Composed of sixteen members elected for a period of three years [the president, two vice-presidents, the treasurer and eleven ordinary members and the chairperson of the Advisory Committee (who is an ex-officio member)], the Executive Council is the governing body of ICOM and generally meets twice a year. It ensures that the decisions and resolutions of the General Assembly are given effect and that ICOM's Strategic Plan is carried out. It takes action to implement the proposals and recommendations of the Advisory Committee and, if necessary, co-ordinates the work of National Committees, International Committees and Regional Organisations. ICOM members may participate as observers in the meetings of the Executive Council.
