CAS project ideas are student-led plans that combine creativity, activity, and/or service to meet IB CAS expectations while creating real impact in a community. A CAS project is typically collaborative and lasts at least one month, moving through planning, action, reflection, and sharing outcomes.

What counts as an IB CAS project?

  • Duration: sustained for at least one month (from planning to completion).
  • Collaboration: usually involves working with others (students, a club, a community partner).

Tip: The best CAS project ideas start with a real community need and a realistic plan you can sustain week-to-week.

How to Choose the Best CAS Project Idea

  2. Pick your constraints: time available each week, your team size, budget, permissions, and location.
  3. Match strands: decide if your project is mainly creativity, activity, service, or a blend.
  4. Make it sustainable: plan 4–8 weeks of repeatable actions, not a one-day event.
  5. Plan evidence: photos (with permission), materials, feedback, and short reflection checkpoints.

    Frequently Asked Questions About CAS Projects

    chevron

    What is a CAS project?

    A CAS project is a student-led initiative in the IB Diploma Programme that combines creativity, activity, and/or service to address a real need. It typically involves collaboration and lasts at least one month from planning through completion.

    What are the five stages of a CAS project?

    The five stages are investigation, preparation, action, reflection, and demonstration.

    How do you come up with a CAS project idea?

    Start with your interests and a real community need, then choose something you can sustain over several weeks. Confirm you have the time, people, permissions, and resources to follow through, and plan how you will document evidence and reflections.

    How many people should be in a CAS project?

    Some projects can be started individually, but CAS projects are usually collaborative. Working with other students, clubs, or community partners often makes the project more realistic and impactful.

    What counts as an IB CAS project?

    A CAS project is a planned, sustained activity that includes creativity, activity, and/or service and creates a positive outcome for others. It should include planning, ongoing reflection, and a final demonstration or sharing of what you accomplished.

    Can you fail CAS?

    Yes. If a student does not complete the required CAS project and reflections, they may not meet CAS requirements, which can affect whether they receive the IB Diploma.

    What are examples of ambitious CAS projects?

    Ambitious projects are sustained and well-organized, such as running a multi-week tutoring program, building a school-wide sustainability campaign, launching a community arts showcase for a cause, or creating a tech literacy program with a local partner.

    How should I handle unexpected problems during my CAS project?

    Adapt your plan, ask for advice early, and document what changed and why. Problem-solving is part of CAS growth—reflect on challenges, what you tried, and what you learned as you adjust.

    Do I need approval for my CAS project?

    Usually, yes. Students should discuss their CAS project idea with their CAS coordinator or advisor before starting to confirm it meets IB expectations and can be properly supported and documented.

    What should I aim to demonstrate in my CAS project?

    A strong CAS project shows sustained effort, personal growth, and positive impact on others. It should clearly connect your actions to outcomes and include reflections that show learning over time.

    How should I document my CAS project?

    Keep evidence throughout the project—photos (with permission), planning notes, progress updates, feedback, and deliverables—along with reflections at multiple stages. Don’t wait until the end to record what happened.

    Why is reflection important in CAS?

    Reflection shows how you learned from planning, action, setbacks, and outcomes. It helps demonstrate growth, decision-making, and what you would improve if you did the project again.

    How long does a CAS project need to last?

    A CAS project should last at least one month from planning to completion, with ongoing engagement rather than a one-day activity.
