The article discusses issues related to the peculiarities of the professional choice of graduates of public education organizations. There are results of the study presented, which allow us to determine the role of conscious self-regulation of the activity of young people who find themselves in a situation of having to make a professional choice (on the example of students of a pedagogical university). The research involved 302 first-год students studying in the field of training 44.03.01 «Pedagogical Education». As research tools, the «Motivation of teaching pedagogical university students» methodology by S.А. Pakulina and M.V. Ovchinnikov and the questionnaire «Style of self-regulation of behaviour» by V.I. Morosanova were used. The data obtained during the research were organized, processed and interpreted using mathematical methods. It was found that first-год students who, upon entering the university, made a professional choice more consciously, taking into account their interests and inclinations have a well-developed need to think through their actions and behaviour to achieve their goals and their action plan is detailed. They are also characterized by independence in designing an action plan to achieve individual goals, flexibility in the situation of unforeseen circumstances, an advanced adequate assessment of themselves and the results they achieved. As the main conclusion, the following is formulated: the possession of a developed system of conscious self-regulation of arbitrary activity in an individual who is at the stage of choosing a profession allows him to make an adequate professional choice, which, in turn, is one of the conditions for the actualization of professional and personal potential.
