The present study examines how a number of Swedish schools define and categorize students who have been exposed to different forms of violent or abusive acts in school. The study will shed light on how categorizations and forms of explanation used in the schools by professionals emerge from central institutional and professional discourses. The data are gathered from interviews with key officials and observations from school health team meetings. The results indicate a tendency toward more and detailed legal regulations concerning how schools act and react in relation to violent behavior.
