Welcome to The Overseas School of Colombo
The Overseas School of Colombo (OSC) is widely regarded as the most prestigious international school in Colombo, Sri Lanka.
OSC is committed to guiding our global community toward international and intercultural understanding while focusing on the development of the whole person as a responsible learner, striving for personal excellence within a culturally diverse environment.
As an International Baccalaureate World School offering all three programme levels of PYP, MYP and IBDP, we proudly serve students from 40 nationalities, from Preschool to Grade 12.Â Our vision is for OSC to be a model of excellence in education; nurturing and empowering our community of learners to achieve global success.
Located on a green and spacious campus in Battaramulla, a suburb of Colombo, OSC is dedicated to developing our students into responsible learners, striving for excellence within a culturally diverse school. While academic expectations are high, our students are also encouraged to participate in a broad range of cultural, athletic and community service endeavors.
At OSC, we are a welcoming community school, where parents and teachers are partners in the education of our students. Working together, we create the kind of environment where children not only learn, but thrive.
We welcome students from around the world and we hope that you will learn more about us on our website. Do not hesitate to contact us if you require further information.
Head of School
Students must be at least three years of age on or before 31 August of the academic year of entrance for admission to the Pre-School.
Admission is granted to a student when it has been determined that the school has a vacancy and an appropriate programme to meet his/her individual needs. The final determination of grade placement will be made by the Head of School.
This placement will reflect the studentâ€™s previous educational experience, age, maturity, linguistic proficiency and academic needs. In certain circumstances students will be placed in a lower grade level to meet their educational needs.
In the Preschool, the school aims for a target of 15 students with a teacher and assistant teacher in each class. This number may increase to 20 at the discretion of the Head of School after consultation with the Primary Principal.
From Kindergarten through to Grade 12, the school aims for a target of 20 students. This number may increase to 24 at the discretion of the Head of School in consultation with the relevant Principal.
English is the teaching medium in the school and there is an expectation that students have, or will acquire, a satisfactory standard of English. The school maintains an EAL support programme. However, it should be stressed that non-English speaking students should gain maximum exposure to the language and if a student does not have a satisfactory standard of English at the time of application, the Head of School may refuse admission if there is no appropriate programme to cater for the studentâ€™s needs.
OSC does not undertake to provide for all specialized educational needs such as severe learning difficulties or job-specific vocational training. Mild to moderate special educational needs may be provided for from Pre-School to Grade 8 depending on the level of service required. In the Secondary School (Grades 9-12), the courses are essentially college-preparatory and with a demanding academic emphasis. Support for students with learning disabilities at this level is very limited.
