Drahomanov and 5th courses of the Faculty of Psychology named after T.G. Shevchenko and the Faculty of English of the National Linguistic University. From the analysis of the conducted methods, it was found that the researched future psychologists, who are oriented to practical activities under the guidance of mentors, have inadequately inflated self-esteem, an average level of cognitive activity, and an average level of anxiety during training, which correlates with an insufficient level of development of their professional self-identity. This indicates an inadequately inflated self-esteem, insufficient self-determination, inadequate self-satisfaction, self-expression, and insufficient self-regulation of the subjects during training. Therefore, it is necessary to pay special attention to creating conditions, finding means to increase opportunities for future psychologists to achieve a conscious, positive professional identity at the stage of educational and professional training, as this is an important basis for the effective formation of their professional identity in the future, as future reliable qualified specialists, the professional level of which will meet public demands, the needs of psychological assistance to victims of the war in the country.
