For many years, public participation has been a very popular subject of research and of interest for practitioners. Little attention has been devoted, however, to the issues of formal and organizational tools of managing this process. The paper contains the results of research aimed at creating the concept of participation infrastructure and at measuring its application in 17 Polish cities. For these purposes, the authors develop their own method of examining the practical use of participation tools. Typologies of participation tools are created and cities are classified according to their advancement, basing on the results of the research. The most popular and most willingly used tools are indicated, together with the levels of their implementation.
