French immersion: start early, start late or start at home

French immersion means learning in French instead of only learning about it: you use the language to do something else, such as study maths or live with a host family. This page explains how school programs work, what the published research says, what adults can do, and how to choose. For the audio side of immersion at home, see French listening practice. For the theory behind it, see French comprehensible input. For how many hours it takes, see How long does it take to learn French.

What is French immersion?

French immersion is a way of teaching in which the language of instruction is French. In the first Canadian program, a kindergarten class in Saint-Lambert, Québec, in 1965, children received the usual curriculum, with all the material taught in French [1]. The teachers were generally native speakers of French who understood English [1].

That is the “French immersion language” in a school: French is the medium, not the subject. In a Core French class, by contrast, French is taught as a subject [1]. The same idea runs through the adult options below: the French is the working language of the day.

What are French immersion programs and schools?

French immersion programs differ by when the child starts. The Canadian Encyclopedia describes three main types [1].

In early total immersion, the first phase is usually kindergarten to Grade 2 or 3 and all materials are in French. The second phase, to about Grade 6, uses English and French equally. The last phase, usually Grade 7 to the end of secondary school, offers 3 to 5 subjects in French [1].

A “French immersion school” can be a whole school or a stream inside an English school. The sources here do not give one count of each, so check how your district sets it up.

How big is French immersion in Canada?

In Canada the figures are public. In 2023/2024, French immersion made up 11.6% of total enrolments, down from a peak of 12.3% in 2020/2021 [2]. Statistics Canada notes that comparisons between provinces and territories need caution, because reporting practices differ [2].

The Canadian Encyclopedia adds a limit: as of 1999, a large majority of English-speaking students learned French as a subject rather than through it [1].

Where can you find French immersion schools near you in the US?

Start with the French-government network. Villa Albertine says public schools across the United States offer French immersion and bilingual programs, serving more than 33,000 students in 180 schools across 30 states [3]. It links an interactive map of the network [3].

The same page describes the Label FrancEducation, an accreditation from the French Ministry of Foreign Affairs. To earn it, a school must teach a minimum of 20% of subjects in French and meet other criteria, including certified teachers [3]. A school without the label can still be a good program. The label is one signal, not the only one.

Local districts publish their own rules. One US example, Montgomery County Public Schools in Maryland, says selection for its immersion programs is by lottery for kindergarten and Grade 1 when requests exceed capacity [4]. Your district may work differently.

What does the research say about French immersion?

Both studies below are Canadian, and each looks at a specific group.

A study in the Journal of Child Language followed English-speaking children from Grade 1 to Grade 3, matching teacher-nominated at-risk readers with not-at-risk readers in immersion and English programs [5]. Children in immersion had higher final status in phonological awareness and in decoding. At-risk readers in immersion had faster growth and higher final status in reading comprehension [5].

A study in the International Journal of Bilingual Education and Bilingualism looked at English-speaking children in an intensive French immersion program, in Grades 2 and 5 [6]. Vocabulary and grammatical knowledge stayed higher in English, even after five years of immersion in French [6]. Measures of metalinguistic ability in French improved and closed the gap or caught up with English [6].

What is a French language immersion program for adults?

Adult options split into two kinds: a course where French is the daily language, and a routine you build yourself.

One official example is Université Sainte-Anne in Nova Scotia. Its Integrated French Immersion Option lasts 1 to 2 years. A placement test puts you into one of two levels, each a semester, with three French-as-a-second-language courses and two in your degree program [7]. Students sign a pledge to speak French at all times during the program [7]. The page says the option suits students who already have a certain level, for example a B1-level DELF diploma or French immersion in high school [7]. For people with little or no French, it offers credited spring and summer immersion sessions and year-round courses [7].

That is one university, not a ranking. Check each provider’s own page for dates, levels and conditions. If you are in Canada and want public classes, see Learn French in Canada.

What is French immersion in French? An at-home routine

“French immersion in French” can also mean making your own day happen in French. These steps are general practice, not a published method.

• Change your phone and apps to French.
• Listen to something in French on every commute. Pick audio you mostly follow; see French comprehensible input.
• Speak out loud, even alone: ordering, thinking, narrating.
• Keep a short list of words you meet every day and review it.

Here are five words you will hear in almost any French room. Press play to hear them.

How do you choose a French immersion option?

Choose by age, start point and time you can give.

• For a child: ask the school how many subjects are in French, from which grade, and whether the program is a whole school or a stream. Ask what support exists for families who do not speak French.
• For an adult at beginner level: a credited short session or regular classes is the entry the Sainte-Anne page itself points to for people with little French [7].
• For an adult at intermediate level: a longer program with a French-only rule is open to you [7].
• For anyone: pair the course with daily home contact, and set a level you can name. French levels explained helps with that.

Common mistakes

• Treating a French class as immersion. In Core French, French is a subject, not the language the school day runs in [1].
• Assuming one program works the same everywhere. Start grade and the share of subjects in French differ [1][3].
• Reading one study as a promise. Each study reports on its own children and program [5][6].
• Using this page’s numbers without a date check. Compare the date on each official page with the date at the top of ours.
