You can also support the IB

I can support the IB work with making IB programmes available in developing countries and to financially-disadvantaged students. If you find time and you have experience to offer, then read our information for volunteers to find out how volunteers make a big change to our work.

IB schools are different: the teachers share all their knowledge and experience with the students whatever the question is, plus these teachers are committed to the professional development of their knowledge.
