Actually the public policies management depends upon the establishment of partnerships between public power and civil society’s organizations. At the same time in which one tries to constitute more public parameters in the policies management, occurs the growing uses of service’s indirect executions and focused expenses mechanisms. Through the case analyses of São Paulo’s social assistance policies we intend to answer these following questions: In this context, which limits are imposed to the State in the policies implementation? The fact that the social assistance policy in São Paulo’s city depends on the shared actuation between public power and civil society would not insides directly on the policies focalization strategies claimed by the public power? Which are the limits that these considerations reveals for the social services executed through the partnership between State and civil society’s organizations? Beginning from official data, we produced one territorial and sectorial characterization of the social assistance network existing in the city. Confronting this data with the social vulnerabilities references – used by the public power to define the policies focalization areas – we have concluded that the public power can not accomplish the focalized policy strategy of management in the social assistance area of the municipality.
