The research "Role of students and teachers in school violence in public high schools in the State of Sonora" aims to characterize the different roles assumed by students and teachers in school violence. Focusing on describing attribution variables and continuous variables (which measure: levels of violence, roles, moral emotions, behavioral variables, socioeconomic variables and risk behaviors) that discriminate each one of the roles exercised in this type of situations and that were chosen for standing out as the most important secondary schools on this topic. Type of research, quantitative approach, survey method, probabilistic sample. A total of 2352 students and 395 teachers from 64 schools in the state of Sonora participated. The results indicate that each of the roles and their sub-levels adopt different levels, with those older than age and grade being the ones who mostly assume the role of aggressors. Likewise, the incidence of female aggressors has increased according to other comparative studies with this work, in a ratio of two male aggressors to one female.
