The present project united the schools of 5 European countries, which developed the mediation system at schools for the purpose of students' support in the educational process. School mediation supports those students who are at risk of dropping out from school due to conflicts, their cultural background, disadvantaged positions, etc. The pilot program for mediators was launched in Estonia and then the efforts and experience of different countries were combined for the primary purpose of the new project: create a free systematic methodical resource book (a model ) for motivation, training and practical work of school mediators, based on the experience of European countries, as well as the subsequent implementation of the model of mediation in the European Union as an alternative method of conflict solving in the educational institutions. The model and materials of the resource group were tested in all partner institutions: Narva Kesklinna Gümnaasium (Estonia), Escola Secundária Dr. Joaquim Gomes Ferreira Alves, Valadares, Vila Nova de Gaia (Portugal), Gimnazija Brezice (Slovenia), Bundesgymnasium und Realgymnasium Wien 21 (Austria), Kozgazdasagi Politechnikum Alternativ Gimnazium es Szakkozepiskola (Hungary).The participants were 3-4 adult specialists (teachers, management, social workers) and 10-12 students from each country who prepared meetings, actively implemented the project program in the schools, worked out materials, analyzed mistakes and best practices, organised seminars. Apart from the local work the project included 2 transnational partner meetings and 3 international short-term training activities. Indirect project participants were children from Form 2 to 7, their class teachers, who were interested in promoting mediation system, were in contact with their parents, received assistance in creating friendly classroom atmosphere, assistance in solving quarrels, and the parents of these children, who were notified and gave their agreement for their children's interaction with the mediators.The main result of the project is the logical culmination of the primary purpose - the creation of a manual (a model) for professionals on the preparation of school mediators and subsequent dissemination and implementation of the model n the EU.
