The subject of this final work is the implementation of the system of promotion in police administrations. The aim of the paper is to investigate the advancement of police officers as civil servants in police administrations with regard to the specificity of the police service. The strategic commitment of the Ministry of the Interior is to build a transparent human resources management system and arrange police service. The paper focuses on two progressive systems: both automatic and open, and within them, on the progression: in salary, occupation and workplace according to the hierarchy. In this connection, the fact that the police service is a hierarchical organization (principle of subordination) comes to the fore. In addition, the police service is also a career service (upon entering the police service, every employee must clearly recognize what his / her personal career development potential is). The progress of police officers is being analyzed in particular: regular, extraordinary and extraordinary promotion. As police administrations represent administrative organizations, the theoretical part of the work is backed up by a practical example of a progress system for the Police Administration in Bjelovar-Bilogora
