Introduction. The interest of the scientific community in the issue of ontogeny of subjectivity in the era of changes in all spheres of life, the reform of national education associated with the digitalization of education and other challenges is growing again. The problem of psychological support for the formation of subjectivity during the period of study at school is of particular relevance. It is subjectivity that is an integrative characteristic of a student's personality associated with transformative activity and the achievement of one's own goals. Subjectivity determines how a person interacts with the surrounding world and people, how he defends his position in interaction with people and society as a whole. The personal and professional choice of a student is associated with the ability to understand and model possible alternatives to his life path and to be responsible for the results. In primary school age, there are personal prerequisites for the development of subjectivity. The components of subjectivity in the structure of a student's personality are his features, such as the presence of an educational and professional motive, a motive for achievement and development, responsibility for one's actions and decisions, the ability to control oneself in a variety of situations, including difficult life situations, and an active behavioral position. School education, which includes not only the pedagogical influence on the student, but also his subjective educational activity, involving his active participation in building his own personality, is precisely the space that bears a great semantic and functional load from the point of view of the formation and development of intrapersonal mechanisms and formations. The creation of "correct", creative conditions for the education and development of a child in the process of schooling is a significant moment in the work on the formation of his subjectivity, including in relation to the choice of a professional path. The work on the formation of the subjectivity of schoolchildren in the field of modern general education is becoming an important and responsible task from the point of view of the development of a full-fledged personality and the future professional self-determination of school graduates.Materials and Methods. The article is an analytical review with elements of a pact research, where an attempt was made to systematize scientific psychological and pedagogical knowledge on the problem of the formation of subjectivity during the period of schooling. To study this personal characteristic, we conducted a theoretical and empirical study. The formation of subjectivity is due to the development of self-awareness and the motivational-semantic sphere of the individual. The most important, from our point of view, are such criteria for the development of subjectivity in a student as motivational indicators, the ability to reflect, the nature of interaction with adults, and the level of self-regulation. In accordance with the criterion-level approach, we identified three levels of development of the subjectivity of schoolchildren: low, medium and high.Results. All selected and studied by us criteria of subjectivity of primary and secondary schoolchildren are in the stage of active formation. That is why this study is of a trial, pilot nature. The data we have obtained demonstrate only the existing trend in relation to the personal development of children at certain stages of schooling. That is why the above mentioned criteria for the development of the subjectivity of schoolchildren need further study, and their typology needs additional refinement.Discussions and Conclusions. The conclusion is substantiated that the above mentioned criteria for the development of the subjectivity of schoolchildren need further study, and their typology needs additional refinement, which is a promising direction for further theoretical and empirical research. The work on the formation of the subjectivity of schoolchildren in the field of modern general education is becoming an important and responsible task from the point of view of the development of a full-fledged personality and the future professional self-determination of school graduates. Based on the results of the study, we consider it necessary to create meaningful and systemic conditions conducive to the development of the child's ability to subjective activity, awareness of himself and his life. The conditions are listed, that allow the development of the child's internal potential as a subject of his own activity in various aspects, not only educational, but also extracurricular, conducive to creative activity and self-development.
