Applied Behavior Analysis (ABA) is a scientific approach to understanding behavior. ABA refers to a set of principles that focus on how behaviors change, or are affected by the environment, as well as how learning takes place. The ultimate goal of ABA is to establish and enhance socially important behaviors.

ABA can be used for anyone at any age to learn or change most any kind of behavior. The application has been successful across populations from children to adults with various developmental, learning, and mental health needs.
