The present thesis, entitled Relations and bureaucratic styles in the public policy of mediaeducation in the municipality of Rio de Janeiro between 1993 and 2016, is an exploratory study on the performance of high and middle level echelons bureaucrats of the Secretariat of Education of the Municipality of Rio de Janeiro and MultiRio in the Mediaeducation policy in the period from 1993 to 2016. In view of this, it aims to understand how the bureaucrats performance styles influenced the production of the studied municipal policy, considering their individual characteristics, the contextual and institutional factors in which they act and the networks of relationships they constitute, as well as the influence of these styles in the process of formulation and implementation of this policy. In order to achieve this, we conducted a documental research and semi-structured interviews with the bureaucrats involved with the policy. We assumed as theoretical reference Lotta (2010, 2018), Marques (2000, 2004), Capela (2015), Kingdon (1995) and Mintrom and Norman (2009). The results of this study indicate the importance of context and local actors in the production of the Mediaeducation policy of the municipality of Rio de Janeiro. Furthermore, in what weights the existence of federal initiatives (Proinfo, TV Educativa, Salto para o Futuro program) and international influences (UN, Unicef, Unesco, OCDE) in this field, this study contributed to highlight the importance of institutional, relational and of the styles of bureaucrats at the high and middle echelons in the formulation, implementation and results of the Mediaeducation policy in Rio de Janeiro. From this, it was possible to identify three phases in MultiRio s performance in this production. The first one is defined by MultiRio s vigorous presence in the school network and its collaboration relations and sharing of responsibilities with SME. The second one presents the existence of media projects in dispute between SME and MultiRio. Consequently, MultiRio s performance became fragilized in the implementation of the municipal educational policy. In the third phase, the Mediaeducation policy ended up becoming more insulated in SME/RJ, which promoted a series of initiatives involving mediaeducation while at the same time MultiRio s leading Role was emptied out. It can also be perceived that the municipal executive power contributed, throughout the different studied periods, to create constraints and possibilities for MultiRio s performance in the Mediaeducation policy.
