The school is also a Global Member in the Europe and Mediterranean region of the Round Square Organisation. This is a prestigious network of 180 schools in 50 countries, all of which take a holistic approach to education, based on six ‘Ideals of Learning’ – Internationalism, Democracy, Environmentalism, Adventure, Leadership, Service – first put forward by the German educational philosopher Kurt Hahn in the 1960s. Membership of the Round Square network offers St Mary’s a framework for excellence and continuous improvement, as well as opportunities to collaborate and share experiences with like-minded peers around the world.
