School developments are often not effective. Many innovations and developments like a new way of teaching a specific subject are initiated in schools, but they often lack scientific information or research evidence for a deeper analysis of the questions behind the problem or solutions. In other words schools develop policy or innovations without knowledge utilisation from science or research.  A Dutch partnership of primary schools and researchers including Prof. Marjan Vermeulen researchers in the Welten Institute of the Open University of the Netherlands have been examining this challenge and  set themselves the task of developing a sustainable and evidence-informed framework to support school development.
