What does a balanced CAS programme look like?

The core of a balanced programme

  • A balanced programme—a meaningful and well-distributed mix of creativity, activity and service—is a mandatory requirement for the IB Diploma

    • Students are required to engage with all three strands regularly for at least 18 months

  • Balance ensures that a student's development is holistic—an educational approach that addresses physical, social, emotional and cognitive well-being

  • Students should avoid over-emphasising a single strand, as this weakens the overall learning process and personal growth

Variation in experiences

  • The programme should include a combination of CAS experiences—specific events or series of events where you engage with the strands—that are both planned and spontaneous

  • A meaningful programme must consist of more than just a series of unplanned or singular events

  • Students should participate in both short-term singular events and sustained experiences—continuous or ongoing actions that take place regularly over an extended period

The requirement for a CAS project

  • Every student must complete at least one CAS project—a collaborative series of sequential experiences lasting at least one month

    • The project must involve teamwork and can integrate two or all three of the CAS strands

    • This significant project ensures that students demonstrate leadership, initiative and perseverance through sustained collaboration

How can students plan and check for balance?

Using the CAS portfolio for planning

  • The CAS portfolio—a collection of evidence and reflections that showcases a student's journey—is the primary tool for planning balance

    • Use your CAS portfolio planning/initial planning area (whatever your school uses) to map interests

    • Mapping interests helps to identify which strands may need more focus to ensure an equal distribution of experiences

Practical monitoring strategies

  • Students can map their experiences across a calendar to visualise their commitment over the 18-month period

  • Labelling each activity by its specific strand allows for a quick review of the programme's distribution

  • Regular self-reviews should be conducted to identify if one strand—such as Creativity—is underrepresented

Adjusting and maintaining engagement

  • If a student notices a lack of balance, they should adjust their plan by initiating new experiences in the missing strand

  • A strong plan involves mixing different types of engagement monthly, such as combining creative projects, physical challenges and community service

  • During the three formal interviews—documented dialogues with a CAS coordinator or adviser—the balance of the programme will be reviewed and discussed

    • A CAS coordinator is the staff member responsible for overseeing the school's CAS programme and reporting student progress
