This research investigates the role of developer teachers in the elaboration of the Cadernos Pedagógicos de História da Secretaria Municipal de Educação do Rio de Janeiro (SME/RJ) (History Pedagogical Materials of the Municipal Education Secretariat of Rio de Janeiro), in order to integrate the official policy and the necessary resources for teachers to work in the classroom. The context of the research was a new educational policy developed for the municipality of Rio de Janeiro, which led to changes in the curriculum of schools. The theoretical references include: policy cycle approuch by Ball and Bowe (1992), curriculum policy concepts by Lopes (2004), concepts on resource materials and textbooks by Bittencourt (2011a, 2011b) and Munakata (2007, 2012). The methodology followed the principles of a qualitative study, using interview held with the five members of the team that developed the Cadernos Pedagógicos de História da Secretaria Municipal de Educação do Rio de Janeiro SME/RJ, for data collection. The conclusions revealed that even when facing a prescriptive curriculum policy and awards policy, the elaborator teachers sought to create resource materials suitable to the needs of municipal school teachers and students. This team defended the teachers freedom in the use of resource materials and aimed to produce support resources to help them with new ideas, texts and appropriate activities for the students. Thus, it is possible to state that the actions of the elaborators of Cadernos Pedagógicos de História – in the context of text production – have changed the policy.
