How many CAS hours should I complete in my first term?

The IB does not prescribe a universal first-term CAS hour target. Completion focuses on sustained engagement, a reasonable balance across the three strands, the CAS project, and evidence of the seven learning outcomes. Your school may still ask you to record hours or meet local participation targets. In September-November, regular involvement is more useful than accumulating a large number of disconnected hours. Confirm any numerical expectation with your CAS coordinator because it may be a school procedure rather than an IB-wide rule.

Do I need to cover all seven CAS learning outcomes by November?

You do not normally need to demonstrate all seven learning outcomes during the first term unless your school sets that local deadline. The outcomes should emerge across your full CAS programme, and each must eventually be supported by convincing evidence. Trying to force every outcome into early experiences usually creates superficial claims. During the first term, focus on understanding the outcomes and documenting the few that genuinely arise. Keep a simple tracker so you can identify gaps later without turning CAS into a checklist.

How often should I write CAS reflections?

The IB does not impose one universal number of reflections or a standard word count for every student. Reflection should occur at meaningful points, including moments of challenge, discovery, change, success, or difficult decision-making. A sustained experience usually needs reflections at more than one stage so that development over time becomes visible. Short, specific entries written promptly are generally more useful than a long retrospective account. Follow your school's platform, frequency, and format requirements because coordinators may establish local deadlines.

Can an activity count for more than one CAS strand?

Yes, one experience can address more than one strand when each connection is genuine. Organizing and participating in a charity dance event, for example, might combine Creativity, Activity, and Service. Simply adding multiple labels does not make the connections valid. Your description and evidence should show what you created, what physical exertion occurred, and how the work responded reciprocally to an authentic community need. Ask your coordinator if the classification is unclear before relying on it for portfolio balance.

Must I start my CAS project during the first term?

The IB requires at least one CAS project, but it does not set a universal rule that every student must begin it by November. Schools may create their own proposal or completion deadlines, so check your calendar and handbook. The project must be collaborative and last at least one month from planning through completion. Even if you do not launch it during the first term, you can investigate a need, identify collaborators, and test whether the idea is realistic. Early planning reduces the risk of trying to create a rushed project during a busy assessment period.

What counts as good evidence for a first-term CAS portfolio?

Useful evidence can include photographs, drafts, schedules, training records, meeting notes, correspondence, creative products, participant feedback, or supervisor confirmation. Evidence should support a claim rather than merely prove that you appeared somewhere. For example, a revised event plan can demonstrate how you responded to a logistical problem more effectively than a posed photograph. Protect other people's privacy and obtain appropriate permission before uploading identifiable images or sensitive information. Pair each artefact with a reflection explaining what it reveals about your decisions, learning, or development.

Common CAS Mistakes Students Make in Their First Term

IB Diploma CAS IB Study Guides

• 12 Oct 2026•9

The most common CAS mistakes students make in their first term are postponing documentation, treating CAS as an hours checklist, overcommitting, writing descriptive reflections, and misunderstanding the CAS project. These problems are manageable early in DP1 but become harder to repair once academic deadlines intensify.

CAS is not numerically graded, but it is a required part of the Diploma Programme core. Students must participate regularly, maintain a portfolio, complete at least one collaborative CAS project, and provide evidence for the seven CAS learning outcomes. This guide explains how to establish those foundations during September-November.

What CAS requires across the Diploma Programme

The official IB overview of creativity, activity, service defines three strands:

Creativity: exploring and extending ideas that lead to an original or interpretive product or performance.
Activity: physical exertion contributing to a healthy lifestyle.
Service: collaborative and reciprocal engagement with a community in response to an authentic need.

CAS normally continues for at least 18 months, with regular engagement and a reasonable balance among the strands. Completion depends on evidence of the learning outcomes, not a universal number of hours. Schools may set local checkpoints, deadlines, or documentation procedures, so distinguish IB requirements from school-specific rules.

The official CAS subject brief explains that the portfolio records experiences, reflections, and supporting evidence. Although it receives no numerical mark, your school uses it to determine whether you completed CAS.

The most common CAS mistakes students make

Waiting for the perfect experience

CAS experiences do not need to be international, unusual, or large-scale. A sustained running programme, school publication, music arrangement, or weekly tutoring commitment can support meaningful learning when it involves purpose, challenge, and reflection.

Begin with one or two manageable experiences that fit your timetable. You can adjust them after learning what is sustainable.

Treating CAS as an hours competition

Hours may help record participation, especially if your school requests them, but they do not prove learning. Attendance without evidence of planning, challenge, decision-making, or development creates a weak portfolio.

Ask what you hope to achieve, which learning outcome genuinely applies, and what evidence could demonstrate your progress. For further clarification, see how CAS is marked in the IB Diploma.

Joining too many activities

Students sometimes register for numerous clubs, sports, and service opportunities before understanding the demands of six subjects, TOK, and the Extended Essay. A stronger first-term plan uses two or three sustainable anchor experiences.

Depth makes it easier to demonstrate perseverance, skill development, and reflection over time. If scheduling is difficult, use a realistic approach to balancing CAS with academic work.

Assuming every extracurricular activity counts

An activity may be worthwhile without qualifying as an appropriate CAS experience. Passive attendance, routine obligations, or experiences without meaningful personal engagement may not satisfy your school's expectations.

Before committing, explain your role, goal, proposed strand, and possible learning outcomes to your coordinator. Approval procedures vary, so early confirmation is safer than retrospective justification.

Writing descriptions instead of reflections

“I attended football practice and completed several drills” records an event but says little about learning. Effective reflection examines a difficulty, decision, changed assumption, emotional response, or next step.

Use these prompts:

What significant moment occurred?
What was difficult or unexpected?
How did I respond, and why?
What did this reveal about me?
What will I change next time?

The guide to what coordinators want in CAS reflections provides practical examples. Reflections need not be long essays after every session unless your school requires that format.

Postponing evidence and forcing learning outcomes

Delayed documentation produces vague reflections and missing photographs, drafts, schedules, feedback, or meeting notes. After a significant session, save one relevant artefact and write a short note while the details remain fresh. RevisionDojo's guide to strengthening CAS documentation offers a repeatable process.

Do not claim every learning outcome for every activity. Select only outcomes supported by your evidence. Across the complete programme, however, you must provide evidence for all seven outcomes at least once.

Confusing an experience with the CAS project

A CAS experience may be individual or collaborative, short or sustained. The required CAS project is collaborative, consists of sequential experiences, and lasts at least one month. It may involve one, two, or all three strands.

The official CAS project guidance emphasizes initiative, perseverance, collaboration, problem-solving, and decision-making. You may not need to begin the project in your first term unless your school requires it, but this is a sensible time to investigate needs and identify collaborators. Review the distinction between a CAS project and CAS experience before labelling your work.

Planning service without investigating need

Service should respond to an authentic need and respect the community's dignity, autonomy, and perspective. Before organizing a donation drive, for example, ask the community partner what is needed, whether storage exists, and how items should be collected. Investigation prevents waste and creates stronger evidence of planning and ethical decision-making.

A practical September-November CAS plan

This is a recommended routine, not an official IB deadline schedule.

Period	Practical priorities	Evidence to retain
September	Learn school procedures and begin 1-2 sustainable experiences	Goals, approvals, schedules, baseline evidence
October	Participate regularly and reflect on meaningful moments	Dated reflections, drafts, photographs, feedback
November	Review workload and explore a collaborative project	Progress evidence, meeting notes, project outline

By November, aim for a reliable routine rather than a completed programme. You should understand where documentation belongs, maintain at least one sustained commitment, and recognize how authentic learning outcomes emerge.

First-term CAS checklist

Check that you have:

Read your school's CAS instructions.
Chosen experiences that fit at least one strand.
Created a sustainable weekly commitment.
Stored dated evidence promptly.
Reflected on decisions, learning, or change.
Discussed local deadlines and approvals.
Begun considering project ideas and collaborators.

If you are behind, document a recent meaningful experience, contact your coordinator, and establish a small weekly routine. Never invent retrospective details.

Conclusion

Avoiding common first-term CAS mistakes requires consistency rather than an impressive list of activities. Choose manageable experiences, confirm school procedures, collect evidence promptly, reflect honestly, and investigate your collaborative project early.

RevisionDojo's CAS reflection guidance can help structure this routine. Use it to prompt personal thinking while keeping every final reflection accurate and grounded in your own experience.
