As far as we have been able to ascertain, there are no schools offering both the CBSE curriculum and the IB programme. The norm is for schools to offer the IB programmes at different stages in the school curriculum – so some international schools offer a mixture of IB Primary Years and Middle Years programmes, but then add the IGCSE during grades 9 and 10 in order to enable students to sit public exams, prior to offering the Diploma programme for grades 11 and 12. Similarly, a growing number of UK curriculum schools have replaced their traditional A Level programme with the IB Diploma, but it seems that Indian curriculum schools are not inclined to mix curricula in this way.
