School is one of the most important socializing environments for children, since it is where they spend a great deal of time interacting with teachers and peers. However, the persistent spillover of community socioeconomic conditions and violence means that schools and their surroundings are no longer protected places, but share in the day-to-day violence of the urban space (Abramovay, 2002; Gottfredson, 2001). As a result, school violence has increased correspondingly.
