Abstract: The article presents the results of the study of the professional identity of graduate students in psychology. Using the method of expert assessments and subsequent application of mathematical and statistical procedures, 'real self' and 'ideal self' images of professional identity of psychology students are revealed. Significant characteristics of the image of a professional psychologist are determined, which is correlated with the expectations and representations of students. The process of self-identification of students with the image of a psychologist (consultant and educational psychologist) as well as the specifics of the formation of the 'Self-concept' of a young specialist is considered.

Sullivan); theory of semantic differential (by C. Osgood); systems approach to the study of the professional 'self-concept' (by S. D. Janerian). The methods of research involved methods for collecting diagnostic information such as the method of interpersonal diagnostics developed by T. Leary, G. Leforge, R. Sazek, the method of the semantic differential by C. Osgood, and the method of expert assessments. Methods of mathematical and statistical analysis of the data included the method of expert assessments, Student's test, factor analysis, correlation analysis, and SPSS 22.0 software. The novelty of the research is caused by the fact that the author choose methods for constructing the professional identity of psychology students, compare the image of an educaitonal psychologist with the expectations and representations of students, and use methods of mathematical and statistical data processing. The main conclusions of the study are the types of perception by students of the images of professional psychologists in the field of teaching and counseling.
