A BCBA is a board certified behavior analyst. A professional like this has a graduate degree in behavior analysis, education, or psychology. This professional also has been certified by the Behavior Analyst Certification Board. BCBAs specialize in applied behavior analysis (ABA) therapy. In their sessions, they use scientific techniques to influence how a person behaves in response to a trigger. For example, for children with autism,ABA might ease the urge to head bang in response to loud noises or strong emotions. BCBAs both design and administer ABA programs, and they may supervise technicians who carry out some of their plans.
