At the moment in Poland, specialised dispositional groups such as the armed forces, the police, and various guards and other services are constituted. The fundamental tool that the state has at its disposal to counteract potential threats to internal security and public order, and to react appropriately to existing threats is a separate body — the police. The main objective of this paper is to define the practical benefits which can be gained as a result of organising cooperation between the police units mentioned above in an appropriate way. This paper is an attempt to present practical cooperation between a local police unit and the Police Academy in Szczytno. It also points out the distinct nature of functioning of the Regional Police Headquarters in Katowice and its dependent units; it describes the impact that cooperation with an educational institution has on the quality of preserving public security and order as well as the practical aspect of such cooperation on the example of the organisational units of the Polish National Police specified above.
