The IB Diploma Programme is an academically challenging and balanced programme of education with final examinations that prepares students, normally aged 16-18, for success in university and life beyond. The programme is taught over two years and has gained recognition and respect from the world's leading universities, often leading to preferential admissions and earned college credits for IB students.

The programme encompasses an in-depth study of six major subjects; three subjects are studied at Higher Level and three at Standard Level, allowing students to pursue advanced work in subjects of particular interest.

Three additional academic specializations outside the classroom are also part of the programme:

Theory of Knowledge, is a critical thinking course which trains students to think about knowledge and its origins at the deepest of levels.

The Extended Essay engages students in independent research on a topic of their choosing, providing them with the opportunity to explore a subject further and to create a mature piece of extended writing.

Creativity, Action, Service. Known by its acronym CAS, Creativity, Action, Service (CAS) balances academics with hands-on learning outside of class. 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.

At the end of Grade 12, IB Diploma candidates complete oral and written examinations in all of their IB subjects. IB exams are prepared and externally graded under the supervision of the International Baccalaureate in Geneva.
