Since the 1990s, Brazil has experienced the phenomenon of militarization of public schools, whose management is shared or transferred to the Military Police, Fire Department, or Armed Forces of Brazil. In the Federal District, the local government proposed through Decree number 01 of January 31, 2019, the shared management program of public schools with the Military Police of the Federal District, which tends to expand with the federal government's Civic Military Schools Program, approved in the same year. This program has generated debates because it is a recent experience and because of the polemics surrounding school militarization, especially regarding the organization of pedagogical work. It was assumed that the class council, a space-time for student evaluation and school work, could be influenced by the militarization of the school. Thus, this dissertation, which integrates the set of scientific productions developed by the Group of Studies and Research on Teaching, Didactics, and Organization of Pedagogical Work - Prodocência, within the Postgraduate Program of the School of Education at the University of Brasilia, in the Research Line: Teaching Profession, Curriculum, and Evaluation, had as its central research question: what are the conceptions and practices of the class council in a militarized school in the Federal District? As a general objective: to analyze concepts and practices of the class council in a militarized school of the Federal District. The specific goals are: a) identify how the class council is portrayed in official documents; b) reflect on the meanings constituted by teachers, pedagogical managers, disciplinary managers, and students about the class council in a militarized school; and c) understand the development of the class council in a militarized school.
