School exclusion and violence are defined with boys as the reference point and relatively little attention is given to the various forms of exclusion--disciplinary exclusion, self-exclusion and withdrawal from learning--to which girls are subject. Girls in difficulty at school receive less attention than their male peers from policy-makers, teachers and researchers. They find it more difficult to access resources. The concept of exclusion needs to be expanded to encompass girls' experiences. This paper explores the policy context in which girls' exclusion occurs and examines contributory factors, arguing that together they constitute systemic violence. Forms of violence include verbal abuse, psychological violence and the everyday "incivilities" which often go unchallenged in school cultures. The paper draws on research which privileged student voices and considered them alongside those of service providers, to analyse girls' school experiences, examining violence and exclusion at interpersonal, institutional and structural levels. Issues such as bullying, self-exclusion, learning difficulties, peer relationships, teacher-student relationships and student pregnancies are considered. (Contains 7 notes.)
