We educate international students from ages 3 to 18. We are the only Early Years through Grade 12 international school in Istanbul to be fully authorized by the International Baccalaureate Organization for all 3 IB programs and globally accredited by ECIS and NEASC. Founded in 1911, we are one of the oldest international schools in the world. We have 2 campuses, one in Rumeli Hisari for ages 3-9 and a purpose built campus in Hadimkoy for ages 3 to 18.
