans under the supervision of a BCBA, collect data on client behavior, run skill acquisition programs, implement behavior reduction strategies, and document session activities. Emphasize that you work under supervision and do not design or modify treatment plans independently.
Clinical Knowledge Questions
5. What are the four functions of behavior?
Attention, escape, access to tangibles, and automatic (sensory) reinforcement. Every behavior serves at least one function. Understanding the function is essential because the intervention must match the function. A behavior maintained by escape requires a different approach than one maintained by attention.
6. What is the difference between positive and negative reinforcement?
Positive reinforcement adds something desirable after a behavior to increase it (giving a sticker after a correct response). Negative reinforcement removes something aversive after a behavior to increase it (ending a difficult task when the child asks for a break). Both increase behavior. The difference is adding versus removing. Neither word means "good" or "bad."
7. How would you handle a client engaging in self-injurious behavior?
Follow the behavior intervention plan (BIP) written by the supervising BCBA. Ensure client safety first. Implement the specific procedures outlined in the plan. Collect data. If there is no BIP for this behavior, or if the behavior escalates beyond what the plan covers, contact your supervisor immediately. Do not improvise interventions for dangerous behavior.
Hiring managers want to hear that you follow the plan and contact your supervisor when needed, not that you would create your own solution on the spot.
8. Describe a discrete trial.
A discrete trial has four components: the discriminative stimulus (SD, the instruction or cue), the learner's response, the consequence (reinforcement for correct, correction for incorrect), and the inter-trial interval (a brief pause before the next trial). For example: "Touch red" (SD), child touches the red card (response), "Great job!" plus a token (consequence), 3-second pause (ITI).
9. What is pairing and why is it important?
Pairing is the process of building rapport with a client by associating yourself with positive experiences. Before you can effectively teach or implement programs, the client needs to view you as someone they want to be around. You do this by following the client's lead, offering preferred items and activities, making no demands initially, and gradually introducing instructional demands as the relationship builds.
10. What is the difference between DTT and NET?
Discrete Trial Teaching (DTT) is structured, therapist-led, and happens at a table or designated area. The therapist controls the materials and pacing. Natural Environment Teaching (NET) happens in the client's natural environment during play or daily activities. The therapist follows the client's motivation and creates teaching opportunities within naturally occurring situations. Both are effective. Many programs use a combination.
11. What types of data collection have you used?
Describe the specific types: frequency (counting occurrences), duration (timing how long a behavior lasts), latency (time between instruction and response), interval recording (partial, whole, or momentary time sampling), and trial-by-trial data for skill acquisition programs. If you have hands-on experience, mention which methods you used most and with what types of programs.
Behavioral Scenario Questions
12. A child has a tantrum in a grocery store during a community outing. What do you do?
Ensure safety first (remove the child from any dangerous situation). Implement the behavior plan. If the function is escape (the child wants to leave the store), do not leave immediately, as that reinforces the tantrum. If the function is access (the child wants a specific item), do not provide the item during the tantrum. Stay calm, follow the plan, and collect data. Debrief with your supervisor afterward.
13. A client is not responding to the reinforcer. What do you do?
Check whether the reinforcer is still motivating (preferences change). Run a quick preference assessment. Try a different reinforcer from the approved list. Verify you are delivering reinforcement immediately after the target behavior (timing matters). If nothing works, document what happened and discuss with your BCBA. They may need to reassess the reinforcer or adjust the program.
14. A parent asks you to change the treatment plan. How do you respond?
Thank them for the feedback. Explain that treatment plan modifications are made by the supervising BCBA, and that you will relay their concern to your supervisor. Do not agree to modify the plan yourself. RBTs implement plans, they do not modify them. This is a scope of practice boundary. Follow up by informing your BCBA about the parent's request.
This question tests whether you understand your scope of practice. The correct answer always routes clinical decisions to the BCBA.
15. How do you maintain professional boundaries with a client's family?
Be friendly but professional. Do not share personal contact information (use work channels only). Do not accept gifts of significant value. Do not engage in personal relationships with family members. Do not discuss other clients. Do not provide clinical opinions or advice outside your scope. If a family member asks you a clinical question, redirect them to the BCBA.
Ethics Questions
16. You see a coworker not following a client's behavior plan. What do you do?
First, consider whether it might be a misunderstanding (maybe the plan was updated and they were not informed). If it appears intentional, discuss it privately with the coworker first. If the behavior continues, report it to your supervisor. Treatment integrity matters. A behavior plan only works if it is implemented consistently by everyone on the team.
17. A parent tells you they are using a non-evidence-based treatment. What do you say?
Listen respectfully. Do not criticize or dismiss their choice. RBTs do not provide clinical advice on treatments outside ABA. Let your BCBA know about the conversation so they can address it during the next parent meeting with appropriate clinical guidance.
18. What would you do if you suspected child abuse or neglect?
Follow mandated reporting requirements. In most states, RBTs and behavior technicians are mandated reporters. Report your concerns to the appropriate child protective services agency immediately. Also inform your supervisor. Do not investigate on your own. Do not confront the family. Document what you observed factually.
Professional Development Questions
19. How do you handle constructive feedback?
Welcome it. Supervision feedback is how you improve as a clinician. When you receive feedback, listen actively, ask clarifying questions if needed, and implement the changes in your next session. If you disagree, discuss your perspective respectfully, but ultimately defer to your supervisor's clinical judgment. The ability to accept and apply feedback is one of the most important traits in an RBT.
20. Where do you see yourself in 3 to 5 years?
Be honest about your goals. If you plan to pursue the BCaBA or BCBA, say so. Agencies value RBTs who are investing in the field long-term. If you are not sure yet, say that you are focused on becoming an excellent RBT first and are open to growth opportunities. Avoid saying "I want your job" or "just passing through."
21. Are you aware of the new 12-PDU requirement?
Yes. As of January 1, 2026, RBTs need 12 Professional Development Units per 2-year certification cycle. I am already planning for this requirement. (Mentioning this shows awareness of the field and forward-thinking.)
Many candidates will not know about PDUs yet. Knowing about the new 12-PDU requirement shows you stay informed about BACB changes. It is a differentiator. Learn more about PDU requirements.
Questions to Ask the Interviewer
Always ask questions. It shows engagement and helps you evaluate whether this agency is right for you.
- "What does supervision look like here?" (How often? Individual or group? Direct observation included?)
- "What is the typical caseload for an RBT?" (How many clients? How many hours per week?)
- "How does the agency support professional development?" (Training budget? Tuition reimbursement? Internal PD sessions?)
- "What client population does this role primarily serve?" (Age range? Diagnoses? Severity levels?)
- "What does the first 30 days look like for a new RBT?" (Onboarding? Shadowing? Gradual caseload?)
- "Do you have a plan for the new 12-PDU requirement?" (Shows forward-thinking. Evaluates whether the agency is prepared.)
- "What is the team culture like?" (Collaboration? Support? Turnover?)
