he article discusses the provisions of research on the problems of models of professional self-determination. The approaches of scientists to understanding the essence of the concepts of "self-determination", "professional self-determination" are analyzed. The relevance of the topic is due to the fact that the system of professional training of future specialists is not sufficiently aimed at the formation of a specialist as a person and professional with a certain set of personal qualities, values, knowledge, abilities and skills. There is growing interest not only in the development of the theory and practice of social work, but also in the personality of a professional, his features and qualitative characteristics. This work is an attempt to generalize the existing models of professional self-determination and to reveal the specificity of the circumstances of such self-determination for the sphere of social work, as a separate case of self-determination, acquires specific features due to the conflict of individual features and ideas of the future social worker about himself, his role and status in the communities surrounding the individual , about society (formed by cultural norms) and individual factors that are characteristic of this field of activity. The article used such research methods as the method of theoretical analysis, modeling, abstraction. As an approach for analyzing the structure of the act of self-determination, we used the model proposed by P.G. Shchedrovitsky in works on positioning / self-determination / self-identification. The analysis of the phenomenon of professional self-determination through the prism of this model of the act of self-determination made it possible to single out the specifics of the main groups of factors relevant to the process of professional self-determination of a future social worker.
