The article considers the possibilities of preparing teenagers for family life through the use of active-forming technologies of social work. The crisis of the institution of the family, the loss of their functions by the family has attracted the attention of scientists for more than a decade. The crisis of the family is closely connected with the spread of negative processes in society as a whole. Among them: an increase in the number of teenage pregnancies, the incidence of HIV, a decrease in the birth rate, etc. This confirms the relevance of work in the field of sexual education of schoolchildren, the formation of a positive image of the family in society, and increasing the parental and marital competence of young people. Despite this, classes to prepare schoolchildren for family life in Russian educational institutions are still not held. The authors propose to use active-shaping technologies of social work for these purposes. The interactive nature of the proposed course has many advantages. It allows teenagers to be more open in discussing intimate topics, ask clarifying questions and express their own opinions during class. The article discusses the psychosocial characteristics of adolescents, presents the results of testing an active-forming program for preparing adolescents for family life in work with high school students.
