The Requirement That Costs Students Their Diploma Every Year
Every year, a small number of IB students who have worked hard for two years, sat all their examinations, and achieved strong academic results do not receive their IB Diploma. The reason is not examination failure. The reason is incomplete CAS. Creativity, Activity, Service — the non-academic component of the IB Diploma — is a pass/fail requirement, and failure to complete it means non-award of the full Diploma regardless of academic performance.
This is not a bureaucratic technicality. CAS is a genuine educational requirement designed to ensure that IB students develop as full human beings — not just as examination machines. The IB's view is that a person who can score 45 points but who has spent no time on creative pursuits, physical activity, or service to others during their two most formative years is not fully educated. Whether or not you share this educational philosophy, the practical requirement is unambiguous: CAS must be completed, documented, and signed off by your CAS supervisor before you can receive your Diploma.
What CAS Actually Requires — The Misconceptions Cleared
The IB removed the specific hour requirement for CAS in 2015. The current requirement is not a minimum number of hours but evidence of sustained engagement across all three strands — Creativity, Activity, and Service — demonstrating the achievement of the seven CAS Learning Outcomes. The Learning Outcomes are: identifying own strengths and areas for growth, demonstrating that challenges have been undertaken, demonstrating how to initiate and plan CAS experiences, showing commitment to and perseverance in CAS experiences, demonstrating the skills and recognising the benefits of working collaboratively, demonstrating engagement with issues of global significance, and recognising and considering the ethics of choices and actions.
The documentation requirement is real and consequential. Students who complete genuine CAS experiences but fail to document them adequately — reflective journals, evidence of Learning Outcomes achievement, supervisor sign-off — are in the same position as students who did not complete CAS at all. Keep your CAS portfolio up to date throughout the programme, adding reflections within one week of each significant CAS experience.
CAS experiences must be new — they must involve learning, challenge, or development that goes beyond what the student already does comfortably. Playing cricket in school teams when you have played cricket since age 8 at a high level does not constitute CAS Activity unless you are taking on a new challenge within cricket (coaching others, leading the team, developing a new skill). Starting a new sport, taking on a leadership role in an existing activity, or applying existing skills in a new context that challenges you — these constitute genuine CAS. The question to ask about any proposed CAS experience is: "Will I genuinely grow from this? Will I be challenged? Will I learn something about myself or about others or about the world?"
50 Genuine CAS Ideas Across All Three Strands
For Creativity, ideas that genuinely develop creative skills and challenge students: learning a musical instrument from scratch, composing original music for a school production, writing and directing a short film, creating a podcast series on a topic of genuine interest, designing and building a functional website for a local organisation, developing a mobile application to solve a real community problem, writing and publishing a short story collection, learning calligraphy or a traditional art form, designing the visual identity for a school event, and creating an illustrated educational resource for younger students.
For Activity, ideas that involve sustained physical exertion and personal challenge: training for and completing a half-marathon (not a competitive event but a personal achievement run), learning to swim as a non-swimmer, joining a martial arts class and progressing through belt levels, participating in a mountaineering or trekking programme, learning yoga and developing a consistent practice, joining a competitive sports team you have never played in before, completing a cycling challenge across a significant distance, taking up rock climbing at a climbing centre, learning competitive rowing, and joining a hiking club that tackles progressively more challenging terrain.
For Service, ideas that genuinely benefit communities and develop social awareness: establishing a weekly tutoring programme for students in under-resourced schools, creating and running an environmental awareness campaign in your local community, volunteering consistently at a hospital, disability support centre, or elderly care home, fundraising and implementing a specific project for a local school or community organisation, teaching digital literacy skills to elderly community members, organising a community clean-up and waste management awareness programme, running free language classes for migrants or refugees, supporting a local NGO's communications and outreach through your skills, establishing a peer counselling or study support programme at your school, and creating multilingual educational materials for a community with language access challenges.
