IB Curriculum & Diploma Requirements
Students study six subjects selected from the subject groups. Normally three subjects are studied at higher level (courses representing 240 teaching hours, the equivalent of two years of study), and the remaining three subjects are studied at standard level (courses representing 150 teaching hours, the equivalent of one year of study).
Made up of the three required components, the DP core aims to broaden students’ educational experience and challenge them to apply their knowledge and skills.
The three core elements are:
Theory of Knowledge, in which students reflect on the nature of knowledge and on how we know what we claim to know.
The Extended Essay, which is an independent, self-directed piece of research, finishing with a 4,000-word paper.
Creativity, Activity, Service in which students complete a project related to those three concepts.
The six subject groups are:
There are different courses within each subject group.

Extended Essay
The Extended Essay is an in-depth study of a focused topic chosen from the list of approved Diploma Programme subjects— normally one of the student’s six chosen subjects for the IB Diploma. It is intended to promote high-level research and writing skills, intellectual discovery and creativity. It provides students with an opportunity to engage in personal research in a topic of their choice, under the guidance of a subject-area mentor (usually a teacher in the school) and a writing mentor. The extended essay has a prescribed limit of 4,000 words.
Theory of Knowledge
TOK is a thoughtful and purposeful inquiry into different ways of knowing and into different types of knowledge. As a result, the course is composed almost entirely of questions to be critically considered, rather than specific factual information. The central question is "What level of certainty, if any, can I assign to a given assertion of knowledge?” The course will be broken into four main categories: Knowers and Knowing, Ways of Knowing, Areas of Knowledge, and Linking Questions.
Creativity, Action, Service
Participation in the school’s CAS programme encourages students to be involved in artistic pursuits, sports, and community service work, thus fostering students’ awareness and appreciation of life outside the academic arena. Students are required to complete 150 hours of CAS beginning the summer prior to their junior year.
