IB core: TOK, CAS, EE

Theory of Knowledge || Creativity, Action, Service || Extended Essay

taking on the challenge of IB Diploma

At the heart of the IB Diploma Programme are three core requirements that help students grow as thinkers, researchers, and compassionate community members. Through Theory of Knowledge (TOK), students examine how knowledge is constructed across disciplines; through the Extended Essay (EE), they conduct independent, college-level research on a topic of their choice; and through Creativity, Activity, Service (CAS), they engage in meaningful experiences that build well-rounded, reflective, and community-minded learners. Together, these core elements deepen understanding, strengthen skills, and embody the values of the IB Learner Profile.

Theory of Knowledge (TOK)

TOK asks students to explore how we know what we know. Through discussion and reflection, they examine different perspectives, question assumptions, and develop strong critical-thinking skills. Click here for the TOK course description.

Extended Essay (EE)

The Extended Essay is a student-driven research project on a topic of personal interest. Students learn to investigate, analyze, and write at a college level, producing a 4,000-word academic paper.

Creativity, Activity, Service (CAS)

CAS encourages students to grow beyond the classroom through creative expression, physical activity, and community service. These experiences help students develop balance, empathy, and a deeper connection to their community. Click here for the most recent CAS Handbook.
