The project seeks to account for the negative effects of stereotypes associated with underprivileged social classes on the academic success of adolescents coming from these social classes. These stereotypes may not only lower academic results, a fact which has never been rigorously demonstrated in France, but also lead adolescents to self-censorship, limiting their ambitions relative to what their academic results permit them. The project also allows for the evaluation of the role of parents in the instigation of stereotypes in adolescents.
