This thesis analyzes the main elements involved in the neoconservative action on national education. It investigates trends, inclinations, values and objectives related to conservative logic and its influence on the Brazilian educational political project. It also discusses the place occupied by religion in this context. The hypothesis that supports this work is that the rising Neoconservatism in Brazil uses education as a field for the dissemination of moral, religious, meritocratic and security values, to empty the school environment of its political and emancipatory component. The theoretical framework articulates national and foreign authors such as Ronaldo Almeida, Marina Lacerda, Noel O Sullivan and Michael Apple. Upon these works, we argue that Brazilian neoconservative activism is inspired by similar movements from other countries, especially from the United States of America in the 1970s and 1980s, adapting it to Brazil’s own specificities. As in the original context, education now occupies a place of great relevance and interest, given its capillarity and social importance. The methodological approach used is Content Analysis (BARDIN, 2016) of a set of documents: parliamentary initiatives related to education proposed between the years 2001 and 2020 in the Brazilian Chamber of Deputies, the Manifesto to the Brazilian Nation produced by the Evangelical Parliamentary Front in 2018, the inauguration speech of the current president Jair Bolsonaro and the decree implementing military civic schools. The results confirm the initial hypothesis by indicating the growth of conservative proposals over the years related to themes such as sexuality, religion, home education, school indoctrination and patriotism. Ultimately, the work shows that different projects of society and democracy are in dispute involving controversies about family, secularity, diversity, and educational aims. Its implications for Education point to teacher silencing, limiting the pluralism of ideas and breaking the boundaries between public and private, knowledge and opinion. The conclusion of this text synthetizes the ideas discussed and the points out future developments, such as the implications for the teaching of topics as biological evolution, reproduction, and sexuality. Themes that are of interest to religious ideological patrolling of neoconservative educational activities.
