“Ratification” designates the international act whereby a State or regional economic integration organization affirms its consent to be bound by a treaty. The Convention is thus submitted to the ratification, acceptance, approval or accession of the Member States of UNESCO whose instruments have been deposited with the Organization’s Director-General (Article 26). It is also open to accession by non-Member States of UNESCO and regional economic integration organizations (Article 27).

Thus a Member State or regional economic integration organization wishing to become a party to the Convention must ratify it. The internal procedure leading to the deposit of the instrument of ratification with the Director-General of UNESCO varies considerably in terms of its duration and mode of implementation, as it is specific to each Member State or regional economic integration organization.

A model of the instrument of ratification (or acceptance, accession or approval, as appropriate) is set out below:
