The article is devoted to the problem of features of professional self-actualization of students-psychologists living in crisis of professional readiness. The definition of the term self-actualization and professional self-actualization among the works of domestic, Russian and foreign scientists is considered. In particular, professional self-actualization is defined as a complex multilevel phenomenon, a process of directed activity aimed at progress in one's own professional development, which is conditioned by the disclosure of one's own professional potential. Three approaches to the study of self-actualization in the professional sphere are highlighted: subject-activity, where professional activity is the main basis for self-actualization of the individual, due to difficulties and internal contradictions; personal development, where professional self-actualization leads to profound internal changes and forms and professional maturity; acmeological, in which professional self-actualization is the achievement of the highest level of professionalism, professional and personal maturity ("acme"). The concept of crisis of professional readiness and features of living of crisis by psychology students are analyzed. It is noted that the level of experiences of the crisis of professional readiness is the most intense among other normative crises of professional training. The peculiarities of the crisis development are highlighted: the contradiction between the awareness of the beginning of professional activity and at the same time the lack of readiness. The intra-personal conflict between learning motivations and professional motivation is determined. A number of features of professional self-actualization of students-psychologists and their interrelation with the crisis of professional readiness are considered.
