 IBDP World School Logo

The International Baccalaureate (IB) Diploma Programme is a rigorous two-year curriculum widely recognized by the world’s leading universities and offered at Year 5 (Grade  11) for students aged 16-19 years. 

Components of IB assessment include: 

Extended essay (EE)

The EE has a prescribed limit of 4,000 words. It offers the opportunity to investigate a topic of individual interest in one of the student’s DP subjects, and equips students with independent research and writing skills expected at university.

Theory of knowledge (TOK)

The interdisciplinary TOK course is designed to provide coherence by exploring the nature of knowledge across academic disciplines, encouraging critical thinking and an appreciation of divergent human perspectives.

Creativity, Activity, Service (CAS)

Participation in CAS activities encourages students to be involved in the arts, sports and community service work, fostering students’ personal and interpersonal development outside the academic arena.

The Six Subject Groups

Students study six subjects selected from various IB subject groups. At least three subjects should be studied at Higher level (each subject involving 240 teaching hours), and the remaining three subjects studied at Standard level (each subject involving 150 teaching hours).

Failure to meet CAS requirements or an ‘E’ grade in either TOK or EE can result in students not being awarded the Diploma. (Please refer to  ibo website for additional requirements). This gives a final maximum mark of 45. A Diploma is awarded upon attaining 24 points and meeting all IB requirements.

Universities will give conditional offers requiring a specific number of points. The offers will depend upon the standing of the university and the popularity of the subject.
