A French immersion teacher teaches students who do not normally speak French. French immersion schools instruct children whose parents want them to take lessons in French rather than English. Ontario French immersion schools usually follow a curriculum of all-French courses, including math, geography and science, except for an English language arts class. These schools are common in Ontario and other Canadian provinces, since the concept promotes bilingualism. Bilingualism, proficiency in both of Canada's official languages, supports the culture of a French-Canadian country and enhances an individual's job prospects. French immersion teachers require multiple years of training at recognized institutions.
