The committee consists of 14 members (including a chair), plus two trainees. The chairs of the AGA Institute Practice Management and Economics Committee and the AGA Institute Quality Committee (who shall not count against the maximum membership) shall be ex-officio members of the committee. A councilor (who shall not count against the maximum membership) shall serve as the governing board’s liaison to the committee and shall attend all committee meetings; additional members of the governing board (who shall not count against the maximum membership) may be assigned as team members to the committee but are not intended to attend any committee meetings.
