OSC’s Experiential Education program fulfils key goals of our mission and vision by providing students learning opportunities beyond the context of the classroom. Students are challenged physically, socially, emotionally and intellectually. They face new challenges, broaden their experiences, engage with issues of global importance and develop a greater self-awareness. To fulfil these goals, OSC offers a range of activities that include the arts, sports and service. Students are encouraged to participate in these programmes as these activities give balance to a student’s life.

Creative Activities include puppet making; comic book making; lego club; origami; construction club; sewing; drama; ukulele, and art club.

Sports activities include basketball; Gecko swim club; team games; football; track and field; Zumba, and karate.

Our service activity is the Primary School Government Ambassadors.

OSC primary children participate in competitions against other international schools in Colombo, in Football, Swimming, and Track and Field Athletics. We also belong to South Asia Inter-School Association (SAISA). We regularly prepare secondary school teams for Swimming, Basketball, Volleyball, Soccer/Football, and Track and Field Athletics. Athletes from grade 5 are eligible to participate in the Swimming and Track and Field Athletics competitions.  (Due to the current worldwide COVID situation, the SAISA tournaments have been placed on hold.
