The results of analytical studies of the subject and subjectivity in relation to law enforcement officers based on the academicians Eddy V. Sayko and Anatoly A. Derkach’s fundamental research are presented in the article. Service in the internal Affairs bodies is a deterministic system. It is characterized by huge information flows, extreme neuropsychic and emotional loads, and complex interpersonal relationships. In this regard, increased requirements are imposed on employees of all levels of the law enforcement system. After studying the long-term dynamics of the level of readiness of cadets of educational organizations of the Ministry of internal Affairs of Russia in the framework of self-development, it can be concluded that specialized competencies formed in the classroom according to the traditional system are not transformedinto skills of the highest order. Based on the research, the obvious problem of further improving the methodology of teaching competent actions in the course of performing operational and service tasks in various conditions is revealed. It is reasonable that the traditional learning process involves the development of a specific algorithm of actions in standard situations of operational and service activities, and when introducing various tasks of modeling typical situations, students often cannot complete the task in changing conditions (beyond the standard).
