Each year St Philip's sends teams of representatives to regional and international conferences held at a member school.
During the international conference the prior year's collaborative activities are reported on and evaluated, and new projects are planned. Discussions, related to the theme of the conference, examine topics of importance to the member schools and the world.
Programmes initiated by Round Square help institutionally and culturally different, but like-minded students meet and share their points of view. Friendships are made through activities, expeditions and events organized by the host school. Visitors are introduced, not only to the host school, but also the country, the culture and the environment.
