Violence is a major preoccupation in the school milieu and it is known to take different forms. Some forms, such as intimidation, bullying and physical aggression cause a great deal of worry and indignation. Other more subtle forms, such as put downs, contempt and rejection are more likely to go unnoticed. Moreover, little is known about the profiles of students who are victims and perpetrators of this violence. This article tries to shed more light on this subject, based on the results of a study done with 784 students in grades four to six, in six Québec City elementary schools. Apart from the relative importance of the different forms of violence, the data collected shows that boys, older students, and those who agree with the idea that violence is an acceptable behaviour, are among the students who adopt more violent behaviour. Boys and students who agree that violence is acceptable behaviour are also more often victimized. Students were grouped into four categories (peaceful, victims, intimidators and turbulent) to better define the characteristics of each type of student.
