Evidence

Why Evidence Matters 

Your CAS portfolio is your proof that you have genuinely engaged in Creativity, Activity, and Service throughout your IB journey.

• It shows growth: how you developed skills, attitudes, and balance.

• It demonstrates authenticity: that the experiences and reflections are your own.

• It prepares you for your final CAS interview and potential IB checks.

• It helps you remember everything you’ve achieved — and celebrate it!

What Counts as Evidence 

Evidence can be anything that shows your involvement and learning. Be creative and varied.
Here are some ideas:

• Photos or short videos (from rehearsals, games, events - always respecting consent and privacy rules)

• Certificates or awards (e.g., sports tournaments, art exhibitions, language exams)

• Posters, programs, or tickets (for events you helped organise or participated in)

• Screenshots (emails or messages confirming participation, social media posts about your event)

• Plans or meeting notes (for CAS Projects or regular activities)

• Examples of your work (a painting, a song you composed, a blog post, etc.)

• Reflection artifacts (journal entries, video diaries, or a voice note about what you learnt)

Supervisor Form 

If your experience is supervised by an adult — for example:

• Your sports coach

• Your music teacher

• Your volunteer supervisor

They must sign the official CAS Verification Form.

This form confirms your participation and helps validate your portfolio for IB checks.

Quick Tips 

• Quality over quantity: 1–2 strong pieces of evidence per experience is enough.
  
  

• Respect privacy: Avoid sharing images of other students without permission.
  
  

• Upload regularly: Don’t wait until Year 13 - update as you go!
  
  

• Match evidence with reflections: A photo is great, but a reflection explaining what you learned is even better.
