Programs and technologies for the prevention of social risks in the education system are concidered from the standpoint of an evidence-based approach. The article presents the results of approbation and analysis of the «Skillful class»-method effectiveness. This is a Russian adaptation of the Finnish Skilful Class solution-oriented program, which implements a creative and positive approach to teaching children with emotional and behavioral difficulties in the class / group. It was based on the Kids' Skills method of Ben Furman, his 15-step-program for developing children social skills. The technology has been tested at more than 20 regions platforms. Statistically significant indicators of the formation and dynamics of skills mastered by children were termed as well as other parameters that are significant for reducing risk factors of the deviant behavior. This method can serve as a tool for early prevention of social risks that appear in preschool and primary school age (school maladaptation, emotional and behavioral problems, deviations, ostracism, school bullying, conflicts).
