How to prevent terrorist acts has become a key question within current policy debates. In search of relevant actors that can contribute to the prevention of radicalisation, schools were identified to play a major role. The purpose of this policy brief is to state why and how prevention of radicalisation should be implemented in schools and to outline the status quo in Germany. Furthermore, the article gives policy recommendations. The content is mainly based on the approach of the German organisation ufuq.de, which works on the topics of Islam, anti-Muslim racism and the prevention of Islamism.
