The main structures for quality assurance procedures are the Hellenic Authority for Higher Education (HAHE) at the national level and the Quality Assurance Unit (MODIP) and the Internal Evaluation Teams of Academic Departments (OMEA) at the university level.

HAHE (https://www.ethaae.gr/el/) is an independent institutional body with administrative autonomy, which is supervised by the Minister of Education and Religious Affairs to control the legality of its actions. Its mission is to support universities in carrying out procedures aimed at ensuring and improving the quality of their work, ensuring the transparency of the procedures they follow, promoting research on relevant issues and informing the State and institutions about contemporary international developments and trends in this field.
