Creativity, activity, service (CAS) is one of the three essential elements that every student must complete as part of the Diploma Programme.

The three strands of CAS, which are often interwoven with particular activities, are characterized as follows:

• Creativity – arts, and other experiences that involve creative thinking.
• Activity – physical exertion contributing to a healthy lifestyle, complementing academic work elsewhere in the DP.
• Service – an unpaid and voluntary exchange that has a learning benefit for the student. The rights, dignity and autonomy of all those involved are respected.

In order to demonstrate these concepts, students are required to undertake a CAS project. The project challenges students to:

• show initiative
• demonstrate perseverance
• develop skills such as collaboration, problem solving and decision making.
