The research is aimed at studying the professional and personal self-development of future pedagogue-psychologists. In the article, the authors describe in detail and analyze the essence of the concept of professional self-development. The structural components of the process of professional self-development of pedagogue-psychologist, such as motivational-target, content-operational and reflexive, are presented, analyzed, and the corresponding criteria of the process of professional self-development are determined for them. The method of professional development "portfolio" is considered as a set of materials demonstrating the ability of students to solve problems of professional activity, choose a strategy and tactics of professional behavior and designed to assess the level of professionalism. The authors present the developed elective course "Pedagogical Acmeology", which contributed to arming future pedagogue-psychologists with theory and technologies that provide the possibility of successful professional and personal self-realization. Classes within the framework of the elective course were held in the form of lectures, seminars, discussion of reports on the problems of pedagogical reflection, conducting acmeological training sessions. A summary of the experimental study is presented, where reflective attitudes to the system of one's actions, the ability to create personal portfolios of professional, personal self-development and the further development of reflective abilities were observed.
