French as a Second Language (FSL) encompasses educational programs teaching French to English-speaking students. FSL programs take several forms: Core French provides French instruction as a subject for set periods daily; Extended French increases French instruction time and may teach some subjects in French; and French Immersion provides most or all instruction in French. These programs support Canada's official bilingualism policy and help students develop French language skills for personal, academic, and career opportunities. In English-language school boards, FSL programming is mandatory at certain grade levels, with optional intensive programs available where demand and resources permit. FSL differs from Francisation or Français Langue Seconde programs in French-language schools that help newcomers learn French. Program availability and quality vary by school board, and teacher shortages affect FSL delivery in many jurisdictions.
