WHERE GLOBAL EDUCATION BEGINS

Kindergarten | Primary School | Middle School Anatolian High School

A Global University Pathway Without Exam Limitations

MEB + Canada Dual Diploma

Founded in 2013 by Keystone International Schools, Kilittaşı Schools offers a distinctive K–12 dual curriculum model that brings together the Turkish Ministry of National Education (MEB) program and the Ontario Secondary School Diploma (OSSD) from the Province of Ontario, Canada.

Through this integrated academic structure, our students graduate not only with a national high school diploma but also with a second internationally recognized diploma. As a result, their university choices are not limited to Turkey; they gain direct and advantageous access to universities in Canada, the United States, Europe, and around the world.

Dual Diploma = Double Assurance

Upon graduation, Kilittaşı students receive:

  • Turkish Ministry of National Education (MEB) High School Diploma
  • Ontario Secondary School Diploma (OSSD)

This model expands students’ opportunities.

Their future is not dependent on a single examination.

Final university decisions can be made at the end of high school — not at the beginning.

Strong Language Proficiency from an Early Age

Our Early Years Program (24–72 months) is built on natural English acquisition. In the early grades, the language of instruction is English, while French is introduced as a second language.

In Grade 5, students experience an intensive year of French. Thereafter, bilingual Turkish–English education continues, while French develops as a strong third language. Traditional educational trips to France extend language learning beyond the classroom into real-life experience.

Academic Depth and Global Standards

Critical thinking, research culture, and problem-solving skills are at the core of our curriculum.

Students are fully prepared — academically and linguistically — for university-level expectations.

Kilittaşı Schools:

  • Is accredited by the Western Association of Schools and Colleges (WASC)
  • Is a proud member of the Round Square global school network

This strong foundation provides our students with a truly international learning ecosystem.

The Future Is Not a Coincidence — It Is a Designed Journey

At Kilittaşı, education goes beyond academic success. It cultivates global confidence, cultural awareness, and strategic future planning.

Because we see education not merely as a process, but as the design of a future.

STUDENT AND PARENT TESTIMONIALS

As parents and foreigners we are thrilled to have found Keystone International Schools for our kid’s education here in Istanbul. We are a family from South America, Argentina, Ecuador and Brazil, and we have been living abroad since Luca was just 5 months, so it is important to find a school that will give us the confidence that he is developing his intellectual and social skills in a healthy and friendly environment. This has been the case with Keystone. Since day one the teachers and staff have been amazing, very warm, communicative and experienced. Luca is returning everyday happy from school and we are just filled with joy. Thanks Keystone for making this experience unforgettable.

Sebastian, Karina & Luca Balladares

Keystone is a very unique school with audacious vision of its founders to provide a holistic learning experience to students from all over the world. … Our daughter in her 14 years wrote a novel, published it in Amazon, traveled to the US with public speaking at Harvard, was recipient of scholarship from Johns Hopkins University Center of Talented Youth. These all happened because she grew up in environment entrusted in her skills and nourishing her personality with unique experiences. She is a regular kid growing in a great school. And this is just a beginning of her life. Wishing all kids grew in such an environment with respect to personality and thoroughly guidance by building up a confidence in themselves.
