Greece's education system has undergone changes over the years, with the last major change occurring in 2000 when senior high schools split into lyceums and technical vocational schools. The Greek education system includes nursery school starting around age 3, primary school from ages 6-12, and gymnasium (junior high school) as the last mandatory level. After completing 9 years of basic education, students can choose to stop or continue their education at lyceums, technical vocational schools, or vocational schools, which have different structures and focuses to prepare students for university or careers. Graduating students must pass school exams to attend public university faculties in Greece.
