International Baccalaureate

In 2002 King William's College began teaching the International Baccalaureate Diploma for the first time. Since then more than 900 students have studied the Diploma with us and we have become one of the largest and most successful IB schools in the British Isles. We believe that it is an excellent preparation for both university and life beyond and it is the only qualification we offer in the Sixth Form.


The IB Diploma Programme is a balanced programme of education that combines both breadth and depth of study. It places a strong emphasis on critical thinking skills and promotes a sense of international-mindedness. The programme is taught over two years and is recognised by all UK universities and by most leading universities around the world.


Students study six subjects, normally three at higher level (HL) and three at standard level (SL). They choose one subject from each of Groups 1 to 5, which includes languages, the humanities, science and mathematics. The sixth subject may be an arts subject chosen from Group 6 or another subject from Groups 1 to 5.

In addition, the programme has three core requirements that are included to broaden the educational experience and challenge students to apply their knowledge and understanding:

Because there are nine components in all, IB students learn how to organise themselves, think independently and take responsibility for their own learning. These are invaluable skills that will allow the students to go on and succeed at university.

We find that IB students adapt more easily to university style of education and become independent learners from an earlier stage compared to those from other backgrounds. Dr Lorraine Craig, Imperial College, London

Faced with the difficult choice of our daughters remaining at a perfectly good state school in the Isle of Man, we chose to send them to King William’s College to study the International Baccalaureate. The outcome in both cases was a resounding endorsement of our decision, since King William’s College operates and delivers at a different level.
