The article presents some advances of the research project on Practices of the Youth as Citizen Expressions. From the analysis of three university student groups taken from the 20 groups of youths that participate in this mixed method combining ethnographic strategies with narrative and discursive analysis, the article describes the trajectory and the practices of these groups and shows how the students live experiences that ease the development of different citizen expressions and abilities. The conclusions state that the creation, support and agency of these groups in the universities represent a way to encourage the formation of citizens, and some suggestions are presented related to this topic.
