Creativity, activity, service
Creativity, Activity, Service is a mandatory core component of the IB Diploma Programme. It aims to provide a "counterbalance" to the academic rigour of the educational programme. Before the 2010 examination there was a 150-hour requirement, with an approximately equal distribution of creativity, activity, and service. This requirement was removed mainly for two reasons: to ensure that students engage in meaningful activities and to decrease the amount of CAS fraud. Students are now expected to have two CAS activities for each CAS category and students need to prove that they are participating in CAS activities on a weekly basis. Moreover, students must have one CAS project which spans at least a month. Finally, one must prove that the CAS activities have resulted in the seven projected outcomes of CAS.
CAS aims
The function of CAS is to allow IB schools the opportunity to "give students the means to learn through experience how to take actions in the service of others."All the portions are vaguely defined and should, according to the International Baccalaureate Organisation, be interpreted as imaginatively as possible, so that a wide array of different activities can qualify for CAS. The learning outcomes and the quality of the CAS activity are of utmost importance.
