The paper presents the results and the analysis of the experimental study aimed at the identifying of the influence of personal self-perception on the professionally significant features of an individual for the representatives of the state service authorities. The study identified that the expressiveness level of certain self-perception modalities is closely interrelated with the significance for an individual of a certain sphere of life and his or her commitment to the certain terminal values. The detailed analysis of the studies of self-perception showed that self-perception as a motivational-conceptual formation determines the area of “significant” in self-sphere. Self-consciousness determines the direction bonded with the self-actualization formation. It is determined that, in general, the participants of the study are concerned with their self, love for yourself, feel the value of own personality and the virtual value of own personality for other people. At the same time, they percept themselves as fully independent, forceful, active and reliable people, which have the reasons to respect themselves and for which it is typical to have a higher self-esteem, confidence, and the lack of internal tension. However, more than the third part of the sample does not have the sufficient level of self-reflectiveness that proves the inability to estimate oneself critically, to realize one’s actual pros and cons. A considerable number of participants is ready to put the blame for their failures on other people. In general, it is possible to speak about the fact that the most part of the research participants is capable of deep self-insight, the formation of adequate self-image, the consciousness of one’s difficulties, and thus of self-development.
