This paper presents a review of the state of knowledge regarding Regional Normal Schools (CNRs) in Rio Grande do Norte. The study mapped the academic production on the history of these teacher training institutions, examining the gender relations that have historically influenced teacher preparation. The research involved consulting three institutional repositories and the CAPES Periodicals database regarding the institutionalization of Regional Normal Schools. The identified works include doctoral theses, master’s dissertations, scientific articles, and papers published in the proceedings of academic events in the field of Education. The study finds that research on gender relations in the teacher training provided by CNRs is still lacking, highlighting the importance of other proposals addressing these aspects and offering a significant contribution to a field of study that has not yet been prioritized in existing analyses.
