The Student Committee is elected by Rosey students; it is responsible for organising numerous social and leisure activities and parties as well as promoting the integration of new students, ensuring, for example, that there is no bullying within the Rosey community. The committee also represents students who appear before a disciplinary council.
Multiple activities supplement the arts and sports offered at Le Rosey: cultural and literary clubs, debate clubs, the Model United Nations and the Yearbook preparation club. Rosey students participate in charitable activities managed in association with their Solidarity Committee, such as the academic group for Rosey Abantara in Mali (1500 young Malians are educated in a school which was built and partly conceived by Le Rosey), the Rosey Micro Finance Fund, and groups preparing humanitarian trips to Africa, Asia and Eastern Europe.
