Affiliated chapters are organizations associated with the Association of Behavior Analysis International, whose mission involves the dissemination and growth of behavior analysis. Recently, there has been an increase in the number of chapters that have been established in the United Statesover a third of all U.S. ABA Affiliate Chapters were established within the past 4 years. The purpose of this panel discussion is to review the history of several successful ABA affiliate chapters, and review how each organization is structured, what the goals are, and what the chapters have done to increase membership in their organizations. In addition, panelists will review how they have organized and improved the quality of their respective conferences. Individuals from several affiliate chapters will participate, including the Berkshire Association for Behavior Analysis and Therapy (BABAT), the Maryland Association for Behavior Analysis (MABA), the California Association for Behavior Analysis (CalABA), and the Connecticut Association for Behavior Analysis (CTABA).
