The Board Certified Behavior Analyst® (BCBA®) is a graduate-level certification in behavior analysis. Professionals certified at the BCBA level are independent practitioners who provide behavior analysis services. Individuals who hold a BCBA certification are able to provide behavior analysis services to clients without supervision from another therapist. If a BCBA provides ABA therapy to their clients, they focus on the function of behavior and how behaviors are affected by the environment. This approach to behavior analysis is widely used in children with autism, because there is empirical evidence to support its success. BCBAs can work in a variety of settings with individuals of all ages. You might find BCBAs working in a school setting, private practice, or a therapeutic preschool program.
