The Senior High CCA framework has been designed to provide opportunities for students to discover their interests and pursue their passions, to develop new peaks of excellence at senior high and to maintain junior high peaks of excellence at senior high, and hence develop distinctive niches that characterize Dunman High School.  Hence, at the end of Year 4, students are encouraged to either propose new CCA that they wish to set up in their Senior High years, or to remain in their current CCA to further develop their areas of talent or to develop their leadership abilities, as leaders to their juniors. 

The Senior High CCA comprises school-based CCA and student-driven activities:

(1) School-based CCA are designated by the school as key CCA because they are either niche areas of excellence in junior high or new areas that appeal to youths.  In addition, Senior High students are also encouraged to play cameo roles beyond their core CCA.  This refers to them representing the school in competitions, as and when the need arises.

The CCAs include:

(2) Student-driven Activities
These activities are proposed by students based on their interests and passions. Students take ownership of these activities by planning activities, publicity and recruitment, as well as sourcing for necessary resources to implement their plan.
