The International Baccalaureate Diploma Programme (IBDP)

The IB Diploma Programme (IBDP) was established in 1968 and has earned a reputation as a broad, balanced, and rigorous curriculum for pre-university education. It is recognised and respected by the world’s leading universities. ISB offers more IBDP courses than any other school in Belgium, thereby providing students with more choice and flexibility to pursue the diploma programme that best suits their needs.
The IBDP is offered at ISB alongside the US High School Diploma, adhering to the minimum credit requirements.

The IBDP curriculum is suited to students who wish to maintain a broad base of subject specialisms. Students study 6 academic disciplines, three at Higher level (HL) and three at Standard level (SL). These must include two languages, mathematics, a science and an individuals and societies subject. The sixth subject can be an arts subject or a second subject from IB groups 2, 3 or 4.

Students also complete the DP core, which consists of Theory of Knowledge (TOK), Creativity, Activity and Service (CAS) and the Extended Essay (EE). Throughout the course there is an emphasis on developing thinking, researching, communicating, self management and social skills.

The IBDP is assessed externally by IB examiners and moderators, and in most subjects there are summative examinations in May of the second DP year which cover the material learned throughout the 2 year programme. Each subject is graded on a scale of 1 to 7. Assessment of the core courses can earn an extra 3 bonus points and so the maximum score possible is 45 points.
