Executive Council

The CSCA Executive Council (EC) consists entirely of unpaid volunteers. Under normal circumstances, the Council structure proceeds as follows: Every three years, the EC brings on a new vice president from among our membership. At that time, the existing vice president becomes president, the existing president becomes past president, and the existing past president retires from the EC. The positions of Secretary, Treasurer, and Student & Early Career Rep. are not limited to specific terms. The Executive Director serves at the pleasure of the EC, with a review every five years.
