Abstract: The article is devoted to the analysis of psychophysiological and personality correlates of successful professional education of would-be operators. The data of the socio-psychological study and psycho-physiological examination of young people showed that in modern demographic and social conditions, young men often do not have sufficient prerequisites for achieving successful military-professional adaptation during the training period, which places increased demands on the functional state of the body and the personality of the cadets. These indicators should be determined at the stage of enrollment in a military school, as well as in the process of training in the framework of medical and psychological support for students. Taking into account the cumulative expert assessments, the cadets are divided into two groups of learning success: “more successful” and “less successful”. The research methodology involves a comparative study in groups. The success of the cadets mastering the curriculum and the formation of professional competencies, including mastering the skills of the communications operators, are related to the presence and severity of a number of psychophysiological and personal qualities: strength and high endurance of the nervous system, high mobility and balance of the nervous processes; the level of verbal and non-verbal intelligence, the quality of logical and spatial thinking, high-speed cognitive characteristics, indicators of productivity and reliability (efficiency) of mental activity; high level of neuropsychic stability, development of communicative and moral qualities; military professional orientation and low propensity to deviant behavior and suicidal risk.
