The organization of a major international exhibition requires a considerable amount of work that usually covers a period of four or five years. Exhibitions in national museums are scheduled several years in advance by a special committee which meets regularly at the RMN's head office.

The RMN also administers loan applications as well as the shipping and insurance of works of art. Together with the exhibition commissioners, the RMN chooses the architect-designer who will be in charge of mounting the exhibition.
