The terms ABA and BCBA are closely related but refer to different things. Applied Behavior Analysis (ABA) is a therapy approach that uses evidence-based techniques to help individuals with autism and other developmental challenges improve communication, social, and daily living skills. It focuses on understanding behavior and teaching positive alternatives through

A BCBA, or Board Certified Behavior Analyst, is the professional who designs, oversees, and monitors ABA therapy programs. BCBAs are highly trained specialists who assess each child’s needs, create personalized treatment plans, and guide a team of therapists to ensure consistent progress. In short, ABA is the therapy itself, while the BCBA is the expert who leads and supervises the process.


Both work together to help children with autism reach their fullest potential. The BCBA ensures that ABA therapy remains effective, ethical, and tailored to each child’s strengths and goals.

At Achieve Behavioral Therapy, our team of experienced BCBAs and dedicated therapists provide compassionate   ABA Therapy in New Jersey and North Carolina to help families   thrive.
