What Is the RBT Competency Assessment?
The RBT competency assessment is one required component to become a Registered Behavior Technician® (RBT®) through the Behavior Analyst Certification Board® (BACB®). The purpose of the competency assessment is to demonstrate that you understand and can accurately perform the tasks required of an RBT.
What Items Are Assessed on the RBT Competency Assessment?
The RBT competency assessment covers 19 task items across four domains: Measurement, Assessment, Skill Acquisition and Behavior Reduction, and Professionalism and Requirements.
Measurement
Three of the tasks in the competency assessment cover measurement. For each of these tasks, you will need to demonstrate with a client through role-play or interview.
Measurement competencies assessed include:
- Continuous measurement (i.e., frequency, duration, etc.)
- Discontinuous measurement (i.e., partial and full interval recording)
- Enter and update graphs
Assessment
Two tasks are assessed under the assessment domain. For each of these, you will need to either demonstrate them with a client or via role-play with your assessor.
Assessment competencies assessed include:
- Preference assessments
- ABC data
Skill Acquisition and Behavior Reduction?
Nine tasks are assessed under the skill acquisition and behavior reduction domain. These tasks make up a large portion of an RBTs typical job duties. At least three of these tasks must be demonstrated with a client. The remaining tasks can be demonstrated via role-play with your assessor.
Skill Acquisition and Behavior Reduction competencies assessed include:
- Discrete trial teaching (DTT)
- Naturalistic teaching
- Chaining
- Shaping
- Discrimination training
- Prompting
- Token systems
- Crisis procedures
- Antecedent interventions, differential reinforcement, or extinction
For the last task under Skill Acquisition and Behavior Reduction, you only need to demonstrate one of the three, not all of them. Your assessor may instruct you on which one, or they may allow you to choose. However, it’s a good idea to be prepared to demonstrate any of those.
Professionalism and Requirements
The final section in the RBT competency assessment is Professionalism and Requirements, which covers five tasks. Most of these tasks are completed in an interview format, with the exception of session notes. Writing objective session notes can be demonstrated with a client or via role-play.
Professionalism and Requirements competencies assessed include:
- Session notes
- Client dignity
- Professional boundaries
- Supervision requirements
- Clinical direction
Assessment Structure Details to Know
Location
The location of your RBT competency assessment may vary. Because you need to demonstrate at least three tasks with a client, your competency assessment is likely to be completed in a client’s home, in a clinic, or at a school. Some people also complete their assessment, or portions of their assessment, remotely via two-way video communication (i.e., Zoom).
Test Administration
A BCBA most often administers the competency assessment. Sometimes an assistant assessor will conduct the assessment under the supervision of a BCBA.
Competencies are evaluated in different ways. Some competencies are assessed by observing you perform them with a client. Others can be assessed via role-play with your assessor acting as the client. Some competencies are also completed via a live interview. A minimum of three tasks, all from the skill acquisition and behavior reduction domain, must be demonstrated with a client.
Documentation
Your assessor will document task completion via an initial competency assessment form. On this form, they will mark their initials under each task as they observe you demonstrate them accurately. In addition to their initials, they will check off the box that indicates whether the task was observed with a client, via role-play, or in an interview format. Once all competencies have been completed, your assessor will sign and date the final attestation. You will submit your completed assessment to the BACB when completing your exam application.
Time
Your competency assessment must be completed after your 40-hour training has been completed. You cannot complete your competency assessment more than 90 days before submitting your RBT certification application.
The amount of time a competency assessment takes can vary. However, it is most often completed in 1 to 3 hours. If you do not successfully complete all tasks on your competency assessment, another observation or meeting will be required to reassess those tasks.
What to Expect After the Competency Assessment
Upon demonstrating all 19 tasks in the competency assessment, your assessor will sign off on your assessment, confirming successful completion. The next step after the competency assessment is to prepare for the RBT certification exam.
The RBT exam is the final component required to become certified as a registered behavior technician.
