The three-member Board of Trustees is the supreme organ of the Worlddidac Foundation for the period of four years. They operate under external and independent authority. The election to the Board of Trustees are made by co-optation, whereby the Board of Trustees generally consists exclusively of members of the Board of Directors and/or employees of the Worlddidac Association office. The Board of Trustees constitutes itself. In particular, it designates its President, its Vice-President and the Treasurer of the Foundation.
