The CAS Strands (DP IB Creativity, Activity, Service): Revision Note

What are the CAS strands and why are they essential?

The three pillars of CAS

• The programme is built on three strands—specific areas of focus that categorise all CAS experiences

  • The three strands are Creativity, Activity and Service

• These strands form the foundation of CAS and aim to develop different aspects of a student's character

  • Creativity focuses on developing creative and intellectual abilities

  • Activity focuses on physical well-being and a healthy lifestyle

  • Service focuses on social and ethical engagement with the community

The requirement for balance

• Students are expected to engage across all three strands over the duration of CAS (minimum 18 months), ideally on a weekly basis, maintaining a reasonable balance

• A balanced programme involves a meaningful mix of all three strands rather than over-emphasising just one

• There is a common misconception that a single activity can "cover everything"—true balance requires varied experiences over time

  • Balance comes from a range of experiences over time; some experiences may combine strands, but you still need breadth across your programme

• Balance ensures that your learning is holistic—addressing your physical, social, emotional and cognitive development

What do Creativity, Activity and Service involve?

Creativity

• Creativity involves exploring and extending ideas that lead to an original or interpretive product or performance

  • It encourages you to move beyond the familiar and explore unconventional thinking—approaches that are creative, original or non-traditional

• Creative expression is limitless and can include visual arts, music, drama, design, film, culinary arts or writing

• It is not enough to simply appreciate the creative efforts of others, such as visiting a museum or attending a concert

  • You should be an active participant who defines new challenges and goals to improve your skills

Activity

• Activity involves physical exertion that contributes to a healthy lifestyle

• The goal is to promote lifelong healthy habits related to physical well-being

• Pursuits can include individual or team sports, aerobic exercise, dance, outdoor recreation and fitness training

• You are encouraged to participate at a level that provides a genuine challenge—an experience that pushes you beyond your current physical capabilities

  • This may involve setting new personal goals, exploring different training models or starting a brand new sport

Service

• Service is collaborative and reciprocal engagement with the community in response to an authentic need

  • An authentic need is a verified and genuine requirement for assistance identified through research or direct interaction with the community

• Reciprocal engagement means that the experience provides mutual benefits for both the student and the community

  • This ensures the relationship is built on respect and shared commitment rather than just "doing for others"

• Through service, you develop essential social and personal skills such as problem-solving, decision-making and accountability for your actions

• Service experiences must always be unpaid to ensure the focus remains on community contribution rather than financial gain

Analogy: The Three-Legged Stool

• Think of a balanced CAS programme like a three-legged stool

• Each leg represents one of the strands: Creativity, Activity and Service

• If you focus only on one or two legs, the stool becomes unstable and cannot support your growth

• You need all three legs—sturdy and equal—to stand tall and maintain your balance throughout the 18-month journey
