[The role of the school system in the prevention of terrorism].

Schools are a place within which teenagers' anxieties are expressed, as well as those of adults, in the difficult confrontation with otherness, in a context of conflictual globalisation. The school is a key player in the prevention of terrorism, through the elaboration of these tensions which it can allow. The Métisco team offers school mediation programs, in order to help professionals fulfil this mission.
