CAS, creativity, activity and service, is the part of the IB Diploma where you are meant to do, not just study. Done as a box-ticking exercise, it is forgettable. Done well, a CAS project can be the most real thing on your entire application. The difference is almost always the idea you start with.
What makes a CAS project strong
A strong CAS project usually does three things at once. It addresses a real need rather than an invented one. It requires you to take initiative and make decisions, not just show up. And it produces evidence, so you and your supervisor can see what actually happened. Keep the seven CAS learning outcomes in mind as you choose, especially the ones about identifying your own strengths, undertaking new challenges, showing perseverance, and engaging with issues of global significance.
The simplest test: could you explain, a year later, what changed because you did this? If the honest answer is "nothing, but I completed it," pick a better idea.
CAS project ideas across creativity, activity and service
Service ideas with real impact
- Run a household waste-segregation drive in one neighbourhood, and actually measure whether segregation rates change.
- Build a small, useful tool for a local NGO, a simple database, a booking sheet, a website, and hand it over working.
- Set up a peer-tutoring programme for a specific subject younger students struggle with, and track their results over a term.
- Map an accessibility problem in your community, missing ramps, unsafe crossings, and document it well enough to take to the authorities.
Creativity ideas that are more than a hobby
- Design and produce a public awareness campaign on a real local issue, and measure whether it reached anyone.
- Create an original piece, a short documentary, a data visualisation, a piece of writing, about a community you actually spent time with.
- Build something, an app, a device, an installation, that solves a problem someone genuinely has.
Activity ideas with a purpose
- Organise a sustained fitness or sport initiative for a group who wouldn't otherwise have access, and see it through, not a one-off event.
- Combine activity with service: a clean-up that is measured, a walkathon that funds something specific and verifiable.
The best CAS projects aren't bigger. They're realer. A small project with measured results beats a grand one with none.
How to make a CAS project actually count
Here is the step most students miss. Whatever you do, document it so the work is verifiable, not just described. Photos, data before and after, a short written record, a public page. This matters for two reasons. It makes your CAS reflection far stronger, because you are reflecting on real evidence. And if the project is genuinely good, that same evidence becomes something you can point a university to later, which almost no CAS project ever becomes.
Turn your CAS project into a verifiable public record. Most CAS work disappears into a school portfolio. A documented, checkable record of real impact is the rare version that keeps working for you long after the reflection is submitted.
Where FIELDWORK fits
FIELDWORK is built for exactly this. It takes a real project, runs it through a rigorous four-phase method, from field mapping to a deployed, measured result, and ends in a permanent public record a university can verify. It is designed to map onto CAS, so the fellowship and your CAS requirement become the same body of work rather than two separate obligations. The programme is application-only and spans any field you care about, and its model sits within the UNFCCC Global Innovation Hub Systemic Innovation Workshop.
If you want your CAS project to be the real thing on your application rather than a line you completed, that is the entire point.
