RBT Interview Questions for ABA Providers and Clinical Directors

This page is for the ABA provider, clinical director or BCBA hiring a registered behavior technician, not for candidates preparing for an interview. The RBT credential comes from the Behavior Analyst Certification Board (BACB), and an RBT always works under a qualified supervisor, so the interview does not need to test clinical design. It needs to find out two things: whether the candidate will run a plan exactly as written and record honest data, and whether they stay calm and kind when a session goes badly. Most other skills can be trained in the 40-hour course and in supervision.

What the RBT credential requires

Know the rules before you interview, because a candidate who is “in training” and one who is certified are different hires. The RBT Handbook lists the eligibility requirements that must be met before applying:

• Age and education. At least 18 years old when the application is submitted, and “at least a high school-level education or the equivalent.”
• Background and abuse registry checks. Both must be passed no more than 180 days before paying for the application, and must be “comparable to those required for home health aides, child care professionals, and teachers in the community where you will provide services.” The BACB does not require fingerprinting, but notes that this “may vary by state and organization.”
• 40-hour training. Completed in no less than 5 days and no more than 180 days, to the RBT 2026 40-Hour Training Requirements. It may be offered by an employer, a university or an online program. The BACB does not provide the training.
• Initial Competency Assessment. Completed after the training and no more than 90 days before the application, with an assessor who may not be related to, subordinate to or employed by the applicant.
• Exam. 85 multiple-choice questions (75 scored, 10 unscored) in 90 minutes. Behavior acquisition accounts for 19 of the 75 scored questions.

After certification, the handbook requires ongoing supervision for “a minimum of 5% of the hours you spend providing behavior-analytic services each calendar month,” with at least two face-to-face, real-time contacts a month, and the supervisor must observe the RBT providing services in at least one of them. RBTs without a qualified supervisor on record are considered inactive and “may not bill, practice, or represent themselves as active RBTs.” The BACB is also moving RBTs from annual recertification to a two-year cycle with 12 hours of professional development; the handbook explains how the 2026 transition works.

In practice: verify a certified candidate on the BACB Certificant Registry before the interview, and if you hire people to put through the 40-hour training yourself, say so in the ad and plan the supervision hours before they start.

Registered behavior technician job description

If the posting is not written yet, settle what the job actually is first. An RBT job description, in plain terms:

• Delivers one-to-one ABA sessions following the treatment plan written by the supervising BCBA or BCaBA, in a clinic, the client's home, a school or the community.
• Runs the procedures the supervisor assigns. The handbook's examples of appropriate RBT activities are “conducting preference assessments, implementing discrete-trial teaching procedures, and generating session notes, among others.”
• Collects and records data every session, and writes session notes that can stand up to a payer audit.
• Carries out behavior reduction plans as written, including any crisis or safety procedures the organization has trained.
• Attends supervision and acts on feedback, and follows the RBT Ethics Code (2.0).
• Communicates with caregivers and staff within the limits set by the supervisor.

Requirements to list: the BACB eligibility items above (or “we will pay for and schedule your 40-hour training”), reliable transportation if sessions are in homes or schools, and the hours you actually need. Many ABA sessions fall after school, so state whether the role is afternoons and evenings. The closest page we have for the posting itself is the direct support professional job description; adapt its structure and use the list above for duties.

Ten RBT interview questions worth asking

Ask the same questions of every candidate and score as you go. If you can, add a short role-play with the supervising BCBA acting as the client; ten minutes of a mock discrete-trial run shows more than any answer.

“Your client does something you do not have a plan for. What do you do in that session, and afterward?”

This is the scope question. A strong answer keeps everyone safe, follows any general procedures the organization has trained, records exactly what happened, and contacts the supervisor. It does not invent a new intervention. A weak answer describes making something up on the spot and carrying on with it next session.

“Walk me through how you would run a discrete trial.”

For certified candidates and trainees who have finished the 40-hour course. Listen for the parts in order: getting attention, a clear instruction, a prompt if the plan calls for one, the response, the consequence, recording, and a short pause before the next trial. Candidates who can explain why the prompt fades over time understand what they are doing. Vague answers about “teaching skills through play” are not enough on their own.

“You forgot to take data for the last 15 minutes of a session. What goes in your notes?”

This one tests honesty, and it matters for billing as much as for the client. The strong answer is simple: record what you have, note the gap, tell the supervisor. Any answer that involves estimating or filling in the missing data is a serious red flag.

“A parent asks you to skip the program the BCBA set and just work on potty training today. What do you say?”

Caregivers talk to the RBT far more than to the supervisor. A strong candidate is warm with the parent, explains that changes to the plan come from the supervisor, and passes the request on the same day. A weak one either agrees to keep the family happy or brushes the parent off.

“Tell me about a time someone was aggressive toward you, at work or elsewhere. How did you respond?”

Many clients hit, bite, scratch or run. You need someone who stays calm, protects themselves and the client using the procedures they were trained on, and does not take it personally. Ask directly whether they are prepared for that. Candidates who have only imagined it are fine if they are honest; those who say it would never bother them usually have not seen it.

“What does your supervisor need to see from you in a supervision session?”

You are looking for someone who wants feedback. Good answers mention bringing data and questions, asking to be observed, and changing what they do after feedback. If a certified candidate cannot say how supervision worked at their last job, ask whether they had the required contacts; if they did not, that is useful information about their last employer, not necessarily about them.

“How would you keep a four-year-old engaged for a two-hour session?”

A practical question for pediatric caseloads. Strong answers mention preference assessments, varying tasks, pacing, reinforcement and breaks built into the plan. Weak answers rely only on personality: “kids love me.” Warmth matters, but it has to work inside the plan.

“You see another technician using a procedure that is not in the client's plan. What do you do?”

Tests whether the candidate will raise problems. The strong answer is to raise it with the supervisor promptly, and to act immediately if the client is at risk. Candidates who would stay quiet to avoid conflict will eventually stay quiet about their own mistakes too.

“What is your availability, and how will you get to sessions?”

Ask it plainly and ask it of everyone. Home and school sessions need a reliable car and a clean driving record if your policy requires one, and many families need after-school hours. A cancellation costs the client a session and costs you billable time, so a candidate whose availability does not match your caseload is not a fit, however good the rest of the interview was.

“Why this work, and why now?”

Many RBTs are students heading for graduate school or a BCBA credential; others come from childcare, teaching or caregiving. Neither is a problem. Listen for a real interest in the clients and an honest timeline. If a candidate plans to leave for graduate school in six months, you want to know that before you pay for their training.

Red flags

• Any willingness to estimate, backfill or “tidy up” data or session notes.
• Describing improvising interventions without telling a supervisor.
• Talking about past clients in identifiable detail.
• Describing clients with contempt, or treating challenging behavior as a personal insult.
• A certification that shows as inactive on the BACB registry with no clear explanation.

Not red flags: no experience when you run the 40-hour training yourself, being a student, and nerves. A reference check with a former supervisor adds what the interview cannot, and the post-offer screening required by the BACB and your state is covered in healthcare background checks.

Questions not to ask

ABA interviews often drift into personal territory because the work involves children and families. Do not ask about the candidate's own children, pregnancy or plans for a family, age, religion, health, disability, or national origin, and do not ask about a disability because of the physical side of the job. Ask whether they can perform the essential tasks, including the physical ones you describe, and about availability for your hours. See illegal interview questions for the full list.

How to score it

Rate each answer 1 to 4 immediately after it is given. Weight the scope question, the missed-data question and the aggression question most heavily; those predict whether a new RBT is safe to put in front of a client with only periodic supervision. If a BCBA and an HR lead both interview, score separately and compare. The interview scorecard template works for this.

Pay, and what it means for your offer

BLS does not have a separate Occupational Outlook Handbook profile for registered behavior technicians, so we do not quote a national wage figure here; use your local market and your payer rates. What candidates compare, beyond the hourly rate, is predictable: guaranteed hours when a client cancels, paid drive time and mileage between sessions, paid 40-hour training and exam fees for new hires, and a path to BCBA supervision hours. Put the ones you offer in the ad and say them again in the interview.
