On 11 April 1997, in Lisbon, the Council of Europe and UNESCO open for signature the Convention on the Recognition of Qualifications concerning Higher Education in the European Region — the Lisbon Recognition Convention.

The text gradually replaces networks of bilateral and multilateral diploma-equivalence treaties. Its core principle: a qualification or period of study must be recognised unless the competent authority proves substantial differences.

Depositaries are the Secretary General of the Council of Europe and the Director-General of UNESCO; the authentic languages are English and French. Entry into force: 1 February 1999.

The Convention establishes a monitoring Committee and the ENIC Network (national information centres on academic mobility). It is the only legal treaty of the European Higher Education Area (Bologna Process).

By 2026, 57 states are parties — all Council of Europe members, plus Australia, Canada, the Holy See, Israel, Kazakhstan, Kyrgyzstan, New Zealand, Tajikistan, Turkmenistan and Belarus. The United States has signed but not ratified.

Subsidiary recommendations cover assessment of foreign qualifications, recognition for refugees, and the use of national qualifications frameworks.

The Lisbon Recognition Convention of 11 April 1997 remains the legal basis for fair diploma recognition in Europe and partner UNESCO states.
