The object of this research is the student activity which has been organized and directed by the DCE of UFRuralRJ for the last twenty five years. The empirical material of this investigation was the collected testimony through interviews with former students who had command position in the students activity during that studied period of time. They were also in change of leadership positions at DCE. This way we tried to restore the social memory of these students who remember and reinterpret their own existences and experiences. The study analyzed the meaning given by the militants to their political performance and this influence on the professional and academic development. It also stood out the importance of such performance in their life experience and society perception. The student activity is investigated as a privileged entreaty of professional and academic development in the acquisition of university habitus and it is also investigated as part of strategies of distinction inside the institution. The social origin and the school trajectory emerge as an important influence on the student`s willingness to enter the student activity, reinforced by the intense conviviality at the campus. The process of construction of student`s investigated representation and ways of life aims at the core of student activity in the trajectories.
