We present the results of the study of the actors' personality development psychological characteristics. It was hypothesized that the analysis of the similarities between individual profiles of student-actors can reveal personal typological features at the stage of selection and training in theatrical college. Sample: students of the theatre college, 129 students at the beginning and 117 - at the end of the 1st year, 64 - second year, 54 - third year, and 41 - fourth year students. Methods: R. Cattell's 16 Personality Factors Test. Results: we identified personal characteristics that manifested themselves at the stage of admission to college and inhibited successful professional development: rejection of authorities, desire to dominate, refusal to cooperate and work together. Cluster analysis revealed four personal types of student-actors related to theatrical roles. The following strategies of pedagogical influence manifested in the process of work with college students: individualization of training, transfer of professional knowledge through senior students. Conclusions: the study proved the efficiency and feasibility of using the method of cluster analysis and typological approach in the study of acting talent.
