The Overseas School of Colombo (OSC) is widely regarded as the most prestigious international school in Colombo, Sri Lanka.

OSC is committed to guiding our global community toward international and intercultural understanding while focusing on the development of the whole person as a responsible learner, striving for personal excellence within a culturally diverse environment.

As an International Baccalaureate World School offering all three programme levels of PYP, MYP and IBDP, we proudly serve students from 40 nationalities, from Preschool to Grade 12.  Our vision is for OSC to be a model of excellence in education; nurturing and empowering our community of learners to achieve global success.

Located on a green and spacious campus in Battaramulla, a suburb of Colombo, OSC is dedicated to developing our students into responsible learners, striving for excellence within a culturally diverse school. While academic expectations are high, our students are also encouraged to participate in a broad range of cultural, athletic and community service endeavours.

At OSC, we are a welcoming community school, where parents and teachers are partners in the education of our students. Working together, we create the kind of environment where children not only learn, but thrive.

We welcome students from around the world and we hope that you will learn more about us on our website. Do not hesitate to contact us if you require further information.
