<p class="RESUMENCURSIVA">Studies of youth public participation have dealt with varied conceptions of citizenship that emerge from literatures on human rights, civic engagement, youth development, and youth organizing and activism. Where those conceptions rely on developmental logics that limit or exclude youth participation, young people’s attempts to gain authority reveal concurrent ways they navigate these multiple conceptions of participation. Drawing on an 18-month ethnographic study, the analysis presented here focuses on a specific venue for youth participation: a student advisory board. Data includes participant observation, interviews, and artifacts including resolutions and emails. Twenty-one of 27 students, representing roughly 15 high schools in their school district, participated in the study. When students attended to paperwork like bylaws and the state education code, they gained access to contingent authority, a limited but influential form of Weberian authority. Key implications of the study indicate that while youth advisory councils can reliably produce exclusion on developmental grounds, they can also provide the parameters for establishing contingent authority. Paperwork is a key to accessing this form of bureaucratic authority, but exercising it requires sustained, public practice.
