The Inscriptic Movement contains all governmental and non-governmental organisations, groups and other persons who agree to be guided by the Inscriptic Charter. Its two primary constituents are:
- The UIC: the ultimate authority of the Movement
- The Institutional Inscriptic Committees (IICs): their mission is to develop, promote and protect the Inscriptic Movement in their institutions. The IICs are the only organisations that may apply to organise Inscriptic Days.
