At the heart of the IB philosophy, Creativity, Activity, Service (CAS) is a compulsory component of the IB Diploma course.
 It recognises the importance of life outside the world of scholarship, providing a refreshing counterbalance to academic studies.
 By fulfilling the CAS element, IB students are able to present to university admissions tutors a truly rounded CV.

What does it involve?

IB students must take part in activities under the three strands of CAS:

Creativity – Any experience that involves creative learning and thinking, for example Art, Music or Drama.
Activity - Physical exertion contributing to a healthy lifestyle, complementing academic work elsewhere in the Diploma Programme.

Service - An unpaid and voluntary exchange that has a learning benefit for the student.

Pupils must take part in two activities under each heading and prove that they are participating in CAS activities weekly. 
Students must also be involved in at least one project involving teamwork of significant duration.

Student development

CAS seeks to achieve demonstrable development in pupils. To ensure this, students’ individual CAS programmes should involve real, purposeful activities with significant outcomes. Tasks must extend the student and involve thoughtful consideration such as planning and reviewing. Reflection on outcomes achieved and personal learning must take place.


Over the two years, students need to show evidence that they have achieved all seven of a set of outcomes which includes: increased awareness of their own strengths and areas for growth; undertaking new challenges; planning and initiating activities, worked collaboratively with others; show they have considered the ethical implications of their actions; demonstrate commitment and perseverance as well as global engagement.


examples of CAS activities 

At St Leonards, in recent times our IB students have taken part in a range of activities as part of CAS. 

  • Helping in St Leonards Junior School.
  • Tree planting and conservation projects.
  • Helping in local charity shops.
  • Duke of Edinburgh expedition training and assessed expeditions.
  • Riding for the Disabled.
  • Taking up a new musical instrument or organising a concert.
  • Helping to teach languages to non-native speakers in local schools.
  • Helping to set up and coach sports teams.


At St Leonards we use an online management system called 'ManageBac’ to help the students keep a record of their CAS programme over the two years. This enables them to plan all endeavours and contact supervisors and advisors easily. The pupils reflect on each activity in any form they choose, be it through a word document with photos, a PowerPoint presentation, a blog, or a film, which is then uploaded to their CAS file on ‘ManageBac’.
