A Board Certified Behavior Analyst (BCBA) is a professional who specializes in applied behavior analysis (ABA), which is a scientific approach to understanding and changing behavior. BCBA is a credential awarded by the Behavior Analyst Certification Board (BACB), which is a nonprofit organization that establishes standards for the practice of behavior analysis.

BCBAs work with individuals of various ages and backgrounds, including children and adults with developmental disabilities, behavioral disorders, or other challenges. They use evidence-based strategies to assess behavior, design and implement interventions, and measure the effectiveness of those interventions over time. The ultimate goal of a BCBA is to help individuals improve their quality of life by teaching new skills, reducing problematic behaviors, and promoting positive behaviors.

To become a BCBA, individuals typically need to meet specific educational requirements, complete supervised experience hours in the field of behavior analysis, and pass a comprehensive exam administered by the BACB. BCBAs are expected to adhere to a professional code of ethics and engage in ongoing professional development to maintain their certification.
