ATCA is governed by a nine-member executive committee. Three ATCA members are elected to three-year terms each year. A member may serve no more than two terms consecutively, although they may run again after a year off from the committee. All members except associate and emeritus members may stand for election to the executive committee. The executive committee elects its own chair and vice-chair and appoints a secretary and treasurer. The secretary and treasurer need not be elected members of the executive committee. Notations of first or second term below refer to current term of service on the executive committee.
