Costeas-Geitonas School (CGS) is one of the largest educational organizations in Greece and our vision and commitment to our principles has continued to inspire us for the past forty years.

Established in 1973 and governed by a Board of Directors, CGS is one of Greece’s oldest and most prestigious private schools, providing educational programmes from the pre-school to the secondary school level. Located in Pallini, a northern suburb of Athens on a 67,000 m2 campus, CGS has a student population of 1,910. The majority of the student body is comprised of Greek nationals but there is an emerging international and bi-cultural student population. There are 231 teaching faculty across all levels and 278 members of the school administration.

The school’s vision and mission statement along with the educational philosophy of the IB programmes implemented in all school divisions (IB Continuum), offer a competitive advantage to its students who are able to combine their studies in a Greek school with exceptionally high international academic standards.
