Step into a realm where educational excellence has been the hallmark since 1957. The Overseas School of Colombo (OSC), Sri Lanka’s oldest international school, invites you to embark on a journey of unparalleled academic finesse, cultural richness, and global opportunities.

Excellence in Education: The IB Advantage

As the only IB World School in Sri Lanka, OSC sets the gold standard for academic excellence. The globally recognised International Baccalaureate (IB) curriculum empowers students to become critical thinkers, compassionate leaders, and lifelong learners. Unlike traditional rote learning, the IB philosophy fosters inquiry-based learning, equipping students with the skills and mindset needed to thrive in an ever-evolving world.

Leading the Way in Educational Innovation

In a rapidly changing world, OSC remains at the forefront of educational innovation. Our commitment to experiential learning ensures that students are not just passive recipients of knowledge but active participants in their own education. Through hands-on projects, service-learning initiatives, and interdisciplinary experiences, OSC prepares students to tackle real-world challenges with creativity, empathy, and resilience.

Beyond Borders: A Global Outlook

At OSC, students transcend geographical boundaries, engaging in a truly global educational experience. With over 40 nationalities represented among our student body and faculty from 16 different countries, OSC cultivates a diverse and inclusive community where students learn from each other’s perspectives. From international sporting tournaments to prestigious competitions like the FIRST LEGO League, OSC provides students with opportunities to shine on the world stage, fostering resilience, adaptability, and a global mindset.

Truly International, Deeply Rooted in Sri Lankan Heritage

While OSC proudly stands as a beacon of international education, our Sri Lankan roots run deep. Embracing the vibrant tapestry of Sri Lankan culture, OSC ensures that students maintain a strong connection to their heritage through initiatives like the Mother Tongue programme, service-learning, the annual ‘Week Without Walls: Experience Sri Lanka!’ programme and vibrant celebrations of local festivals. From Sinhala and Tamil New Year to Vesak and Eid, our campus pulsates with the rhythms of Sri Lankan traditions, ensuring that every student feels at home while embracing global perspectives.

Investing in Excellence: Your Child’s Future Starts Here

At OSC, we believe that every child deserves access to a world-class education. With a teacher-to-student ratio of 1:5, OSC ensures that each student receives personalised attention and support to thrive academically and personally. Our commitment to excellence extends beyond the classroom. OSC is dedicated to safeguarding the welfare of all children and young people, and we expect all staff, parents, and volunteers to share this commitment. Additionally, OSC proudly holds the distinction of being Sri Lanka’s first Eco-School, further demonstrating our dedication to holistic education and environmental stewardship.
