Higher education in Greece consists of two sectors: the University Sector, which includes Universities and the Technological Sector, which includes Higher Technological Education Institutions (TEI). Currently there are 24 Universities and 16 TEIs, all of which are considered accredited by Greek state. All the Higher Tertiary state-accredited universities and TEIs in Greece are public. The duration of the undergraduate degree programs for most disciplines is 4 years but there are programs in engineering, dentistry, pharmacology, agronomics, forestry, and fine arts, with a duration of 5 years and medicine with a duration of 6 years. These credits are accumulative and transferable under the European Credit Transfer and Accumulation System (ECTS).
Apart from the higher education institutes, a number of private institutions, known as Colleges, operate in Greece as well. However, the current Constitution of Greece prohibits private institutions for post-secondary education, from operating as independent universities. Colleges overcome this constraint by establishing collaboration with foreign universities to offer undergraduate and postgraduate programmes. According to the current legislation, as derived by the incorporation of EC Directive 2005/36, holders of academic degrees by universities in the European Union, including those obtained through studies at a college in Greece, have their professional rights fully recognized.
