Applied Behavior Analysis (ABA) is the science of using principles of learning and behavior to bring about meaningful, positive change. Registered Behavior Technicians (RBTs) are the front-line staff who deliver ABA services directly to clients, under the supervision of a BCBA or BCaBA.
How ABA and the RBT role fit together
A BCBA assesses a client, writes a behavior plan, and oversees progress. The RBT implements that plan session by session: teaching skills, collecting data, and reducing behaviors that get in the way of learning. The RBT exam is organized around six domains that map directly onto this role.
The six exam domains
- Data Collection and Graphing (17%): recording behavior accurately using methods like ABC data, momentary time sampling, and interval recording.
- Behavior Assessment (11%): supporting assessments like preference assessments and identifying functions of behavior.
- Behavior Acquisition (25%): teaching new skills through methods like discrete-trial teaching, chaining, and shaping.
- Behavior Reduction (19%): reducing interfering behaviors using reinforcement strategies and extinction.
- Documentation and Reporting (13%): writing session notes, completing incident reports, and communicating with your BCBA.
- Ethics (15%): following the RBT Ethics Code, staying within your scope of competence, and meeting supervision requirements.
Where to start
If you’re new to ABA, start with the RBT glossary to learn key terms, then work through each domain above. When you’re ready to test your knowledge, take a full practice exam or a topic-specific quiz.
