French immersion is a form of bilingual education in which a child who does not speak French as his or her first language receives instruction in school in French. In most French-immersion schools, children will learn to speak French and learn subjects such as history, geography and science in French.

The Agence pour l'enseignement français à l'étranger (AEFE) runs or funds 470 schools worldwide, with French as the primary language of instruction in most schools.

French immersion is used in Australian schools such as Mansfield State High School; teaching mathematics, SOSE, science and French, entirely in French.

There is also a French immersion program offered at Methodist Ladies' College and Benowa State High School teaching a variety of subjects over three years in French.

Telopea Park School in Canberra is a bilingual French-English school.

The program is also offered at The Glennie School in Toowoomba Queensland

French immersion is offered in most Anglophone public school districts. Most early French immersion students, starting in kindergarten or Grade 1, do all their work in French, except English language arts, which usually starts in between Grades 2 and 4. Late immersion generally begins in Grade 5 or Grade 6, although these students are not usually in the same classes as early French immersion students. Some schools do not offer French immersion until later grades. Extended French programs provide a variation on late immersion, where students take some courses in English and others in French. French immersion is also done in some private schools and preschools.
