Through its Royal Navy, Army and RAF sections, the CCF offers pupils the opportunity to develop qualities of leadership and self-reliance. In addition to a weekly programme of activities, there are opportunities to join numerous adventurous training camps and courses both during the holidays and at weekends. In recent years, cadets have successfully completed courses such as canoe instructor, winter mountain skills in the Cairngorms, PADI diving, multi-pitch climbing in Spain and the prestigious Rocky Mountain leadership camp in Canada.
Although boys and girls wear Services uniform (provided for them) for certain activities, the CCF is not a specifically military or recruitment organisation: its aims are similar to any of the uniformed youth groups, with the advantage of access to specialised training teams and equipment which the others do not enjoy. All pupils in Senior 3 must join the CCF and there is a high retention rate in later years when participation is voluntary. The CCF enhances the values of service and teamwork that are real strengths of the school.
