Who We Are

The Component Council is comprised of one voting member from each ISA Chapter, Professional Affiliate and the Credentialing Council. It also includes non-voting members from each of ISA’s Associate Organizations and the TREE Fund.


The primary functions of the Council will be to provide a forum for collaboration and cooperation between ISA Component organizations; develop proposals to the Board of Directors concerning ISA policies, activities, and other matters of organizational interest; advise ISA on educational and similar programs of benefit to the membership and the Society; and develop and administer processes and activities that foster the free exchange of ideas and information among the Component organizations and the membership.
