Beginning in 1988 and currently with 20 schools working together with the University of Amsterdam, the network focuses on the restructuring of upper secondary education in the Netherlands aimed at more active learning process and democratic education. The network develops new initiatives in schools and attempts to influence educational policy and is distinguished by the following functions: interpretation of government policies; influencing government policies; learning from other's experiences; using each other's expertise; developing new educational approaches and materials; and creating new initiatives. In particular the interaction between changing school practice and influencing educational policy will be discussed by looking at the balance between bottom-up and top-down processes and at the different types of citizenship one wants to realize. The chapter focuses on successes and obstacles of networking. It demonstrates how teachers and school leaders along with university faculty and students build together communities of learners and develop as a network an educational vision that connects schools in the network.
