This study has as its objective to analyze the internship supervision as an integrant part of the labor process of the social assistant nowadays. To achieve this we took in consideration the transformations that are occurring in the world of the work and its consequences for the Social Work as much as in the sense of the graduation of social workers as in the sense of the performance of these professionals.Thus the comprehension and the reflection about de internship supervision and the challenges that the Social Work faces nowadays are central aspects of this study. On the other hand, it was possible to observe that the internship and its supervision are suffering similar impacts of those suffered by the Social Work in reason of the transformations that are occurring in world of work. Specifically we sought to know how the training fields of the PUC-Rio Social Work course are addressing the question of the mediation between theory and practical application in the context of the internship policy adopted in the first semester of the year 2009. Therefore we traced profiles of the internship supervisors and it was also necessary to identify the comprehension about the theme labor process. That was accomplished in such way that was possible to understand how the ethical-political dimension of the profession is expressed in the supervision process and also as a contribution for the construction of new strategies in the direction pointed out by the curricular directives of the Associação Brasileira de Ensino e Pesquisa em Serviço Social (ABEPSS). The methodology was qualitative and quantitative and we used interviews as well as documental analysis.
