WELCOME TO KİLİTTAŞI SCHOOLS
A Unique K12 School in Turkey: Dual Curriculum Enriched Education!
Kilittaşı Schools was established in 2013 by Keystone International Schools. As of the 2025-2026 Academic Year, we will add high school education to our current preschool, primary and middle school education.
Education at Kilittaşı Schools is carried out with the Ministry of National Education curriculum for half a day and the Canadian education program implemented in our Keystone International Schools for the other half day. This model offers a very attractive educational opportunity for Turkish and naturalized foreign students who live abroad and have to return to Turkey. Our Keystone and Keystone students study on the same campus in a diverse and rich international cultural environment.
In pre-school education, between the 36 and 72 months, a completely English-oriented program is implemented and Turkish is not taught. In the preparatory class, students are taught to read and write in English. Until the 1st grade, English is the main language of instruction and French is offered as a second foreign language. From Grade 1 onwards, education continues with a half-day Ministry of National Education program and a half-day international Canadian program. French continues to be taught as a foreign language during this period.
In primary and secondary school, the biggest difference of Kilittaşı Schools is that the main languages of instruction are Turkish and English. Our students learn English with a mother tongue approach until the age of 6 and start primary school with an advanced knowledge of English. All of our branch lessons are taught in English. In 5th grade, our students have a basic knowledge of French and this year they progress with French-dominant language education. At the end of this process, students will be able to use French fluently in their daily lives. From the 6th grade onwards, Turkish and English continue as the main languages, with French as the second foreign language.
We believe that this unique model, which combines both the Ministry of National Education and the Canadian curriculum, sets us apart from other schools in Turkey. Our students not only receive education at international standards, but also grow up in a learning environment rich in cultural diversity. Keystone and Kilitaşı Schools have been accredited by WASC (Western Association of Schools and Colleges) since 2018 and are members of the Round Square school network, which includes elite schools around the world.
