This research intended to reflect on how the gender issue is addressed in the curriculum documents NCPandNCP + elementary and middle school . Firstly I delve into the literature of gender studies and curriculum, seeking to understand how these two fields intersect in order to identify how issues relating to gender and sexuality became a topic of curriculum area. Then, the critical assessment of the data, primarily based on the methodology of document analysis and content analysis and questioning the NCP and NCP + trying to understand how the issue of gender is discussed, trying to identify what their place within the documents. The main conclusions of the research are: (1) the concept of gender revealed in the analysis of the documents is marked by a design that favors the dichotomy between nature (sex) and culture (gender), (2) curriculum documents have a hygienist perspective on sexuality and the body, with a strong emphasis on the practice of safe sex and (3) women - as subjects historical and analytical category - are in the texts of the NCP and NCP +.
