Cooperation between parents of children with this disorder and the government city of the city of Wrocław, resulted in the creation of integration departments with homogeneous disability in 2009. Commonly, various disabilities still prevail in integration groups. The aim: The purpose of the article is to answer the question: why is peer tutoring so important for the development of children? Method: Participatory observation. Results: Peer tutoring provides a sense of security that mainly depends on the relationship between peers. Teachers are mainly responsible for organizing situations conducive to developing sensitivity to the needs of a peer, children who may need help in various areas of their development. At the same time, such a teacher should pay attention that none of people is self-sufficient and that everyone has some gaps in knowledge or skills that require the support of another person.
