Work in CAS is not formally assessed, but recorded on a report. Diploma Option students spend the equivalent of approximately 3-4 hours per school week and a minimum of 150 hours over the course as a whole in creative, active and service-oriented endeavours with the time equally distributed between the three areas.
Students in Diploma, Diploma Programme Courses or Graduation options demonstrate that they have met the eight CAS learning objectives by April of their second year. It is important that students balance their commitment to CAS over the eighteen months of Grade 11 and 12.
CAS activities involve collaborative group work as well as individual effort, and the requirements for completion emphasise social interaction with others rather than passive involvement in activities. CAS experience may be gained either on or off campus. Northbridge offers a number of activities that are suitable for CAS, including Model United Nations, Student Council, sports teams, drama productions and service projects. Students are able, through these activities, to develop a greater awareness of themselves, a concern for others and the ability to work cooperatively with other people, as well as counterbalancing their academic commitments.
It is necessary that a teacher or another adult (a non-family member) acts as a supervisor who evaluates the student's performance in any CAS activity. A record must also be kept by the student documenting the amount of time devoted to CAS activities. Students work closely with the CAS Coordinator and their CAS Advisor who will help them to reflect on and record their experiences of CAS, as well as to plan and structure their time effectively. Students create a CAS exhibition at the end of Grade 11 which highlights their experiences thus far in the CAS programme.
Failure to meet the eight Learning Outcomes of CAS by the end of Grade 12, or to comply with the CAS requirements, will result in the award of the IB Diploma being withheld by the IB.
