Why Keystone?

Why Kilittaşı?

At Kilittaşı Schools, we believe education should prepare students not only for exams, but for life in a global world. Our unique approach combines academic excellence, multilingual education, and internationally recognized qualifications, all within a nurturing and culturally rich learning environment.

Dual Diploma Advantage

Students graduate with both the Turkish national diploma and the Ontario Secondary School Diploma (OSSD), a globally recognized qualification that opens doors to top universities in Canada, the USA, Europe, and beyond.

International Standards, Local Roots

By combining the Turkish Ministry of National Education curriculum with the Canadian Ontario education system, Kilittaşı offers the best of both worlds—strong national foundations alongside international academic standards.

Language Immersion from an Early Age

From the early years, students benefit from a full English-immersion program, acquiring the language naturally through a mother-tongue approach. French is introduced early and strengthened through a French-dominant year in Grade 5, supported by real-life immersion experiences in France.

Future-Ready Education

Our curriculum develops critical thinking, problem-solving, research skills, and academic writing, ensuring students are fully prepared for university and future careers worldwide.

Globally Accredited & Connected

Kilittaşı Schools has been WASC-accredited since 2018 and is a proud member of the Round Square network, connecting our students with leading schools and global learning opportunities around the world.

A Global Community

Our diverse school community helps students grow with cultural awareness, confidence, and adaptability, preparing them to thrive in an increasingly interconnected world.
