How long does an IB CAS project need to last?

An IB CAS project must last at least one month from initiation to completion. It should consist of a collaborative series of connected CAS experiences rather than one isolated activity. Investigation, preparation, action, reflection, and demonstration may all contribute to the project timeline. A final event can form part of the project, but the event alone does not demonstrate a month-long process. Your CAS coordinator should confirm that the proposed schedule meets your school's expectations before you begin.

Does a CAS project have to include Service?

No, an official CAS project may address Creativity, Activity, Service, or a combination of strands. A collaborative theatre production could therefore qualify through Creativity, while a sustained group fitness initiative might focus on Activity. However, a project described as community service must respond to an authentic need and benefit the community as well as student learning. Combining strands can create useful opportunities, but it is not automatically more valid than a focused single-strand project. Choose the strand classification that accurately reflects what participants will do.

How can I tell whether a community need is authentic?

An authentic need is confirmed through investigation and communication with the community rather than assumed by the student team. Speak with potential participants, local organisations, staff members, or other informed representatives. Use interviews, observations, surveys, or reliable local information to understand the issue and existing responses. Ask what support would be useful, what has already been tried, and what constraints or ethical concerns exist. If the community has no meaningful role in identifying the need, your proposal probably requires further investigation.

Can fundraising count as a CAS project with community impact?

Fundraising can contribute to a CAS project, but collecting money alone does not guarantee meaningful impact. Your team should investigate why funds are needed, collaborate with an appropriate organisation, and communicate honestly about how the money will be used. The project also needs a connected sequence of collaborative experiences lasting at least one month. Evidence might include budgeting, campaign design, permissions, team decisions, verified transfer of funds, and feedback from the partner. Consider whether direct service, advocacy, or another form of support would be more useful than fundraising.

What should I do if my CAS project is not producing the expected results?

Treat unexpected results as evidence to investigate, not as something to conceal. Review your baseline, participation data, observations, and feedback to identify what may be limiting the project. Discuss possible changes with your community partner and team rather than changing the plan unilaterally. Record the decision, the evidence behind it, and what happens after the adjustment. Thoughtful adaptation can demonstrate planning, collaboration, perseverance, and consideration of ethical consequences more convincingly than pretending the original plan worked perfectly.

What evidence should I collect for a community-focused CAS project?

Collect evidence that shows both the project process and what changed. Planning documents, meeting notes, role allocations, drafts, attendance records, partner feedback, and anonymised participant responses can all be useful. Photographs may support the record, but only when taking and storing them is appropriate and consent has been obtained. Include reflections on important decisions, obstacles, collaboration, ethical questions, and changes made after feedback. Evidence should substantiate your learning and contribution without exploiting community members or exaggerating the project's impact.

How to Choose a CAS Project With Real Community Impact

IB Diploma CAS IB Study Guides

• 11 Oct 2026•9

To choose a CAS project with real community impact, begin with a verified community need rather than an activity you assume people will value. Speak with those affected, identify a useful role for your team, and design a collaborative response that you can sustain and evaluate.

September-November offers a practical structure: investigate in September, prepare in October, then begin meaningful action and adjustment in November.

What an IB CAS project must involve

A CAS project is more than a large volunteer activity. According to the IB's official CAS project guidance, every Diploma Programme student must complete at least one CAS project.

Official IB guidance describes it as a collaborative series of sequential CAS experiences lasting at least one month. It may address Creativity, Activity, Service, or any combination of the three strands. Contrary to a common misconception, one project does not have to include every strand.

A suitable project should include:

Collaboration with students, community members, or both
Connected experiences rather than one isolated event
At least one month from initiation to completion
Purposeful planning, action, reflection, and evidence
Opportunities for challenge and personal development

When Service is involved, the response should address an authentic community need through reciprocal engagement. The IB overview of Creativity, Activity, Service also emphasizes initiative, perseverance, collaboration, problem-solving, and decision-making.

Your school decides whether a proposal is appropriate. Obtain approval from your CAS coordinator before spending money, collecting personal information, or promising support to an organisation.

Start with a need, not an event

Students frequently begin with an event such as a fundraiser, clothing drive, awareness account, or tutoring club. A stronger starting question is: What does this community identify as a priority, and what useful role can our team play?

A community may be a school group, neighbourhood, care home, environmental organisation, sports club, or online community. Impact does not require national scale. Reliable homework support for 12 younger students may be more valuable than a large campaign producing no observable benefit.

Investigate by interviewing an informed representative, consulting potential participants, observing existing provision, and reviewing reliable local information. Ask what has already been attempted and which practical, cultural, or ethical constraints must shape your response.

The IB's service learning stages resource connects investigation, preparation, action, reflection, and demonstration. These stages help prevent students from rushing into action based on assumptions.

Use a five-part project test

Compare each possible project against five criteria.

Test	Question to ask
Need	Has the intended community confirmed that this matters?
Partnership	Will community members influence goals and decisions?
Feasibility	Can the team deliver safely with available time and resources?
Learning	Will the work create genuine challenge and collaboration?
Impact	Can the team observe a useful change without exaggeration?

Reject ideas that depend mainly on assumptions. Generic mental-health posters, for example, may appear helpful, but a counsellor or qualified organisation should advise what information is needed, which language is appropriate, and where students can obtain professional support.

Feasibility matters as much as ambition. A focused six-week reading programme with reliable attendance is stronger than a proposed city-wide literacy campaign that never moves beyond social media.

Plan your IB CAS fall term

A realistic IB CAS fall term plan leaves time for investigation and partnership before action.

Period	Main task	Useful evidence
Early September	List interests, skills, communities, and constraints	Personal inventory and initial ideas
Late September	Contact partners and investigate needs	Emails, interview notes, observations, or surveys
October	Agree on goals, roles, safeguarding, and measures	Approved proposal, timeline, budget, and risk plan
November	Deliver initial action, collect feedback, and adjust	Attendance, anonymised feedback, work samples, and reflections

Plan around academic deadlines from the outset. RevisionDojo's guide to balancing CAS with academics can help you set manageable weekly commitments. The one-month requirement covers the connected project process, not necessarily four identical action sessions.

Define impact before taking action

Outputs describe what your team delivered. Outcomes describe what changed. Four tutoring sessions are an output; greater participant confidence with specified skills may be an outcome.

Choose one modest outcome and establish a baseline. Before digital-skills sessions, for example, ask participants which tasks they can complete independently, then repeat the questions afterwards. Attendance, participant feedback, completed products, observed skill development, and requests to continue may provide useful evidence.

Do not claim that a small project “solved” poverty, isolation, or climate change. Honest evidence of a limited contribution is more credible and ethically responsible than unsupported claims.

Design with the community and collect useful evidence

Real impact depends on reciprocity. Partners should help define the goal, methods, timing, accessibility, safeguarding arrangements, consent procedures, and appropriate measures of success. They should also influence adjustments when feedback shows that something is not working.

For example, do not independently collect donations and assume they will help. Ask an organisation which items are needed, in what condition, and how distribution operates. Sorting, transport, translation, or targeted purchasing may be more useful than collecting large quantities of unsuitable goods.

Your CAS portfolio is not formally graded, but it should demonstrate engagement and progress toward the seven learning outcomes. RevisionDojo's guide to CAS projects and experiences explains why sustained collaboration differs from a one-off activity.

Useful evidence includes meeting notes, changing plans, role allocations, partner feedback, drafts, attendance records, anonymised responses, and photographs taken with appropriate consent. Reflect when something significant occurs, such as conflict, an ethical concern, an unexpected result, or a change of plan. The guide to meaningful CAS reflections shows how to move beyond description.

Common mistakes that weaken impact

Avoid choosing an impressive cause without local evidence, measuring visibility instead of benefit, or asking a partner merely to approve a finished plan. Views and poster numbers are outputs, not proof that understanding or behaviour changed.

Plan a responsible ending by transferring resources, documenting procedures, identifying a successor, or explaining why the work will stop. Do not force all seven learning outcomes into one project; connect reflections only to outcomes genuinely supported by evidence.

Conclusion

Choose a CAS project by verifying a need, working collaboratively, setting a feasible goal, and distinguishing outputs from outcomes. A small project designed with a community can have more responsible impact than an ambitious project based on assumptions.

RevisionDojo's CAS project ideas and planning guide can help you compare manageable formats, while its reflection guidance can help you document meaningful decisions throughout the project.
