It is impossible to organize a well-founded process of personality development without pedagogical diagnostics aimed at studying the individual characteristics of pupils and the socio-psychological characteristics of the children's collective. With the help of diagnostic techniques, the teacher receives data on the state of the educational process, the quality of education and upbringing of students, processes this data, analyzes and evaluates them, corrects and predicts the development of the educational process and students. In the process, the younger generations must assimilate what has already been accumulated by society, that is, to assimilate educational knowledge, values brought to their level of development, master a certain culture of behavior, abilities, learn the norms and experience of society's behavior and develop a certain system of views on life. Upbringing is the process of transferring social and historical experience by the older generation to new generations in order to prepare them for life and work, which is necessary to ensure the further development of society. Today, modern society is moving towards the modernization of education. As a result of significant transformations, state educational and subject standards are aimed at teaching in their content, giving secondary importance to the education of students and value orientation. It is necessary to determine the level of upbringing with the help of diagnostic tools, methods and techniques and, based on the identified qualities, organize a student-oriented and personality-oriented upbringing process.
