How Many Hours of CAS Are Required?

CAS is not measured by a fixed number of hours. CAS runs across roughly 18 months of the Diploma, with regular, sustained engagement and reflection against learning outcomes. Confirm the current requirements with the school, since IB guidance can be updated.

Can CAS Activities Happen Outside School?

Yes. Many CAS experiences take place beyond the classroom, from community service and sport to creative projects. What matters is genuine engagement and honest reflection. School and out-of-school experiences can both count.

Does CAS Affect My Child's Final IB Score?

CAS is not graded and adds no points to the 45-point total. Completing it satisfactorily, however, is a requirement for the Diploma to be awarded. In that sense, it is essential, even without a score.

What Counts as a CAS Activity?

Activities across the three strands of creativity, activity, and service can count, provided they involve real engagement and reflection rather than box-ticking. A single experience can even span more than one strand. The reflection is as important as the activity.

Which JBCN Campuses Offer the IB Diploma With CAS?

JBCN offers the IB Diploma, including CAS, at Parel, Oshiwara, and Chembur. Each campus follows the same IB Core requirements. Contact your chosen campus for details of its CAS programme.

What Is CAS in the IB Diploma, Parent Guide

What Is CAS in the IB Diploma: A Parent's Guide to Creativity, Activity and Service

Parents new to the IB Diploma often pause at one part of it, CAS, because it is not a subject and carries no exam. Yet Creativity, Activity, Service is one of the programme's three Core requirements, and it shapes a learner as much as any subject does. Understanding what CAS asks for, and why, makes the whole Diploma clearer.

The guide explains the concept, the three strands, how it is assessed, and what it looks like in practice.

What Is CAS in the IB Diploma?

CAS stands for Creativity, Activity, Service, and it is one of the three Core components of the IB Diploma, alongside Theory of Knowledge and the Extended Essay. Rather than teaching content, CAS asks learners to grow through experience and structured reflection. Every Diploma learner completes it as a requirement of the IB Diploma Programme.

Creativity covers the arts and original, imaginative thinking.
Activity covers physical effort and healthy challenge.
Service covers genuine, sustained community engagement.

Breaking Down the Three Strands

Each strand of CAS develops something distinct, and together they build a rounded, reflective learner. A strong CAS profile balances all three rather than leaning on one. Here is what each involves.

Creativity

Creativity spans the arts, design, and any project that asks a learner to imagine and make something new. Producing an original piece of work, from music to a community campaign, counts here. The emphasis is on genuine creative effort, not polish alone.

Activity

Activity covers physical exertion and the discipline of sustained effort, from sport to dance to outdoor pursuits. The value lies in commitment over time, not one intense burst. Healthy challenge and perseverance are the point.

Service

Service asks for authentic community engagement, where a learner responds to a real need with others. Meaningful, ongoing involvement matters far more than a single day of volunteering. Reflection keeps the focus on honest intent.

How CAS Is Assessed Without Being Graded

CAS carries no marks and no points toward the 45-point total, yet it is a firm requirement for the Diploma. Learners build a portfolio of experiences and reflections, showing growth against a set of learning outcomes rather than a score. Honest, thoughtful reflection is what completing CAS actually demands, which ties it closely to the IB's emphasis on integrity.

Real CAS Projects at JBCN

CAS comes alive through real projects, and JBCN Learners take part in initiatives that span all three strands. The examples below, drawn from the school's CAS programme, show the range in practice.

Service partnerships such as the BMC School Bhoiwada initiative and collaborations with the Cuddles Foundation and Jai Vakeel.
Community and welfare projects, including a stray-dog welfare project and the DJED Foundation partnership.
Wider experiences like the Climate Action School project, CAS Edutours, and the CAS Exhibition.

Tips for Choosing Strong CAS Activities

The strongest CAS profiles come from genuine interest, not resume-building, so the choice matters. Sustained, reflective involvement always reads better than a scattered list. A few principles help.

Choose activities a learner genuinely cares about.
Favour sustained engagement over one-off events.
Build in honest reflection at each stage, not just at the end.
