BCS Sixth Formers are provided with many opportunities to develop their skills for life and forge friendships beyond the classroom. The beginning of the Sixth Form starts with a team building event, where students from both Years 12 and 13 enjoy a day together getting to know each other. This is often off-site, previous team building days have included Ninja Warrior activity centre in Southampton.

Extra-curricular trips are available throughout the year, these have previously included New York, Skiing and a Visual Arts Trip to London. There is a busy co-curricular offering for students to involve themselves in. With many students taking part in the school productions and competing for sports academies there is never the time to not be challenged or busy! Other examples include Code Club, Landscape Painting and Beginners Cooking. These opportunities allow students to gain something which enhances their educational experience and provide a respite from their studies.

BCS Sixth Formers are also encouraged to get involved in leading areas of school life. This might include delivering assemblies or leading co-curricular activities focused on particular interests. Towards the end of Year 12, students can apply for positions of responsibility. These include Heads of Schools, Deputy Heads of School, Prefects and Heads of Boarding. These leadership positions offer rewarding opportunities to mentor younger students, organise charity events, lead the student council as well as coordinate the annual Sixth Form Summer Ball.

Last year Year 12 took part in the Dorset Mud Run - a 6km obstacle course. In addition to having lots of muddy fun, Year 12 developed organisation and fundraising skills resulting in raising over £1000 for the Elizabeth Foundation. The Elizabeth Foundation is a small charity that supports children with deafness which Year 12 voted to raise money for.

Each year the Sixth Form choose different venues for the annual Summer Ball and it is reflection of the current cohort. It is a celebration of the end of Sixth Form at BCS for our Year 13s but both year groups attend. In 2024 the Sixth Form Summer Ball took place at a beachside venue.
