In most schools everywhere, democracy and participation continue to be carried out through the usual channels based on representative democracy and the vote of elected representatives. However, this reality is not monolithic, and we do find centers committed to practise a full and more profound democracy. Based on a case study, the article analyzes the theoretical and practical approach of Germinal School. Despite some difficulties, this school has successfully implemented a project of radical democracy, both through micropolitics and daily pedagogical action. This article also examines why it is so difficult to democratize school and how to create a truly democratic institution. Finally, we address the possibility of extending the democratic model presented here to other schools.
