CAS Creativity Action Service

The CAS activities stressed on the importance of life outside the school. The activities encourage students to share their energy and talents with others : students may, for example, take part in theatrical and musical productions, in sports or community service projects. Creativity is interpreted broadly to include a wide range of artistic activities in addition to those that students perform during the design and implementation of service projects. This may include not only participation in individual sports and team, but also participation in local and international projects. The service includes hosting activities and services for the community and society. More information on the site of the IB : http://www.ibo.org/fr/pyp/
