This work approaches an unusual discussion in the Brazilian educational research, involving knowledge, school education, Sociology teaching, and interculturalism. Specifically, the work focuses the public high-school Sociology teachers opinions about the dialogues between the Sociology knowledge and the project of the intercultural education, considering the conceptions from Boaventura de Sousa Santos, Vera Maria Candau, and Antônio Flávio Moreira. There are two research goals: (1) to identify the high-school Sociology-teachers representations about the Sociology knowledge which is normally taught at the Brazilian Schools and its relationships with the intercultural education; (2) to propose some possibilities of creating Sociology public high-schools curricula under the intercultural concepts. Semi-structured interviews with eleven Social Sciences licensed-teachers who have been working at public high-schools in Niterói City (State of Rio de Janeiro) for at least two years were made. In addition, the official curricula documents concerning Sociology teaching and high-school education were analyzed. Linking the achieved data with the theoretical references, some important results were found. Although the analyzed documents point many propositions around the intercultural constitution of the Sociology teaching, content choices and the pedagogical practices are not usually affected by the intercultural education. At this scenery, building a high-school Sociology teaching under intercultural ideas remains as a non-reached goal, which is plenty of challenges to be faced by the educators.
