Dr Siva Kumari, Director General, the International Baccalaureate, has written the foreword to a new John Catt title, ​Whose History? – Essays in Perception, edited by Dr Caroline Ellwood.

This year marks the 25th anniversary for 11 International Baccalaureate (IB) World Schools in the Africa, Europe, and Middle East region that have offered the IB Diploma Programme (DP) for a total of 275 teaching years between them. They join many more schools worldwide that have passed this milestone anniversary.

What makes it different and what makes it special? The IB has more than one million students enrolled across 145 countries. We take a look at the IB's mission statement, learner profile and programmes.
