The present work aims to investigate if there is a presence of illegitimate discourse as a form of discursive manipulation in a document that guides and directs the Brazilian education, the National Curricular Common Base (BNCC). The research collected data through the first version of the document and the approved version,
using as a theoretical methodological approach the contributions of Fairclough (1995, 2001, 2003), Chouliraki and Fairclough (1999) and the power relations in this discourse proposed by van Dijk (1997, 2010, 2012) and Falcone (2008). In the light of the Critical Discourse Analysis and with three-dimensional analysis method, we
investigate if the BNCC is interspersed with discourses with ideologies prone to affirm inequalities and contribute with an antidemocratic and individualistic world view. On a watchful eye to the rights of learning, and now general competencies of the National Base, we intend that this work contributes in a significant way to clarify doubts and certain insecurities related to the discourse proposed by the document that is part of school routine in the whole country.
