Applied Behavior Analysis (ABA) is the leading evidence-based treatment approach for autism and other developmental disabilities.


What is it?

ABA practice focuses on assessing the environmental influences on behavior, assessment-based intervention, and data-based decision making.

More than four decades of research has found ABA to be the most effective treatment for children and adolescents with autism and other developmental disabilities, producing meaningful and significant changes in language, cognition, play, social, daily living skills, and challenging behaviors.

Behavior analyst certification board

The Behavior Analyst Certification Board®, Inc. (BACB®) is a nonprofit 501(c)(3) corporation established in 1998 to meet professional credentialing needs identified by behavior analysts, governments, and consumers of behavior analysis services.

All BACB requirements and exam content are established by content experts in the discipline.

Reimbursement & Licensure

Behavior analysts have been practicing independently, without oversight from other professions, for decades. Funding streams include Medicaid waivers and health-insurance plans, among others. BACB certificants are identified as qualified providers of ABA services in the majority of the recently passed autism health-insurance laws. BACB standards are the basis of the vast majority of existing behavior analyst licensure/certification laws in the United States.
