GWHA was created to ensure Good Will's most substantial supporters feel part of its operations. Its primary responsibility is to elect the Board of Directors and GWHA membership.

These activities happen during the annual meeting, usually held the first Saturday of August. The meeting takes place on the Good Will-Hinckley campus. GWHA members must be present to participate.

As of August 2, 2008 GWHA membership was 266-strong. Membership in the GWHA is for life. Any member may voluntarily resign his or her membership.

Membership Criteria:

Any person who qualifies under the following categories and is subsequently elected at a meeting of the GWHA:

a) All who are members on the date of the revisions of the by-laws (August 2, 2003).

b) Any person known to have contributed an aggregate of $2,500 to the GWHA.

c) Any student who graduated from the GWHA's high schools; completed a prescribed course of study; or has been a student in the GWHA's schools for four years and has contributed an aggregate of $1,000 to the GWHA.
