The ESG are the Standards and Guidelines for Quality Assurance in the European Higher Education Area (EHEA). As part of the Bologna Process, European ministers responsible for higher education adopted the ESG as a common framework for quality assurance.
EQAR (European Quality Assurance Register for Higher Education) is the official register of quality assurance agencies operating in substantial compliance with the ESG.
DEQAR is the Database of External Quality Assurance Results produced by EQAR-registered quality assurance agencies.
