Stereotypes are social representations that help us understand the world around us, and yet endanger our conception of the world. Indeed, using stereotypes can lead to generalisations; in other words, it can lead to neglecting the personal characteristics of individuals. This article studies gender stereotypes and their part in the French early school system; kindergarten. In France, school is mandatory from an early age and promotes equality. Yet, gender equality is hard to reach as long as gender stereotypes persist. The overall question this paper addresses is that of gender stereotypes in French schools' hidden curriculum: does it help construct them, deconstruct them, or is it neutral? This study, in which school books and online video recordings were observed and analysed with the concepts of stereotypes, counter-stereotypes and non-stereotypes, shows how gender stereotypes still exist in French kindergarten schools, although counter-stereotypes and non-stereotypes are found as well.
