In the International Baccalaureate (IB) Diploma, CAS stands for Creativity, Activity, Service and is one of the three core components of the IB Diploma Programme. It is a structured program that requires students to engage in creative, physical, and community-service activities outside the classroom over two years. CAS is not an exam in the traditional sense, but the IB Diploma is not awarded without successful completion of this component.
The following sections answer the most important questions about requirements, reflection, and assessment.
Which Activities Count as CAS in the IB Diploma?
In the IB Diploma, all activities that can be assigned to one of three strands count as CAS:
- Creativity: Creative pursuits such as drama, music, art, or design
- Activity: Physical activities such as sports, dance, or outdoor projects
- Service: Volunteer engagement for the benefit of other people or the community
What matters is that the activities are new or represent an intensification compared with the student’s previous routine.
Concrete examples of recognized CAS activities include:
- Founding or leading a school band or drama group (Creativity)
- Joining a sports team or training regularly in a new sport (Activity)
- Volunteering at a local nursing home or food bank (Service)
- Organizing a charitable project such as a fundraiser or an environmental project (Service)
- Taking part in a creative workshop or a design project (Creativity)
What Is the CAS Project?
The so-called CAS project is particularly important. Every student must carry out at least one collaborative project that covers at least two of the three CAS strands and is planned, implemented, and reflected on over an extended period. The project strengthens teamwork, initiative, and a sense of responsibility.
How Many CAS Hours Are Required in the IB?
The IB does not set a fixed minimum number of CAS hours. Instead of counting hours, the IB assesses the process, the reflection, and the achievement of the seven learning outcomes over the entire period of about 18 months to two years. As a guideline, however, many IB schools recommend at least 150 hours, divided among all three strands.
What counts is not the number of hours alone but the quality and variety of the experiences. Students should make sure that all three strands are evenly represented and that they remain continuously active throughout the IB program. A sudden flurry of activity shortly before graduation is generally not accepted by the IB coordinator, since CAS is based on sustained engagement.
What Are the Seven CAS Learning Outcomes and Why Are They Assessed?
The IB’s seven CAS learning outcomes describe the competencies and experiences that students should demonstrate through their engagement. They are assessed because the IB wants to ensure that CAS brings about real personal growth and is not just a checklist of completed activities. All seven learning outcomes must be demonstrated at least once over the course of the program.
The seven learning outcomes are:
- Identify strengths and areas for development (recognizing one’s own abilities and limits)
- Take on challenges and develop new skills
- Initiate and carry out a plan (initiative and organization)
- Show perseverance and commitment
- Work collaboratively (teamwork and learning together)
- Recognize global significance (making connections to social or global issues)
- Consider the ethical implications of actions
These learning outcomes are not graded, but they must be evident in the documentation and reflections. An IB coordinator checks whether the activities and the accompanying reflections credibly demonstrate the learning outcomes.
How Does CAS Reflection Work and What Needs to Be Documented?
CAS reflection is the core element of the documentation and must show how students have learned from their experiences. The individual activities, the accompanying reflections, and evidence (e.g., photos, reports, certificates) must be documented. Reflections can be written or submitted as video, audio, or a blog.
Good reflections answer concrete questions:
- What did I do?
- What did I learn from it?
- What challenges arose and how did I overcome them?
- How does the activity relate to the CAS learning outcomes?
Superficial descriptions are not enough. The IB expects an honest, critical examination of one’s own experience.
Where Is CAS Documented?
Documentation usually takes place on a digital platform such as ManageBac or a comparable system provided by the school. Regular meetings with the CAS supervisor, who oversees and confirms the activities, are also part of the process.
What Happens if CAS Requirements Are Not Met?
If the CAS requirements in the IB Diploma are not met, the diploma is not awarded, regardless of how good the exam results in the other subjects are. CAS is a required component of the IB Diploma Programme, and the IB treats it just as seriously as the written exams.
Common reasons for not meeting the CAS requirements include:
- Incomplete or missing reflections
- Activities that do not cover all three strands
- A missing CAS project
- Not all seven learning outcomes were demonstrated
- Engagement that starts too late or is irregular
Schools therefore usually use interim checks and regular meetings with the CAS advisor to make sure students stay on track. Those who plan early and stay continuously engaged have no difficulty meeting the requirements.
How Does CAS Differ From Other IB Core Components Such as TOK and the Extended Essay?
CAS differs from Theory of Knowledge (TOK) and the Extended Essay (EE) in that it is not a written exam or a graded piece of work. While TOK calls for a critical examination of knowledge and epistemology and the Extended Essay requires an independent research paper of about 4,000 words, CAS focuses on active, experience-based learning outside the classroom.
What Is TOK and How Is It Graded?
Theory of Knowledge is a philosophically oriented course that leads students to question the foundations of knowledge. There is a TOK essay and a TOK presentation, both of which are graded and count toward the overall diploma score. CAS, on the other hand, is not graded but simply rated as completed or not completed.
What Is the Extended Essay?
The Extended Essay is an independent research paper on a freely chosen topic from one of the IB subjects. It fosters academic writing skills and scholarly thinking and is also graded. CAS pursues a different goal: it is about personal development, social engagement, and physical activity, not academic performance.
Together, all three core components, CAS, TOK, and the Extended Essay, form the so-called IB Core and are jointly required to receive the IB Diploma. They complement one another: TOK trains thinking, the Extended Essay trains research, and CAS trains action.
How Does ISR International School on the Rhine Support Students With CAS in the IB?
We know that CAS can seem complex to many students at first. That is why we guide every IB student at ISR International School on the Rhine in Neuss, near Düsseldorf, Germany, through the entire CAS process in a structured way from the very beginning, from choosing suitable activities to the final documentation.
- Our experienced CAS supervisors support students individually and help with planning, reflecting on, and documenting their activities.
- Through our CAS projects at ISR, we offer concrete opportunities to find and carry out meaningful, recognized activities right within the school environment.
- We make sure that all three CAS strands are covered and all seven learning outcomes are demonstrated before the diploma is applied for.
- Regular check-ins and clear deadlines help students keep track and stay on course in good time.
- Our three full-time University & Career Counselors also help students make meaningful use of their CAS experiences in applications to universities worldwide.
Over the past three years, 100% of students who pursued the IB Diploma completed it successfully and thereby obtained the German general university entrance qualification (Allgemeine Hochschulreife). Would you like to learn more about our IB program? We warmly invite you to attend one of the ISR Info Days and see our school community for yourself.
