In 2007, an innovative school program, “Option-études Châteauguay”, was launched, offering a unique opportunity for Quebec secondary school students educated in linguistically divided school boards to come together in a shared second-language learning experience. More specifically, it allowed students to crossover to the other educational sector and spend half the year in a French-medium school and the other half in an English-medium school, while respecting the educational clauses of Quebec’s Charter of the French Language. This program is unique in two ways: it is based on an intergroup contact model developed in social psychology; and it brings together students in a shared schooling experience in their second language, organized around themes that draw on common interests, such as sports and entrepreneurial studies. A qualitative and longitudinal research study assessed the perceived short- and mid-term impacts of this experience on students’ intercommunity relationships and identities.
