All students in the Senior School are challenged to get involved in the wider community. The “CAS” program is a requirement of the IB diploma program and is completed by students in grades 11 and 12. The emphasis is on learning by doing tasks that have real consequences and then reflecting on these experiences over time.
In their final two years of high school, each HGS student completes a minimum of 150 hours of unpaid and extra-curricular work in the three areas of the CAS program: creativity, action and service. The student experience at HGS, regardless of grade level, informally involves all three elements of the program.
