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 programmes such as Drama productions, Music ensembles, and other leadership opportunities such as Model United Nations.

Every year, OSC hosts the Colombo Model United Nations (COMUN) with schools from within Sri Lanka and Internationally as well.

OSC participates in competitions with international schools in the region belonging to South Asia Inter-School Association (SAISA). We regularly prepare teams for Swimming, Basketball, Volleyball, Soccer/Football and Athletics. (Due to the current worldwide COVID situation, the SAISA tournaments have been placed on hold.)

The purpose of SAISA is to promote and co-ordinate regional professional activities, fine arts festivals, athletic tournaments and other events. We also offer a variety of informal sport activities like cricket, badminton and ultimate frisbee.
