The international federation of researchers on violence in schools began in 1998, an initiative of the European Observatory on School Violence. Many international meetings were organized, and, in particular, the first world conference "Violence in school and public policies", in 2001, in Paris. This first conference notably widened the network of researchers, and the second world conference was co-organized by the Centre de Recherche et d’Intervention sur la Réussite Scolaire (CRIRES), in 2003- Quebec, when the Canadian Network of Schools Violence Prevention was created. The third world conference will take place in Bordeaux in January 2006 (papers from 35 countries had been proposed). The United Kingdom- more specifically, the University of Surrey- created the UK Observatory for the Promotion of Non-violence, and will co- organize the fourth world conference in 2007, before the conference of Ottawa in 2009. An international on-line journal will be created in the next few months. The volume of new research and publications is increasingly growing and the bonds among the network are becoming even stronger. Thus, this federation has reached a phase of maturity, surpassing the European territory. This is why it was decided to create an "International Observatory of Violence in the School Environment", a recognition of the establishment of a world structure.
