The article reveals the process of development of a new professional and communicative identity of future patrol police officers. The aim of the research is to study the types of behavior in the professional environment and identify the experiences associated with the work of the police at the initial professional training stage (students) and after six months of work (patrol policemen). The research involved 302 patrol police officers, the first group – 177 students, the second group – 125 patrol policemen. The results of the study indicate differences in the indicators related to the experience of future police patrols and those already working. We have identified dominant spheres of personality and types of behavior of policemen. It is argued that the beliefs of future police officers concerning the positive dynamics of events will meet their expectations, and therefore, it will contribute to harmonious professional and communicative development. The obtained results update the development of psychological technologies in order to optimize the development of the professional and communicative identity of the policemen at each of the stages of professionalization. In addition, they become the basis for the formation of active stress coping strategies and, consequently, the increase in professional performance. It is concluded that important prerequisite for the development of professional and communicative identity is the professional socialization and the period of training, because it is exactly at the initial stage of entry into the profession when it is important to create psychological and pedagogical conditions for self-realization in the future professional activities.Keywords: Patrol police, Professional and Communicative Identity, Professionalization, Types of behavior.
