Youth violence, both in and out of school, is a worldwide problem. Students' violence is manifested in form of bullying among students, physical fights, gender violence, and violence against school property during school strikes. Violence in secondary schools wastes a lot of learning time as students and teachers spend a lot of time dealing with disciplinary issues related to violence, at times it has also led to loss of life and school property in school fires during school strikes. The aim of this study was to examine the contribution of parenting styles towards students' violence in schools, in Embu county. Survey research design was adopted for the study.
