The European Higher Education Area (EHEA) was formally established in 2010 and as of September 2016 has 50 members. Implementation of the various elements of the EHEA varies. Twenty-four countries have fully implemented a national qualifications framework and a further ten have a framework but have not yet certified it against the overarching framework; in 38 countries ECTS credits are used for all higher education programmes; 31 countries have fully implemented diploma supplements; and only 11 countries have included all the major points of the Lisbon Recognition Convention in national legislation.
