The RBT Competency Assessment in 2026: All 19 Tasks, Explained
Nineteen tasks, four sections, and one signature standing between you and your RBT application. Here is exactly what is on the 2026 form — and what your assessor is looking for on each task.
If you have just finished your 40-hour training, the RBT competency assessment is the last thing standing between you and your certification application. It is not a test you sit alone at a computer — it is a hands-on skills check where a qualified assessor watches you perform each task and initials a box when you do it competently.
This guide is built directly from the BACB’s own assessment form, the version that took effect January 1, 2026. A lot of what you will find elsewhere still describes the older 20-task version, or lists domain names that no longer exist on the form. Everything below matches the document your assessor will actually be holding.
The short version
19 tasks. Four sections. A BCBA or BCaBA who has completed the 8-hour supervision training signs it off.
Three tasks from the Skill Acquisition and Behavior Reduction section must be done with a real client;
most of the rest can be role-played, and five are interview questions. You must be assessed as competent on
all 19 — there is no partial pass — and you can be reassessed as many times as it takes.
What the RBT competency assessment actually is
The BACB calls it the RBT Initial Competency Assessment. It exists to confirm that you can perform the core tasks of the job, not just answer questions about them. Your assessor gives you an opportunity to perform each of the 19 tasks and judges whether you did it competently.
Three things surprise most candidates:
- It is not pass/fail in the way an exam is. If you do not demonstrate competence on a task, your assessor can give you corrective feedback and assess that task again on another day. This repeats until you get it. The one restriction is that corrective feedback cannot be given during the final assessment of a task.
- It does not have to happen in one sitting. The assessment may be conducted over one or more sessions, in person, live over the internet, or through recorded video made specifically for the assessment.
- Your own supervisor usually runs it. In most cases the BCBA at the agency that hired you is your assessor, and the assessment happens during ordinary work sessions.
Who is allowed to assess you
The rules here are stricter than most summaries let on, and they are worth checking before you schedule anything — an assessment signed by the wrong person does not count.
| Role | Requirements |
|---|---|
| Responsible assessor | An active BCaBA or BCBA who has completed the 8-hour supervision training. They oversee the whole assessment, sign it, keep the records, and are accountable for its quality even if someone else conducted parts of it. |
| Assistant assessor (optional) | Holds an active RBT certification or higher and has demonstrated proficiency in the material through direct observation. The responsible assessor can delegate some or all of the assessment, and can use more than one assistant. |
| Everyone involved | Must be employed at — or have a contractual relationship with — the same organization as you. That organization must also be the entity providing services to the client involved in the assessment. |
| Hard disqualifiers | Your assessor may not be related to you, subordinate to you, or employed by you. Paying someone for assessment services does not count as employing them. |
A common question, answered
Yes — the person who delivered your 40-hour training is allowed to be your assessor. The BACB says so
explicitly.
Timing: the 90-day rule
Two constraints bracket the assessment:
- It must be completed after your 40-hour training is finished.
- It cannot be completed more than 90 days before you submit your RBT certification application.
That second one catches people out. If you finish your assessment and then take four months to get your application together, the assessment has aged out and has to be redone. Treat the signed form as a 90-day clock and submit your application inside it.
The three assessment types
Each task on the form specifies which methods are permitted. You do not get to choose freely — the form does.
| Type | What happens | Where it is allowed |
|---|---|---|
| With a Client | Your assessor observes you performing the task with a client who is receiving behavior-analytic services. | Permitted on tasks 1–15. Required for three of tasks 6–14. |
| Role-Play | Your assessor observes you performing the task with another person acting as the client. Used when circumstances do not allow a real client. | Permitted on tasks 1–15. |
| Interview | A live interview, in person or online, where you describe the concept and give examples and non-examples. Questions can be tailored to your actual clients and workplace. | Only on tasks 13, 15, and 16–19. |
You cannot talk your way through the hands-on tasks
Tasks 1–12 and 14 have no interview option at all. Measurement, preference assessments, ABC data, DTT,
chaining, shaping, prompting, token systems — all of them must be performed, either with a client or in
role-play. If a study guide tells you that you can simply explain these, it is describing an older form.
All 19 tasks on the 2026 form
Below is every task, in order, with the assessment types the form permits and what your assessor is likely to be looking for. Task names and descriptions are quoted from the BACB form; the guidance under each is ours.
Measurement (Tasks 1–3)
1Continuous Measurement
Implement continuous measurement (e.g., frequency, duration, latency, IRT).
With a ClientRole-Play
What the assessor is watching for: Say out loud which dimension you're measuring and why: frequency for discrete countable responses, duration for how long, latency for time from SD to response, IRT for time between responses. Have your timer or counter in hand before the trial starts.
2Discontinuous Measurement
Implement discontinuous measurement procedures (e.g., partial and whole interval, momentary time sampling).
With a ClientRole-Play
What the assessor is watching for: Set the interval length first and hold to it. Score partial interval if the behavior occurred at any point, whole interval only if it occurred throughout, and MTS only at the moment the interval ends. Knowing that partial interval overestimates and whole interval underestimates is a common follow-up question.
3Data and Graphs
Enter data and update graphs.
With a ClientRole-Play
What the assessor is watching for: Transfer raw data accurately, label both axes, keep the scale consistent, draw a phase-change line where the condition changed, and do not connect data points across that line. Sloppy axis labels are the most common reason this one gets re-run.
Assessment (Tasks 4–5)
4Preference Assessments
Conduct preference assessments.
With a ClientRole-Play
What the assessor is watching for: Name the format you're running (free operant, single stimulus, paired stimulus, MSWO, MSWOR) and follow it exactly. Rotate array positions between trials, record every selection, and produce a ranking at the end rather than a vague impression.
5ABC Data
Collect ABC data.
With a ClientRole-Play
What the assessor is watching for: Record only what is observable. The antecedent is what happened immediately before, the behavior is an operational definition, and the consequence is what happened immediately after. Keep hypotheses about function out of the columns — that inference belongs to your BCBA.
Skill Acquisition and Behavior Reduction (Tasks 6–14)
The three-client rule lives hereThree of tasks 6–14 must be demonstrated with a client. You pick which three, in consultation with your assessor. Every other task in this section can be done by role-play.
6Discrete-Trial Teaching
Implement discrete-trial teaching procedures.
With a ClientRole-Play
What the assessor is watching for: Run the full sequence cleanly: SD once (no repeating), prompt at the programmed level, allow the response interval, deliver the consequence immediately, then the inter-trial interval. Record trial by trial as you go, not from memory afterwards.
7Naturalistic Teaching
Implement naturalistic teaching procedures (e.g., incidental teaching).
With a ClientRole-Play
What the assessor is watching for: Follow the learner's lead, capture or contrive the motivating operation, embed the target into the activity, and reinforce with the natural reinforcer the learner was already after. Assessors watch for whether you waited for the learner to initiate.
8Chaining
Implement task analyzed chaining procedures.
With a ClientRole-Play
What the assessor is watching for: Bring the written task analysis and use it. State whether you're running forward chaining, backward chaining, or total task, prompt at the correct step, and don't quietly skip steps the learner finds hard.
9Shaping
Implement shaping procedures.
With a ClientRole-Play
What the assessor is watching for: Define the terminal behavior first, then reinforce successive approximations toward it. Only raise the criterion once the current approximation is stable, and be ready to explain why you didn't jump straight to the end goal.
10Discrimination Training
Implement discrimination training.
With a ClientRole-Play
What the assessor is watching for: Reinforce responding in the presence of the SD and withhold it for the S-delta. Rotate the position of items in the array so the learner can't pass by position, and run to the mastery criterion in the program rather than stopping early.
11Prompting
Implement prompt and prompt fading procedures.
With a ClientRole-Play
What the assessor is watching for: Name the hierarchy you're using — most-to-least, least-to-most, or time delay — and fade systematically. Watch your own inadvertent prompts: eye gaze, leaning toward the correct card, or positioning it closer. The goal you're being scored on is transfer to independent responding.
12Token Systems
Implement token systems.
With a ClientRole-Play
What the assessor is watching for: Be able to state what earns a token, the exchange ratio, and the backup reinforcers. Deliver tokens immediately and pair them with behavior-specific praise, and actually run the exchange rather than describing it.
13Crisis/Emergency
Implement crisis/emergency procedures according to protocol.
With a ClientRole-PlayInterview
What the assessor is watching for: This one may be assessed by interview. Describe your organization's written protocol, not a generic answer: when you call for help, how you document and report the incident, and the fact that RBTs implement crisis protocols but never design or modify them.
14Antecedent Interventions or Differential Reinforcement or Extinction
Demonstrate one of: implement interventions based on modification of antecedents (e.g., motivating/establishing operations, discriminative stimuli); implement differential reinforcement procedures (e.g., DRA, DRO); or implement extinction procedures.
With a ClientRole-Play
What the assessor is watching for: Pick the one you genuinely run every day — you choose, not the assessor. If you choose extinction, be ready to name the maintaining reinforcer you're withholding and to mention the extinction burst, because that follow-up question is almost automatic.
Professionalism and Requirements (Tasks 15–19)
15Session Notes
Generate objective session notes by describing what occurred during sessions.
With a ClientRole-PlayInterview
What the assessor is watching for: Write what is observable and measurable: what programs ran, what the data showed, what happened. Strip out diagnostic language, opinion, and anything interpretive. “Client was defiant” fails; “client did not respond to 4 of 10 SDs within 5 seconds” passes.
16Client Dignity
Provide examples of how to maintain client dignity.
Interview
What the assessor is watching for: Interview only, and generic answers stall here. Give concrete examples: privacy during toileting or personal care, age-appropriate materials and language, offering choices, speaking to the client rather than about them in front of them, and honoring withdrawal of assent.
17Professional Boundaries
Provide examples of how to maintain professional boundaries.
Interview
What the assessor is watching for: Interview only. Name real situations: declining gifts, avoiding dual relationships, not connecting with families on social media, not babysitting a client outside of sessions, and redirecting clinical questions from parents to your supervising BCBA.
18Supervision Requirements
Describe BACB Supervision Standards for RBTs.
Interview
What the assessor is watching for: Interview only, and this is the most commonly failed task because it's memorization. RBTs must be supervised for at least 5% of the hours they spend delivering behavior-analytic services in a calendar month, including two face-to-face contacts, at least one of which is an individual meeting. Know your supervisor's name and credential too.
19Clinical Direction
Describe at least one situation in which you would seek clinical direction from your supervisor.
Interview
What the assessor is watching for: Interview only. Have one specific scenario ready rather than a principle: a new behavior you haven't seen before, a protocol that isn't producing change, a safety concern, or a parent asking you something outside your scope.
How the paperwork works
As you demonstrate each task competently, your assessor initials the box next to it and marks which assessment type was used. Once all 19 are done, the responsible assessor signs and dates the final attestation. You then submit the completed form with your certification application.
Use the BACB’s form, not your agency’s version
The BACB states plainly that non-BACB forms will not be accepted, and that incomplete documents will be
rejected. Some agencies keep an internal tracking sheet, which is fine as a working document — but the
thing you submit has to be the BACB’s own Initial Competency Assessment form. Your assessor is also
required to retain documentation for a minimum of seven years.
If you want a working document to track your own progress before the official form gets signed, we built one for exactly that:
Open the free 19-task competency tracker →What happens after you pass
The competency assessment is step three of four. Once it is signed you can submit your application, and once your application is approved you sit the RBT examination — 85 questions in 90 minutes at a testing centre. They are genuinely different challenges, and the assessment being straightforward is no signal that the exam will be. We break down the difference in competency assessment vs. RBT exam.

How many tasks are on the RBT competency assessment in 2026?
Nineteen. The form effective January 1, 2026 has 19 numbered tasks across four sections: Measurement (tasks 1–3), Assessment (tasks 4–5), Skill Acquisition and Behavior Reduction (tasks 6–14), and Professionalism and Requirements (tasks 15–19). Older guides describing 20 tasks are referring to the previous version of the form.
Can you fail the RBT competency assessment?
Not in the sense of being permanently failed. If you do not demonstrate competence on a task, your assessor may give you corrective feedback and assess that task again on another day, repeating until you demonstrate competence. The only restriction is that corrective feedback cannot be delivered during the final assessment of a task. You must be competent on all 19 tasks before the form can be signed.
Who can conduct the RBT competency assessment?
The responsible assessor must be an actively certified BCaBA or BCBA who has completed the 8-hour supervision training. They may delegate parts of the assessment to assistant assessors who hold an active RBT certification or higher. The assessor cannot be related to you, subordinate to you, or employed by you, and everyone involved must be at the same organization that is providing services to the client.
How many tasks have to be done with a real client?
Three. Specifically, three of tasks 6 through 14 in the Skill Acquisition and Behavior Reduction section must be demonstrated with a client who is receiving behavior-analytic services. Which three is up to you and your assessor. The remaining tasks in that section can be completed by role-play.
How long does the RBT competency assessment take?
There is no fixed length, and it does not have to happen in one sitting. The BACB allows the assessment to be conducted over one or more sessions. In practice many agencies fold it into ordinary work sessions across a week or two. It can be done in person, live over the internet, or through video recorded specifically for the assessment.
How long is the competency assessment valid before I apply?
It cannot be completed more than 90 days before you submit your RBT certification application. If more than 90 days pass between finishing the assessment and submitting your application, you will need to complete the assessment again.
Do I have to use the BACB's form?
Yes. The BACB states that non-BACB forms will not be accepted and that incomplete documents will not be considered. An agency's internal tracker or a personal checklist is useful for preparation, but the document submitted with your application must be the BACB's own Initial Competency Assessment form, signed by your responsible assessor.
Is the competency assessment the same as the RBT exam?
No. The competency assessment is a hands-on skills check conducted by your assessor before you apply, covering 19 tasks. The RBT examination is a separate 85-question multiple-choice test taken at a testing centre after your application is approved. Passing one says nothing about passing the other.
