Compulsory education in Greece comprises primary schools (Δημοτικό Σχολείο, Dimotikó Scholeio) and gymnasium (Γυμνάσιο). Nursery schools (Παιδικός σταθμός, Paidikós Stathmós) are popular but not compulsory. Kindergartens (Νηπιαγωγείο, Nipiagogeío) are now compulsory for any child above 4 years of age. Children start primary school aged 6 and remain there for six years. Attendance at gymnasia starts at age 12 and last for three years.
Greece's post-compulsory secondary education consists of two school types: unified upper secondary schools (Γενικό Λύκειο, Genikό Lykeiό) and technical–vocational educational schools (Τεχνικά και Επαγγελματικά Εκπαιδευτήρια, "TEE"). Post-compulsory secondary education also includes vocational training institutes (Ινστιτούτα Επαγγελματικής Κατάρτισης, "IEK") which provide a formal but unclassified level of education. As they can accept both Gymnasio (lower secondary school) and Lykeio (upper secondary school) graduates, these institutes are not classified as offering a particular level of education.
Public higher education is divided into universities, "Highest Educational Institutions" (Ανώτατα Εκπαιδευτικά Ιδρύματα, Anótata Ekpaideytiká Idrýmata, "ΑΕΙ") and "Highest Technological Educational Institutions" (Ανώτατα Τεχνολογικά Εκπαιδευτικά Ιδρύματα,Anótata Technologiká Ekpaideytiká Idrýmata, "ATEI"). Students are admitted to these Institutes according to their performance at national level examinations taking place after completion of the third grade of Lykeio. Additionally, students over twenty-two years old may be admitted to the Hellenic Open University through a form of lottery. The Capodistrian University of Athens is the oldest university in the eastern Mediterranean.
