The French level required for naturalisation: B2, spoken and written
The level required for naturalisation changed on 1 January 2026: it went from B1 to B2, and it is asked in both skills, spoken and written. It is the highest level of all the residence procedures, and it is the only point on which this site can help you: we prepare you for a language test, we do not process any application and we do not judge any decision in advance.
Not sure whether a level is required from you, or which one? The simulator starts from your situation and answers in one minute.

B2
B2 spoken and written, both required.
The Service-Public page asks for both skills and does not allow one to make up for the other: excellent writing does not make up for weak speaking. This is what makes this procedure more demanding than the resident card (B1) or the first multi-year permit (A2).
Your level is not just declared: it is proved, with one of these documents.
a TCF or TEF certificate less than 2 years old
the brevet (diplôme national du brevet)
a state diploma at level 3 or higher (CNCF classification)
a professional certification (RNCP) at level 3 or higher
any diploma showing a level equal to or higher than B2
The TCF IRN is the version of the TCF designed for these procedures: it is the most direct route if you have none of the diplomas above. The exact list of documents accepted for your situation is on the Service-Public page. That page is the reference, not us.
Exemptions: be careful, they are not the same as for a residence permit
This is the most common mistake in these procedures. The exemption from age 65 exists for the residence permit, multi-year or resident card. It does not exist for naturalisation. Age alone never exempts you from a naturalisation application.
Age
No exemption at 65. The people exempt are refugees with official status who are 70 or older, and who have lived in France for 15 years or more.
Health
A disability or a health condition that makes the assessment impossible, shown by a medical certificate.

B2, translated into exam results
If you take the TCF IRN, this is what "B2" means in each of the four tests. This is your target, in all four.
The certificate also shows an "overall level reached: YES / NO" ("niveau global atteint : OUI / NON"), calculated by France Éducation international from the four tests. The rule for this calculation is not published: nobody can work it out, and we do not try to. The only safe strategy is to aim for B2 in all four tests, without counting on one making up for another.
The plan: 6 weeks, in this order
Six weeks: the exam format, administrative vocabulary, the three writing and speaking tasks, and the interview. You start and finish with the full mock test.
Week 1
Measure the gap, learn to read an application file
You cannot prepare for B2 without knowing where you start from. The full mock test gives you the starting point; the whole programme is read from it. At the same time, we start on the vocabulary that comes up in all procedures: the words of the documents to provide.
Understand an administrative text without rereading it three times
Reading comprehension is the longest of the four tests (35 minutes) and one of the two that can never be recovered: the multiple-choice answers are not marked again. An administrative document reads quickly when you know its words; otherwise you reread it, and time runs out.
In listening comprehension, each recording plays only once. And in the speaking exam, as at the counter, a question asked in a formal register ("pourriez-vous préciser...", meaning "could you specify...") blocks you more often than the vocabulary itself: you do not understand what is being asked.
Write at the expected level: register, not only grammar
At B2, spelling is no longer what sets you apart: it is the ability to structure an opinion and keep a register. Three tasks in 30 minutes, with a required number of words. Outside the limits, the task is rated "A1 not reached", whatever your French.
The TCF IRN speaking test takes place with no preparation at all, and reciting a learned text is rated "A1 not reached": the examiner is told to interrupt. So we practise having ideas ready to use, never learned sentences.
The last questions of each test are the hardest: opinion articles, talks at normal speed. We work on them last, then take the full mock test again in exam-day conditions: 1 h 35, no break, no dictionary.
The interview at the prefecture: practise it out loud
Your level is proved by a document; the interview, however, takes place in French, spoken, with someone who follows up on what you say. The simulator lets you live through this quarter of an hour: an officer asks questions by voice, you answer into your microphone, they pick up on your answers, and your French is corrected answer by answer.
It works on your French, never on your application: no knowledge questions, no opinion on your motivations.
A civic exam is now added to naturalisation, the resident card and the first multi-year permit. It is separate from the language test: the TCF IRN only tests French, never French history, culture or society.
We do not prepare for it yet. On our side, its official programme has not yet been checked against a primary source, and we will not write a training page for a programme we have not read.
The full TCF IRN mock test and two vocabulary series stay free, for everyone. The Pass opens the 20 series, the TCF IRN practice sets and the automatic correction of your writing and speaking.
What level of French exactly is needed for naturalisation?
Level B2 of the Common European Framework of Reference, spoken and written. Both have been required since 1 January 2026; the level asked before was B1. The Service-Public page F11926 does not allow one skill to make up for the other.
I am over 65: am I exempt from the French test?
Not for naturalisation. This is the most widespread mistake in these procedures: the exemption at 65 applies to the residence permit (multi-year or resident card), not to naturalisation. For naturalisation, only refugees with official status who are 70 or older and have lived in France for 15 years or more are exempt. An exemption for health reasons also exists, with a medical certificate.
Which exam do I have to take?
The TCF or the TEF are the two recognised certifications, valid for 2 years. The TCF IRN is the version of the TCF designed for immigration and nationality procedures. If you already hold the brevet, a state diploma at level 3 or higher, an RNCP certification at level 3 or higher, or any diploma showing a level at least equal to B2, you do not necessarily need to take a test: check the exact list on the Service-Public page F11926.
Is my 2023 TCF certificate still valid?
A TCF or TEF certificate is valid for 2 years from the date the results are issued. After that, it can no longer be submitted and the exam must be taken again. Check the issue date shown on the certificate itself, not the date you took the exam.
Do you also prepare the civic exam?
No, not yet, and we prefer to say so. A civic exam has been added to the procedures since 1 January 2026, but we have not yet checked its programme against a primary official source. We will not publish training for a programme we have not read. The TCF IRN, for its part, only tests the language: no history, no culture, no society.
How long does it take to go from B1 to B2?
Nobody can give you an honest figure: it depends on your real starting point, the time you spend on it and how much French you hear every day. What we can say is what the six-week programme covers: the four tests, administrative vocabulary, and two sittings of the full mock test to measure the gap at the start and at the end. If the gap is still large after the first mock test, it is better to spread the programme out than to squeeze it.
Do you also prepare the interview at the prefecture?
Yes, for the language part. The interview simulator puts you in the situation: an officer asks questions by voice, you answer out loud, they follow up on your answers, and your French is corrected. It asks no knowledge questions and gives no opinion on your application: the Service-Public page F2213 describes the interview, and that page is the reference.
Do you process naturalisation applications?
No. Mon Coach de Français is an independent site: it prepares you for a language test, it does not submit any application, does not register you for any exam and does not issue any official document. The conditions for access to naturalisation, apart from the French level, are covered by the Service-Public page F2213 and by the prefecture, not by us.
Is administrative vocabulary really useful for the exam?
Yes, in two ways. The documents in the TCF IRN reading test are partly administrative messages and letters: this is exam vocabulary. And once the exam is over, these are exactly the words of your letters and your appointments. It is the only vocabulary you will use twice.
Information checked on 20/08/2026 on pages F11926 (citizenship: proving your French level) and F2213 (naturalisation by decree) of Service-Public.fr. Conditions for naturalisation other than the French level are not covered here: see those pages and your prefecture. Rules change: check the source before you apply.
Grammar rules are explained in your language when French is not enough yet.
