CAS can feel like the one part of the IB that refuses to stay in its lane.
You sit down to revise. You open your notes. And then your brain remembers you also promised someone you’d "draft a plan" for a charity event, record a reflection, and find a supervisor signature. Suddenly, your neat exam schedule looks like a paper boat in a storm.
The secret is not to do "more" CAS. It’s to choose CAS experiences and a CAS project that are naturally sustainable during IB exam prep. That means simple logistics, real learning, and reflections you can write while your memory is still warm.
A quick IB CAS checklist (so your ideas actually work)
Before you commit, run every idea through this filter. It will save you weeks.
-
Does it fit Creativity, Activity, or Service clearly? (Better if it overlaps strands.)
-
Can you do it consistently for 4+ weeks? A CAS project needs at least a month of planning and execution.
-
Does it create real evidence? Photos, agendas, drafts, attendance sheets, feedback.
-
Can you describe growth? Skills, challenges, decisions, collaboration.
-
Will it survive exam season? If it requires seven meetings a week, it won’t.
If you’re unsure what qualifies, read What Is CAS (Creativity, Activity, Service)? and double-check the minimum requirements for CAS in the IBDP.
CAS project vs CAS experience (choose the right size)
Many IB students lose time by building a project when they only needed an experience, or by logging experiences that don’t add up to a coherent project.
A CAS experience can be one-off or ongoing, but it still needs reflection and evidence. A CAS project is longer-term, collaborative, and lasts at least one month.
If you want a clean distinction (and less coordinator back-and-forth), use this guide: What Counts as a CAS Project vs. a CAS Experience?.
Creativity CAS ideas (high impact, low chaos)
These creativity options work well for IB students because they create natural artifacts: drafts, designs, recordings, scripts.
Mini-documentary series: “One local issue, five short episodes”
Pick a topic you genuinely care about (food waste, transport access, local history). Create 3--5 short episodes, each under three minutes.
-
Strands: Creativity, Service (often)
-
Why it works for IB: Clear planning, measurable skills growth (editing, interviewing), easy evidence.
Student revision zine or newsletter (not a full newspaper)
A full newspaper dies under deadlines. A small monthly zine survives.
-
Strands: Creativity, Service
-
Tip: Feature student stories about study habits, wellbeing, and community efforts. Keep it tight.
“Teach one creative skill” workshop
Run a beginner workshop: photography basics, Canva design, creative writing prompts, or simple music composition.
-
Strands: Creativity, Service
-
Evidence: Slides, attendance list, feedback forms, your lesson plan.
School exhibition with a theme: “small work, real meaning”
Instead of a huge gallery event, curate a themed exhibit in a hallway, library corner, or online gallery.
-
Strands: Creativity, Service
-
Ethical angle: inclusivity, representation, accessibility.
Activity CAS ideas (that don’t steal revision time)
Activity is where IB students often overcommit, then stop, then panic-log. Choose something repeatable.
Charity run or walk with a simple structure
One event. One route. One cause. One post-event reflection.
-
Strands: Activity, Service
-

“Micro-team” sports club
A full league is a logistical monster. A micro-team is sustainable: 8--12 people, weekly practice, occasional friendly games.
-
Strands: Activity, Service
-
Learning outcomes: collaboration, perseverance, leadership.
Outdoor sessions with an environmental purpose
Monthly hike + short trail cleanup. Or a beginner-friendly climbing day with safety planning.
-
Strands: Activity, Service
-
Evidence: route plan, safety checklist, photos, reflections.
Dance or movement challenge (with coaching)
Host a short dance marathon fundraiser, or run weekly beginner sessions (stretching, basic choreography, mobility).
-
Strands: Activity, Service
-
Why it works: clear progress markers, easy collaboration.
Service CAS ideas (real service, not performative service)
Service is strongest when it’s consistent and specific, not when it’s a one-time “big gesture.”
Tutoring program with a narrow promise
Don’t offer to tutor “everything.” Offer one subject, one year group, one weekly slot.
-
Strands: Service, Creativity
-
Evidence: lesson outlines, attendance, anonymized improvement feedback.
Elderly outreach with a repeatable activity
Reading sessions, tech help, board games, short walks. The key is routine.
-
Strands: Service, Activity
-
Ethical angle: privacy, dignity, consent for photos.
Environmental awareness campaign (small but consistent)
A weekly “one change” campaign: recycling clarity posters, waste audits, a social media series, or lunchroom sorting support.
-
Strands: Service, Creativity
-
Evidence: posts, designs, data (even simple counts).
Fundraising with transparency
Bake sales are fine if you track where the money goes and reflect on impact.
-
Strands: Service, Creativity
-
Tip: Show budgeting, permissions, and outcomes.
The IB-friendly way to document CAS without burning out
CAS fails most often on documentation, not on effort.
If you’re drowning in admin during IB revision season, steal a system from people who stay calm: fixed windows and small reflections. This pairs well with Balancing CAS With Real Life (Without Burning Out).
A practical approach:
-
Do the experience (keep it short and real)
-
Capture evidence immediately (one photo, one artifact, one note)
-
Write a short reflection same day (six sentences is enough if it’s honest)
Schools verify CAS through your coordinator and portfolio processes, so don’t guess about what they need. Use: How Does CAS Get Verified in the IB System?.

A calm ending: let CAS support your IB, not sabotage it
