How Does CAS Get Verified in the IB System?
Completing CAS—Creativity, Activity, and Service—is a non-negotiable part of the IB Diploma. While CAS isn't graded, failure to meet its expectations can result in not receiving the diploma. So how exactly does IB verify CAS? And what can you do to ensure everything checks out? This guide breaks it all down—with direct links to trusted RevisionDojo resources.
1. Who Verifies Your CAS Activities?
Verification starts at your school. Your CAS Coordinator—not the IB itself—monitors your activities, reflections, and project completion over the 18-month duration. The school submits your status (complete/incomplete) to the IB via IBIS.
To understand the full expectations, check out RevisionDojo’s guide on CAS minimum requirements, which outlines what qualifies as a legitimate CAS experience.
2. What Does Verification Involve?
To “complete” CAS, students must:
- Show evidence of consistent CAS engagement
- Complete a CAS project (minimum one month)
- Demonstrate all seven learning outcomes
- Participate in three formal interviews with the CAS Coordinator
RevisionDojo’s CAS checklist for IB students offers a step-by-step planner to help meet every checkpoint.
3. How Do Reflections and Evidence Matter?
IB requires quality reflections, not just logs. Students must explain:
- What they learned
- How they overcame challenges
- How they collaborated or showed commitment
