In the field of applied behavior analysis (ABA), you will often see the qualifications “RBT” and “BCBA.” While both play important roles in behaviour-analytic services, they differ significantly in terms of education, responsibilities, autonomy, and career trajectory. For those preparing to enter the field or advance their credentials, using an RBT mock exam can be an excellent way to test your knowledge, identify areas for improvement, and build confidence before certification. Understanding these differences is essential if you’re considering entering the field, either as a direct service provider or a supervisor/analyst.

Defining the Roles

What is an RBT?

A Registered Behavior Technician is a credentialed paraprofessional who works under the supervision of a BCBA (or, in some cases, a higher-level behaviour analyst). Their primary function is to provide direct, hands-on services to clients: implementing behaviour intervention plans, collecting data, assisting with skill acquisition and behaviour reduction strategies.

What is a BCBA?

A Board Certified Behavior Analyst is a practitioner who has completed graduate-level education, supervised experience, and a certification examination. BCBAs are qualified to conduct assessments, design behaviour intervention plans, supervise RBTs, track outcomes, and make clinical decisions. (more…)
