In the past, access to education was at the centre of many collective claims made by the women’s movement. Today the scholastic success of girls is one of the most remarkable results of this. In the Québec context, the study of family dynamics shows how "day-to-day feminism" is the primary reason for this success. However, for the past ten years or so, a masculinist counter-discourse has appeared in the media, focussed on "the scholastic difficulties of boys", inspiring a large variety of school projects. The analysis shows that these interventions are designed from essentialist and naturalizing ideas about masculine identity. Moreover, the inefficient scholastic performance of boys reveals that they have a completely different agenda: to recover their lost masculine privileges. Thus, education is at stake in the social relationships between the sexes, where they battle for the places they will hold in tomorrow’s society.
