Introduction. The issue of bringing up youth in the era of both upbringing and family crises implies the necessity of discovering new possibilities for exerting the influence on the development of the young generation. In the article the hidden form of developing young persons is put forward, and is simultaneously available for being applied especially during the foreign language classes. Aim. The aim of this article consists in outlining the possibilities arising from foreign language teaching in the light of evolving the social competencies of young people, as well as their moral and spiritual competencies, which have not been hitherto highlighted in the Polish foreign language didactics. This aim is ultimately directed at providing the support for parents in raising the younger generation. Methods. The following methods have been made use of as part of this work: the analysis of the subject literature, the method of logical reasoning and the heuristic method. Results. The skilful selection of methods and forms of work with students as well as that of the teaching materials contributes to educational formation of the youth. The extent to which the lessons may provide help to adolescents and, at the same time, to their families, is also made conditional upon ingenuity, openness, creativity, engagement and the potential of the teacher himself. In the course of preparation of the lessons, not only should every teacher ponder the way of imparting the knowledge, but also about choosing such activities that could additionally develop the social skills and the moral and spiritual values of students. The performance of an educational function cannot be reflected by a pure fiction after all, as it is a special task through which the teacher may substantially support another social cell, i.e., the family being so deeply in need of help nowadays.
