Welcome to The Overseas School of Colombo (OSC)

I would like to take this opportunity to warmly welcome you to OSC! We are fully committed to guiding our community of learners toward international and intercultural understanding. As an IB World School, OSC develops the whole child as a responsible learner, striving for personal excellence within a culturally diverse environment.

Dually accredited, and IB authorized, OSC operates at the highest standards ensuring that its students are at the center of all decision-making. Starting from the IB Primary Years Program and moving into the Middle Years and High School IB Diploma Programs, OSC is steadfast in its vision to build independent, caring, and responsible world citizens who integrate perspectives, think critically, and are unwavering in contributing at both local and global levels to help shape a more sustainable world. OSC students are agents of their own learning who recognize that “together, embracing our differences, we can make a greater impact.”

Our students are welcoming and accepting. Eager and interested in learning, they follow their passions and personalize their education. Upon graduation, they matriculate to universities of their choice all over the world. The IB Diploma, widely acknowledged as the best preparation for post-secondary success, is highly recognized worldwide and provides the widest reach to all university systems across all nations.

OSC achieves its educational aims by attracting highly experienced, qualified, and enthusiastic teachers from all over the world. Our outstanding staff and faculty pride themselves in providing a positive and growth-minded learning environment which offers academic rigor paralleled by a diverse array of interesting and challenging programs including leadership opportunities, service activities, performing arts, and athletics. Together, as a community, we are all learners who are intellectually curious, engaged and involved in cultural heritage activities to realize our international-mindedness.

OSC families hail from more than 40 countries imparting our motto “unity in diversity.” We view parents as our partners and work in a genuine parent-school partnership which encourages all students to achieve our mission.

We all look forward to welcoming you to the OSC family.
