23 September 1957, marks the day that the Colombo School for Overseas Children was founded. Meant for children aged between 5 and 12 years whose residence on the island was temporary, the School was to assist these students to make the transition to and from the education systems of their own countries. Located at Queen’s Street in Colombo Fort, the founders of this new school were from diplomatic missions and the business community, which still reflects the School population today.
As the School grew, the premises known as “Rippleworth” at Turret Road (Dharmapala Mawatha) in Colombo 03 was leased, splitting up the younger children and the older students into the two buildings. Soon, however, another change was needed, and in 1971 the School was moved to the wholly new location of 51 Muttiah Road in Colombo 02 (Rivington) until finally in 1983 the School was relocated to its present address: Pelawatte, Battaramulla. At the time, the new location was barren land, however the campus blossomed as both the school buildings and the surrounding wildlife grew in tandem into the wonderful place we occupy today. While the School has always offered After-school activities such as volleyball, football, and swimming, the site itself has evolved into a magnificent centre of activity, with a gymnasium, swimming pool, sports field, and performance arts facility sitting alongside state-of-the-art labs, and well-maintained libraries showcasing the School’s commitment to developing multi-faceted individuals keen on expanding their minds with a natural curiosity that beckons them to explore the world around them.
The School took its present name, The Overseas School of Colombo, in 1996 and to date, remains Sri Lanka’s oldest internationally accredited educational institution. Steeped in such rich history, we are proud of OSC’s role as a home for internationally mobile expatriate children as well as Sri Lankan students. As a culturally diverse community, we look back on our journey and the challenges we’ve overcome together and face the future with fearless courage, knowing that adhering to the tenet of “unity in diversity” is the only way we can keep on advancing a legacy of excellence.
