Female genital mutilation (FGM) is a common traditional practice especially in some African countries and parts of Asia. However, due to high numbers of migration it is practised all over the world, also in Germany. Nevertheless, the common knowledge among the German society about the phenomena is low, even among professionals working with young girls. This lack of awareness causes many problems among society. In particular for girls that are looking for help. How should school social workers prevent the practice if they are not aware about it? School social workers have an important role since they are in close contact with the girls and should be able to react appropriately. FGM is a harmful and dangerous practice that violates human rights and comes with many long-term health effects for the girls and women. It is a global concern and should not be ignored. Through qualitative individual interviews this research shows what role school social workers in primary schools in Germany play to prevent the practice and if their knowledge is sufficient to provide adequate prevention.
