This research aims to define the profile and analyze the personal and professional path of Social Work s graduate students, supported by affirmative actions promoted by PUC-Rio. The premise is that higher education completion, driven by affirmative action policies, positively boosts the transformation of social relationships, modifying probable path of those individuals, in what concerns social mobility. In order to reach proposed objective and based on indications from empirical field, we chose a descriptive research of quanti-qualitative nature. For data gathering, we did a survey using a form filled by Social Work s graduate students, enrolled in the period from 2000 to 2010. Herewith, quantitative data and an extensive documentary and bibliographical collection were analyzed jointly. At the end of this research, we realized that the individuals, coming from lower class, have actual possibilities of access to higher education, through affirmative action policies and, because this opportunity, they can stop a perverse cycle of exclusion. They transform their own life paths, changing the deterministic forecasts about their future considering social class. Thus, they become positive examples for their families and neighborhood, successful references and genuine examples of social mobility.
