CAS is one of the three core courses of the IB diploma programme. A successful completion of CAS is one of the requirements for obtaining the IB diploma.


This can cover a wide range of arts and other activities outside the normal curriculum. Examples of such activities can be doing dance, theatre, music and art. It may also include creative thinking in the design and carrying out of projects.


For CAS, action refers to physical action. It can include participation in individual and team sports, and physical activities outside of the normal curriculum. It may also include physical activity involved in carrying out creative and service projects.


Service involves interaction, such as the building of links with individuals or groups in the community. The community can be the school, the local district, or it may be at the national or international level.

The relationship should show respect for the dignity and self-respect of others. There should be prior communication and full consultation with the community or individual concerned. The service provided should be appropriate and you should be able to understand the consequences of what you are doing.
