This paper performs a summary about the context of publication of the National Curricula Standards, and attempts to draw parallels between some elements of the context and the affiliations of these documents to the contents that they propose, and the problems and possibilities that they bring to the teacher's work (recompose the contents, contribute to the pupil's development, preparing them to the National Evaluation of the Secondary Level - ENEM and admissionary exams to the superior level). The objective is to demonstrate that the ENEM, among other evaluative practices created at Fernando Henrique Cardoso period (1995-2002), plays an organizational paper to the curriculum of secondary education, and therefore makes an important factor at the choosing and dosing of historical knowledge operated next to the growing group of the Brazilian population, who completes this educational level.
