In Sweden, school staff are legally responsible to report concern for a child’s welfare to social services. This obligation can be regarded as a cornerstone of social protection for children exposed to various forms of domestic violence, including honour-based violence (HBV). However, research indicates a tendency to underreport suspicion of child neglect by occupational groups in countries that apply mandatory reporting laws. This article examines the questions: How do school staff reason on their legal responsibilities in relation to reporting children and young people with a migrant background who are exposed to, or suspected victims of, HBV? What specific dilemmas can be identified in such situations? The study is based on qualitative interviews with school staff, particularly school counsellors, and a qualitative thematic analysis has been conducted. The results indicate that HBV is a complex field for professionals to handle and often becomes a subject of negotiation in relation to mandatory reporting. School staff commonly express a lack of trust in the social services’ knowledge or possibility to support children or young people in honour-based contexts. The respondents also reason around the notion that a report might lead to a worsened situation for the young person and increased control from the family. This all together shows an uncertainty or an internal moral conflict on the reporting obligation among school staff. © 2023 The Author(s).
