NCDO has examined the opinions and methods of teachers and directors with regard to global citizenship, as well as the obstacles and opportunities they experience around global citizenship in education. More than 1,500 teachers and almost 300 directors have participated in the research. A large majority of the teachers in primary and secondary education think that global citizenship is an important subject for Dutch education. Also, the majority of the teachers are of the opinion that it is important that the lessons link up with current events. Nevertheless, only a minority of the teachers in primary and secondary education believe that global citizenship should be a compulsory part of the curriculum. It is mainly teachers of geography, economics, cultural and social subjects who are of the opinion that global citizenship is an important theme.
