What Is Applied Behavior Analysis (ABA)?

Applied Behavior Analysis (ABA) is literally the science of behavior, examining the behavior of all living things. It employs evidence-based, scientific principles to build individually and socially beneficial behavioral repertoires, while reducing problematic ones (Cooper, Heron, & Heward, 2007).


What is the BACB® ?
