Abstract: The subject of the study is the relationship between child–parent relations and the effectiveness of adaptation of first-graders.The purpose of the study is to determine the level of adaptation to learning among first-graders brought up in families with different types of child-parent relationships. The importance for a child of child-parent relations in a difficult period for him at the beginning of school education is emphasized by many authors. Often, the reason for difficulties in adapting to school lies in the lack of formation of personal forms of communication between a younger student and his parents, in the inability of parents to build communication with a child according to the type of "child – adult as equal", in the habit of a parent to communicate with an already grown-up child according to the stereotype formed in preschool childhood. The study was conducted on the basis of the municipal autonomous educational institution "Secondary School No. 19 named after A.V. Sedelnikov" of the city of Krasnoyarsk. 30 parents (mothers of first-graders) and 30 children aged 7 years were diagnosed. There is a direct relationship between child-parent relations and the adaptation of first-graders to school. Students who are brought up in families with a democratic type of upbringing are characterized by successful, full adaptation. Schoolchildren from families in which permissive and authoritarian parenting styles are the predominant types of child-parent relationships, incomplete adaptation and maladaptation prevail. The conducted research makes it possible to develop psychological programs to increase the level of adaptation of first-graders to education for parents with an authoritarian parenting style and for parents with a permissive parenting style.
