Chapters

TYPE OF CHAPTERS

Metropolitan chapters may be established in an area where there is a nucleus of members. They may include students and graduates from accredited schools, in addition to qualified professional graduates in the geographical area.
Members-at-Large (those residing outside the area where an active chapter exists) are kept informed through the Coordinator of Members-at-Large. These members participate in the organization and elect their own delegates to the triennial convention.
