External support by a local coordinating agency facilitates the work of school-to-school networks. This study provides an innovative theoretical framework to analyse how support provided by local education offices for school-to-school networks is perceived by the participating teachers. Based on a quantitative survey and qualitative interview data from a networking project in eight German districts, we argue that in order to enable networks to work independently on innovative reforms, local coordinating agencies should focus on autonomy support, such as training on network management, and on support aimed at establishing significance, i.e. through vision and goal setting.
