French Immersion (FI) is an educational program where English-speaking students learn curriculum subjects primarily in French, developing functional bilingualism alongside academic knowledge. Programs typically begin in kindergarten (Early French Immersion) or Grade 6-7 (Late French Immersion), with French instruction gradually reducing in higher grades as English courses are added. Students learn mathematics, science, social studies, and other subjects in French, becoming bilingual through immersion rather than just language classes. French Immersion has grown substantially since its 1960s origins, with strong parent demand often exceeding available spaces. Benefits include bilingualism, cognitive advantages, and enhanced career opportunities in a bilingual country. Challenges include accessibility (not all areas offer programs), resources (specialized teachers required), and questions about student retention and outcomes. School boards manage enrollment and lottery systems when demand exceeds capacity.
