The Student Representative Council is a group of students nominated by their peers. It is chaired by the College Vice Captains and meets regularly to discuss issues of concern and school decisions that affect them. As representatives of their Year group, the SRC representatives play an active role in assisting their Wellbeing Leaders in any special events and speaking on their Year’s behalf at assemblies.

Each of the Houses is led by two House Captains who have been elected from Year 11. They play an active role in their House assemblies, fostering House spirit and motivating participation in sporting events. They also organise lunchtime novelty events and speak at assemblies.
