This work investigates teachers' perspectives on their responsibilities and conditions for conducting crime prevention work in Swedish schools located in socio-economically disadvantaged areas. Due to unclear guidelines regarding the teachers' role in crime prevention, the study focuses on how teachers perceive and approach these tasks. Using a qualitative research approach based on semi-structured interviews with five teachers, in three different school, the study explores the challenges and opportunities teachers face in this work. The collected empirical material was analyzed through thematic analysis and interpreted using relevant theories, such as Social band theory. The study's findings show that despite uncertainty about their defined responsibilities, teachers take an active role and see crime prevention work as an integral part of their professional role. The conclusions emphasize that teachers' ability to work crime-preventively is strongly influenced by challenges at both the individual and societal level, including high crime rates, limited future prospects, social traumas, and stigmatization. Furthermore, the study highlights that effective crime prevention strategies largely involve building strong relationships with students and creating motivation and meaningfulness in their studies to reduce the risk of deviant behaviors.
