The Core of the Diploma Programme aims to broaden students' educational experiences and challenges them to apply their knowledge and skills. The core consists of three required components: Theory of Knowledge, Extended Essay, and Creativity, Activity, & Service.
Theory of knowledge (TOK) is assessed through an oral presentation and a 1,600 word essay. It asks students to reflect on the nature of knowledge, and on how we know what we claim to know.
Creativity, activity, service (CAS) is one of the three essential elements that every student must complete as part of the Diploma Programme (DP).
