摘要:The Socio-Educational system is the policy of care for juvenile delinquents in Brazil. This policy is challenged to differentiate the prison system, because it’s pedagogic and sanctionatory in the same time. In this paper we propose to make a critical analysis of the implementation of the policy of children and adolescents in Brazil, especially the socio-educational system, under a critical view, with foundation in dialectical historical materialism. So we present the historical evolution of the attention to the rights of children and adolescents in Brazil and aim the limitations and possibilities of this policy today, in addition to the current operation of this policy, followed by an analysis based on critical criminology. Finally, we indicate that the juvenile justice system, the socio-educational system and all social practices relating to offenses should be seen as part of an historical and social process that has as its central point the materiality of social relations, the relationship between society, market and State and the consequent contradictions that are placed there. As the socio-educational project is linked to a contemporary neoliberal state, he does not escape the pressure of capitalism. That is, you can not understand the socio-educational institutions and logic that supports policies so displaced from this broader socio-political system that perpetuates unevenly and exclusive.
