Located in the heart of Sri Lanka, The Overseas School of Colombo (OSC) is a vibrant community where education inspires growth, curiosity, and meaningful connections. Established in 1957, OSC is the oldest internationally accredited school in Sri Lanka and remains the only IB World School in the country. Recognised by the Council of International Schools (CIS) and the Middle States Association of Colleges and Schools (MSA), OSC offers a world-class education tailored to meet the unique needs of every student.

Diversity is at the heart of OSC's identity. With students from over 40 nationalities, the school fosters an inclusive environment, embracing Unity in Diversity. This creates a dynamic setting where intercultural understanding, empathy, and collaboration flourish-qualities that prepare students for success in both the classroom and a global society.

At OSC, learning is personalised. With a teacher-to-student ratio of 1:6, each child benefits from individual attention and support to thrive. Our dedicated faculty, drawn from across the globe, inspire curiosity, creativity, and resilience, helping students grow into compassionate, confident global citizens. Offering the full IB continuum, OSC blends academic rigour with a holistic approach to education. Beyond academics, students excel in the arts, athletics, and personal development, gaining skills that will equip them for the future.

The safety and well-being of every student is a top priority. With a Designated Safeguarding Lead, a Child Protection Officer, three counsellors, and an educational psychologist, OSC ensures that students are fully supported in a secure and nurturing environment. Safeguarding policies underpin our commitment to protecting the physical and emotional health of each child.

OSC's purpose-built campus inspires exploration and creativity. Students benefit from cutting-edge laboratories, dedicated spaces for art, music, and drama, and extensive sports facilities, including a 25-metre swimming pool, a gymnasium with a rock-climbing wall, and expansive courts and fields. These spaces enable students to engage in a variety of activities that complement their academic growth.

A leader in sustainability, OSC is recognised globally with the MSA Programme of Distinction in Sustainability and the Eco-Schools Green Flag Award. These accolades highlight OSC's commitment to environmental education and sustainable practices.

At OSC, every child is seen, supported, and celebrated. Families who join us discover a warm and inclusive community, where academic excellence, personal growth, and a sense of belonging come together. Students leave OSC confident, compassionate, and ready to shape a brighter future-for themselves and the world.
