ACHA is divided into 11 affiliates arrayed across six regions of the United States.
Each affiliate conducts its own or combined annual educational meeting to give college health professionals the opportunity to network specifically with others in the same region or to learn more about regionally specific issues.
Members of ACHA receive free automatic membership in one of the affiliate organizations based upon geographic location. International members are likewise apportioned to membership in one of the affiliates according to their international location as set forth in procedures established by the association's Board of Directors.
Each of these affiliates is governed by its own elected officers who provide guidance and leadership to members.
