A Unique K12 School in Turkey:
Dual Curriculum • Global Education • Future Ready

Kilittaşı Schools, established in 2013 by Keystone International Schools, offers a distinctive K–12 dual curriculum education that combines the Turkish Ministry of National Education (MEB) program with the Ontario Secondary School Diploma (OSSD) from Ontario, Canada.

Through this internationally recognized model, students graduate with both a national diploma and the OSSD, opening doors to universities in Canada, the USA, Europe, and beyond.

Language Immersion from Early Years

Our Early Years Program (ages 24–72 months) is fully English-immersive. English remains the primary language of instruction in the early grades, with French introduced as a second language. In Grade 5, students experience a French-dominant year, followed by continued bilingual education in Turkish and English, with French maintained as an additional language. Annual educational trips to France support real-life language learning.

Internationally Accredited

Kilittaşı Schools has been accredited by WASC since 2018 and is a proud member of the Round Square global school network, offering students a truly international learning experience.
