The elaboration of policies and the provision of public services are increasingly shared between public and private actors, constituting a governance network. The work aims to analyze the model of public-private relations in the construction of educational policies in the State of São Paulo, based on references on the governance network, neoliberalization and the heterarchization of the State. Using the methodology of network ethnography, an analysis instrument that enables the representation of networks in graphs, we sought to map the new forms of privatization evidenced from programs of the São Paulo State Department of Education (Seduc) that had the participation of private agents in its elaboration and implementation, namely: 1) Programa Educação - Compromisso de São Paulo, in partnership with Associação Parceiros da Educação; 2) Inova Educação Program, in partnership with Instituto Ayrton Senna; and 3) New Medium School in São Paulo.
