The article stresses the discursive similarities between the National Curricula Parameters (PCN) established by the Brazilian Ministry of Education, considered the official curriculum, and the School Assembly Movement inspired by the Workers' Party state government in Rio Grande do Sul, proposed as an alternative curriculum. It discusses what has been happening with our critical alternative curricula which end up proposing almost the same education as that of the Federal Government. It forwards the argument that, as a consequence of this hybridism, we need to dispel the ambiguity, by producing and putting into practice curricula which do not yet exist and to invent once more the difference.
