There is great potential in identifying struggling schools at an early stage and providing them with appropriate support. However, relevant knowledge, effective measures, and goal-oriented collaboration are still lacking. Therefore, the Robert Bosch Stiftung initiated the Community of Practice to Improve Support for Struggling Schools. Over time we expanded the network across national borders and finally, to an international network. Representatives from school administrations, school supervisory bodies, state institutions, and pilot projects as well as school leaders are actively participating in the community of practice. Currently, seven German federal states and the state of Austria are part of the community of practice.
