Abstract
The year 2007 was a significant one for the International Baccalaureate (IB) in England and Wales. Several milestones were reached, and the number of schools offering the curriculum reached one hundred. This article charts the growth and development in England and Wales of this continuum of international education and shows how the Diploma Programme, in particular, has reached a fundamental crossroads. On the one hand, the IB looks set for further growth and has the ability to be an influential and respected catalyst for the movement towards international education in curriculum development. On the other hand, the IB is emerging as an elite programme of study alongside other ‘baccalaureate’ curricula and in competition to A level, and other ‘Diploma’ developments. The ability of the IB to be a divisive force is explored.
