Last updated: October 2026
The RBT Competency Assessment is the final hurdle between completing your 40-hour training and submitting your Registered Behavior Technician certification application to the Behavior Analyst Certification Board (BACB). It's a hands-on, performance-based assessment — not a written test — and the specific tasks, task numbers, and assessment methods changed with the BACB's 2026 packet, which took effect January 1, 2026.
If you were trained before 2026, or you're reading older guides online, you'll see references to six domains (labeled A through F) and anywhere from 20 to 25 numbered task IDs. That framework is no longer current. This guide uses the structure of the 2026 BACB RBT Initial Competency Assessment packet so what you prepare for is what you'll actually be assessed on.
What the Assessment Covers: Four Sections, 19 Tasks
The 2026 RBT Initial Competency Assessment, effective January 1, 2026, has 19 required tasks organized into four sections:
Measurement (tasks 1–3)
Assessment (tasks 4–5)
Skill Acquisition and Behavior Reduction (tasks 6–14)
Professionalism and Requirements (tasks 15–19)
Every task must be demonstrated using one of the approved methods specified in the packet — there are no optional items. Different tasks allow different methods (with a real client, by role-play, or by interview), and the packet is specific about which method applies to which task.
At-a-Glance Summary
Section | Tasks | Methods allowed |
|---|---|---|
1. Measurement | 1–3 | With client or role-play |
2. Assessment | 4–5 | With client or role-play |
3. Skill Acquisition and Behavior Reduction | 6–14 | With client or role-play (task 13 also allows interview; at least 3 of tasks 6–14 must be with a client) |
4. Professionalism and Requirements | 15–19 | Task 15: client, role-play, or interview. Tasks 16–19: interview only |
What Each Section Tests
Section 1: Measurement (Tasks 1–3)
This section covers how an RBT records what a client does — the raw observations that drive every clinical decision made by the supervising BCBA.
Task 1 — Continuous Measurement. Implement continuous measurement procedures (e.g., frequency, duration, latency, inter-response time).
Task 2 — Discontinuous Measurement. Implement discontinuous measurement procedures (e.g., partial and whole interval, momentary time sampling).
Task 3 — Data and Graphs. Enter data and update graphs.
Methods allowed: All three tasks can be demonstrated with a client or by role-play.
Section 2: Assessment (Tasks 4–5)
This section covers the two assessment procedures RBTs run under their BCBA's direction. RBTs do not design assessments; they implement them according to the plan.
Task 4 — Preference Assessments. Conduct preference assessments.
Task 5 — ABC Data. Collect ABC data.
Methods allowed: Both tasks can be demonstrated with a client or by role-play.
Section 3: Skill Acquisition and Behavior Reduction (Tasks 6–14)
This is the largest section — the core teaching and behavior intervention procedures RBTs implement day to day. It's also the section with the most structural variation: three of its tasks allow a wider range of methods, and one of the tasks (task 14) asks you to demonstrate one option from a short list.
Task 6 — Discrete-Trial Teaching. Implement discrete-trial teaching procedures.
Task 7 — Naturalistic Teaching. Implement naturalistic teaching procedures (e.g., incidental teaching).
Task 8 — Chaining. Implement task-analyzed chaining procedures.
Task 9 — Shaping. Implement shaping procedures.
Task 10 — Discrimination Training. Implement discrimination training.
Task 11 — Prompting. Implement prompt and prompt fading procedures.
Task 12 — Token Systems. Implement token systems.
Task 13 — Crisis/Emergency. Implement crisis/emergency procedures according to protocol.
Task 14 — Behavior Reduction (one of three options). Demonstrate one of the following: antecedent interventions (e.g., modifying motivating/establishing operations and discriminative stimuli); differential reinforcement procedures (e.g., DRA, DRO); or extinction procedures.
Methods allowed: Tasks 6–12 and task 14 are demonstrated with a client or by role-play. Task 13 (crisis/emergency) can be demonstrated with a client, by role-play, or by interview.
Important rule: The 2026 packet specifies that at least three of tasks 6–14 must be demonstrated with a real client — not by role-play. Coordinate with your assessor before the session so you know which three (or more) will be the client-based tasks.
Section 4: Professionalism and Requirements (Tasks 15–19)
This section covers the professional practice side of the RBT role — the parts that distinguish an RBT who understands their ethical and procedural obligations from one who only knows the procedures.
Task 15 — Session Notes. Generate objective session notes by describing what occurred during the session. Can be demonstrated with a client, by role-play, or by interview.
Task 16 — Client Dignity. Provide examples of how to maintain client dignity. Interview only.
Task 17 — Professional Boundaries. Provide examples of how to maintain professional boundaries. Interview only.
Task 18 — Supervision Requirements. Describe the BACB Supervision Standards for RBTs. Interview only.
Task 19 — Clinical Direction. Describe at least one situation in which you would seek clinical direction from your supervisor. Interview only.
Who Can Serve as the Assessor
The responsible assessor must be an active BCaBA, BCBA, or BCBA-D who has completed the 8-hour supervision training. An assistant assessor may be used alongside the responsible assessor; both are collectively referred to as the "assessor" in the packet.
Per the 2026 packet, the assessor may not be related to, subordinate to, or employed by the applicant during the assessment. Compensation paid to the assessor by the applicant for assessment services does not count as "employment" under this rule — so an RBT candidate can pay an independent assessor directly for the assessment itself without triggering the restriction.
The 40-hour trainer and the assessor can be the same person, as long as the relationship doesn't violate the "related to, subordinate to, or employed by" rule.
When the Assessment Must Be Completed
There is one timing rule that governs the whole process:
The RBT Initial Competency Assessment must be completed after the 40-hour training is complete, and no more than 90 days before you submit your RBT certification application to the BACB.
That's it. There is no separate "90 days from completion" rule — the clock begins when the assessment is completed and ends when your BACB application is submitted. If more than 90 days pass between completion and submission, the assessment is no longer valid for your application.
Worked Example: A Typical Assessment Session
Here's what a competently run assessment session often looks like in practice, for context.
Your assessor (a BCBA at the clinic where you'll be working, who is not your direct supervisor) schedules a 2–3 hour block with you and a consenting client. Before the session, you review the 2026 packet together, identify which tasks will be demonstrated with the client and which through role-play or interview, and clarify any procedural questions.
In the session, you move through several measurement tasks with the client (continuous and discontinuous measurement), then conduct a preference assessment and collect some ABC data. You run a short discrete-trial teaching sequence, demonstrate prompting with prompt fading, and implement one differential reinforcement procedure. Your assessor observes without intervening, taking notes on your performance.
If a task doesn't pass on first attempt, your assessor gives you corrective feedback and schedules the task for reassessment on a different day — not the same day. After all tasks are passed, your assessor completes and signs the packet, which becomes part of your BACB application.
Most candidates don't complete all 19 tasks in a single session — two or three focused sessions over a few days is more typical.
Common Fail Points
If you talk to assessors about where candidates lose points, five areas come up again and again:
Prompt fading (Task 11, Prompting). Candidates often prompt effectively but struggle to fade the prompt systematically. Over-prompting hides whether the learner has acquired the skill.
Extinction (Task 14, Behavior Reduction — one of the three options). Candidates sometimes slip and reinforce the exact behavior they're trying to put on extinction, especially under stress. Practice the full extinction procedure under supervision until it's automatic.
Session notes (Task 15, Session Notes). Objective, specific, and behavior-focused — not editorializing, not interpretive. Many candidates write what they think happened emotionally instead of what the learner did behaviorally.
Crisis protocol (Task 13, Crisis/Emergency). Candidates need to know their specific setting's protocol, not a generic one. If you don't know your clinic's crisis protocol in detail, learn it before the assessment.
Describing behavior in measurable terms (Tasks 1–2, Continuous and Discontinuous Measurement). Operational definitions are easy to understand and hard to execute. Practice turning everyday descriptions ("he was upset") into measurable language ("he engaged in vocal protest for 45 seconds") until it's second nature.
Prep Checklist
Before scheduling your assessment, verify each of the following:
Your 40-hour training is complete, with documentation
You've reviewed the 2026 BACB RBT Initial Competency Assessment packet in full
You know which of tasks 6–14 will be demonstrated with a real client (minimum three) and which with role-play
You've secured an assessor who is an active BCaBA, BCBA, or BCBA-D with the 8-hour supervision training complete
Your assessor is not related to you, is not your subordinate, and is not your employer (compensation for the assessment itself is fine)
You've secured client consent for the sessions where a real client will be involved
You've reviewed your 40-hour training notes, especially sections on measurement, prompting, and session documentation
You know your clinic's crisis/emergency protocol
You're ready to submit your BACB certification application within 90 days of the assessment being completed
After the Assessment
Once every task is passed, your assessor signs the packet and submits the signed documentation back to you. From that point forward, the 90-day window is active — you need to submit your BACB application before it closes.
If a task doesn't pass, your assessor provides corrective feedback and schedules reassessment on a different day. There is no limit on the number of times a task can be reassessed, but corrective feedback cannot be given during the final assessment of a task — the final attempt must be observed without live coaching.
Once you pass your assessment, submit your application, and receive your RBT certification, your ongoing obligations include:
Annual renewal through the BACB (fee, renewal competency assessment, and documentation of continuing requirements)
Ongoing supervision as defined in the current RBT Handbook (the "5% rule" — at least 5% of the hours you work providing behavior-analytic services must be supervised, plus the two monthly contacts required by the Handbook)
Compliance with the RBT Ethics Code and all applicable BACB standards

Frequently Asked Questions
How many tasks are on the 2026 RBT Competency Assessment?
The 2026 RBT Initial Competency Assessment (effective January 1, 2026) has 19 required tasks organized into 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).
Can all tasks be done through role-play?
No. The BACB 2026 packet requires that at least three of tasks 6–14 (Skill Acquisition and Behavior Reduction) be demonstrated with a real client, not by role-play. Tasks 16–19 (within Professionalism and Requirements) are interview only. Tasks 13 and 15 can be done with a client, by role-play, or by interview. You cannot choose role-play to avoid demonstrating a skill with a client.
What happens if I fail a task?
Your assessor provides corrective feedback and the task is scheduled for reassessment on a different day. There is no limit on the number of times a task can be reassessed. However, corrective feedback cannot be given during the final assessment of a task.
How long is the completed assessment valid?
The assessment must be completed after your 40-hour training and no more than 90 days before you submit your RBT certification application. The clock starts when the assessment is completed and ends when you submit the application.
Can my 40-hour trainer also be my assessor?
Yes. The BACB explicitly permits the 40-hour trainer and the assessor to be the same person. The assessor may not be related to, subordinate to, or employed by the applicant during the assessment — but compensation paid to the assessor by the applicant for assessment services does not count as employment under this rule.
Who qualifies as a responsible assessor?
An active BCaBA, BCBA, or BCBA-D who has completed the 8-hour supervision training. The assessor may not be related to, subordinate to, or employed by the applicant.
