The aim: Early school education involves the family in the process of institutional education of children, in achieving common goals. In the minds of representatives of both environments, joint actions should serve the good of the child, its multilateral development, and meet the needs of school adaptation. The preparation of the child for the role of a student is already beginning at home. A family in which a child is brought up is undoubtedly the most important factor in his preparation for a new environment. When this preparation is carried out correctly, it significantly determines the use by the student starting institutional education of its development opportunities to reach the full potential. The experiences of the first days are the beginning of a difficult and complex process of adapting to the new environment. It is very important that the child as a student feels as comfortable as possible from the beginning. Method: Analysis of the literature. Results: The processes of school adaptation of a child starting school is optimized by the cooperation of parents and teachers. It results in: an increase in the propensity to help others, the development of trust and the recognition of similarities between group members in terms of intentions, values and attitudes. The climate of kindness and understanding created jointly by cooperating adults favours the child – the student – developing attitudes aimed at exploring the new environment, satisfying cognitive and social needs, and not focusing on defending against the unknown and incomprehensible.
