Kilittaşı & Keystone is the only school in Turkey that is a member of the Round Square Organization. Round Square is an international organization for educational purposes. It focuses on six main topics in terms of personal development and responsibility: Internationalism, Democracy, Environment, Adventure, Leadership, and Service. These concepts contribute to the holistic development of students. Our children between the ages of 3 and 18 grow up with an educational curriculum that includes these core values. Round Square activities and projects contribute to the holistic growth and development of students within the Round Square network, which consists of member schools from the most developed countries in the world.

Being part of the Round Square Organization offers various opportunities such as teacher and student exchange programs, sharing best practices, access to resource libraries, and active participation in service projects.

Round Square is a school association consisting of 200 schools in 50 countries worldwide and enables member schools to collaborate while developing these core understandings in students. Round Square and its ideals have been integrated into the Kilittaşı Schools curriculum.
