This article is about the use of crowdsourcing in public sector. In many countries in the world, also in Poland, state authorities at various levels have sought effective ways to involve their citizens in public decision-making. The main objective of increasing civic engagement is to broadly promote trust in public authority activities and to build civil partnerships.

The author presents the model of key elements influencing the level of civic engagement.
