The Overseas School of Colombo (OSC) is a non-profit educational institution providing a world class education to foreign and local students in Sri Lanka. Established in 1957, OSC remains Sri Lanka’s premier and only internationally accredited educational institution, providing the International Baccalaureate programme from pre-school to grade 12. OSC is a fully modernised and air-conditioned campus set on a purpose-built, green and spacious campus designed to create a natural setting for students living in a busy city.
At OSC, we represent students from over 40 different nationalities and well qualified teachers from 10 different countries.
In a multicultural environment such as ours we instill values of respect and tolerance in our students.
We provide a scholastic atmosphere that enables students of different nationalities to excel academically while discovering their own gifts and talents and help them grow into socially and culturally conscious adults. OSC is Sri Lanka’s Truly International School!
