Founded in 1957, The Overseas School of Colombo is Sri Lanka’s oldest internationally accredited educational institution. It is the only school in Sri Lanka to offer the International Baccalaureate Programme from Pre-school to Grade 12. OSC is a multi-national English medium international school catering to the needs of the internationally mobile expatriate community and Sri Lankan students. At OSC we provide the scholastic atmosphere that enables students of all nationalities to excel academically while helping them grow into socially and culturally conscious adults in an environment of respect and tolerance.

The school campus is located in Battaramulla, a suburb of Colombo, with a scenic drive past Sri Lanka’s Parliament complex designed by an internationally renowned local architect Geoffrey Bawa. The newest Golf and Leisure Complex in the country, Water’s Edge, is a 5 minute drive from the school. Water’s Edge boasts an 18 hole golf course, restaurants, bars, a gymnasium, swimming pool, spa and karaoke lounge. The school campus stretches over five acres of land and encompasses within its substantial grounds all the educational and sports facilities that will make your child’s time here a stimulating and enjoyable experience.

OSC is the only complete IB World School in Sri Lanka. We offer three IB Programmes that run from Pre-school to Grade 12. Based on the requirements of the British, American and Australian education systems, the IB Programmes focus on developing the child as a whole by providing the opportunities for each individual to realise his/her potential to the fullest.
