TEF IRN: format, scores and the level you need in 2026

The TEF IRN is the version of the TEF that French authorities accept for a residence permit and for naturalisation. Two things about it changed recently, and most guides still have the old version: it now tests all four skills up to B2, and since 1 January 2026 naturalisation asks for B2 rather than B1. Here is the current format, how the scoring really works, and what to do about your weakest skill.

Official 2026 format and score bandsLevels required by French authorities90 minutes, four tests, one day

What changed, and why old guides mislead

Plenty of TEF IRN pages still describe an exam made of listening and reading only, capped at B1, with 60 listening questions and 50 reading questions. That exam no longer exists. The TEF IRN was extended to B2 in May 2025 and is now four compulsory tests sat on the same day. At the same time the bar moved: applications for French nationality filed from 1 January 2026 are assessed at B2 rather than B1. If you prepared from an older guide, you have very likely been practising the wrong skills at the wrong level.

What people still believe
  • Only listening and reading are compulsory
  • The exam stops at B1
  • Listening is 60 questions in 40 minutes
  • B1 is enough for naturalisation
What is actually true in 2026
  • All four skills are compulsory, on the same day
  • The exam certifies up to B2
  • Listening is 20 questions in 20 minutes
  • Naturalisation needs B2 in speech and in writing

What the TEF IRN is, and who needs it

IRN stands for Intégration, Résidence, Naturalisation. It is one of several versions of the Test d'évaluation de français run by Le français des affaires, the language arm of the CCI Paris Île-de-France, and it is the version built specifically for French administrative files. If a prefecture, a consulate or a naturalisation dossier asks you to prove your French, this is usually the TEF you need. A TEF Canada attestation does not stand in for it, so check that your registration and your certificate both say "TEF IRN".

You need it if
  • You are applying for French nationality by naturalisation
  • You are applying for a carte de résident
  • You are renewing onto a carte de séjour pluriannuelle
You do not need it if
  • You are applying to IRCC for Canadian immigration, where TEF Canada applies
  • You are enrolling at a French university, where TEF Études applies
  • You already hold a recognised French-language diploma at the required level
Good to know
  • The certificate is valid for two years from issue
  • All four tests must be sat on the same day
  • There is no partial retake, a resit means the whole exam

TEF IRN format: four tests, 90 minutes

Figures below are the provider's own. The whole paper is shorter than a single TEF Canada sitting, which cuts both ways: less endurance is needed, and there is far less room to recover from a bad start.

Reading (Compréhension écrite)
20 questions · 30 minutes
  • Multiple choice throughout, scored one point for a correct answer and zero for a wrong or missing one.
  • The documents are the ones you meet in an administrative life in France: notices, adverts, short press articles, letters from an institution.
  • At 90 seconds per item this is the most generous section of the paper. Candidates rarely run out of time here, they run out of vocabulary.
Listening (Compréhension orale)
20 questions · 20 minutes
  • Multiple choice, scored the same way as reading.
  • Short everyday recordings: announcements, messages, ordinary conversations.
  • One minute per item including the audio, so there is no time to replay anything in your head. This is the section where a single missed word costs a point.
Writing (Expression écrite)
2 tasks · 30 minutes
  • Section A: 10 minutes, at least 40 words. A short personal message.
  • Section B: 20 minutes, at least 100 words. A longer text where you have to develop and support a position.
  • The minimums are floors, not targets. Writing under them is the most common avoidable way to lose the section.
Speaking (Expression orale)
2 tasks · 10 minutes
  • Section A: 5 minutes. Section B: 5 minutes.
  • Face to face with an examiner, so the exchange is live and you are marked on how you respond, not only on what you prepared.
  • Ten minutes is short. There is no warm-up, and your first minute counts as much as your last.

How the TEF IRN is scored

Each test is marked from 0 to 499 and mapped onto the CEFR scale, where every level is 100 points wide. Reading and listening award one point per correct answer and take nothing away for a wrong one, so leaving an item blank is a pure loss.

The rule most candidates miss

Your level is not your average. Three tests have to clear the band, and your weakest test has to clear a separate, lower floor: 267 for B1, 367 for B2. A candidate scoring 460 in reading, 440 in listening, 410 in writing and 350 in speaking does not certify at B2, because the speaking score sits under the 367 floor. Practically, that means the fastest route to the level you need almost always runs through your worst skill, not your best one.

What level French authorities ask for

These thresholds moved for applications filed from 1 January 2026. Requirements are set by decree and prefecture practice varies, so treat the table as your starting point and confirm the current threshold for your own procedure before you book a seat.

Naturalisation (French nationality)B2

B2 in both spoken and written French. Your TEF attestation has to be less than two years old on the day you file.

Carte de résident (10 years)B1

B1, under the arrêté of 22 December 2025. Confirm the current threshold with your prefecture before you book, because practice varies by procedure.

Carte de séjour pluriannuelleB1

B1 under the same arrêté. The level attached to this card has been raised, so check what your own renewal is being assessed against rather than assuming the threshold you met last time still applies.

TEF IRN vs TEF Canada vs TCF IRN

The two mistakes that cost people a sitting: booking TEF Canada when the file asked for the IRN, and assuming the TCF IRN is an easier way round. It is not easier, it is a different provider running an equivalent exam for the same procedures.

How to prepare for the TEF IRN

The IRN is short, so preparation is less about stamina and more about removing the one skill that drags your certificate down a level.

1Find your weakest skill first, not your average

Your TEF IRN level is held down by your worst test. Someone at 430 in reading and 340 in speaking certifies at B1, not B2. Before you build a study plan, sit a full four-skill mock and look at the lowest number on the report, because that is the one your file depends on.

2Practise writing against the clock and the word floor

Ten minutes for 40 words, then twenty minutes for 100. Most candidates who lose the writing section either come in under the minimum or spend so long on Section A that Section B is unfinished. Write both under a timer until the split feels automatic.

3Rehearse speaking in five-minute blocks

Ten minutes total, split into two five-minute tasks, face to face. There is no warm-up, so practise starting cold. Recording yourself and listening back is uncomfortable and it is the fastest way to hear what an examiner hears.

4Do not guess-penalise yourself

Reading and listening give one point for a correct answer and zero for a wrong one. There is no deduction, so never leave an item blank. This alone is worth a few points to candidates who were taught to skip when unsure.

What Mocko does and does not offer

To be straight with you: Mocko does not have a TEF IRN paper that reproduces the exact IRN timings. What we do have is TEF practice across the same four skills, marked on the CEFR scale the IRN certifies against, with AI feedback on writing and speaking. That is the part that transfers, and it is the part most candidates need, because the IRN is decided by your weakest skill. The IRN-specific timings, word floors and task shapes are on this page so you can rehearse them yourself.

TEF IRN questions people actually ask

Does the TEF IRN test all four skills?

Yes. Since the exam was updated, the TEF IRN is made up of four compulsory tests: reading, listening, writing and speaking. All four have to be taken on the same day for the certificate to be recognised by French authorities. Guides that describe a listening-and-reading-only exam are describing the old format.

What level do I need on the TEF IRN for French naturalisation in 2026?

B2, in both spoken and written French. On the TEF IRN scale that means 400 or more on three of the four tests and at least 367 on your weakest one. The attestation has to be less than two years old when you file your application.

How long does the TEF IRN take?

About 90 minutes in total: 30 minutes of reading, 20 minutes of listening, 30 minutes of writing and 10 minutes of speaking. It is considerably shorter than TEF Canada.

How is the TEF IRN scored?

Each of the four tests is scored from 0 to 499. Reading and listening give one point per correct answer and nothing for a wrong or missing one, so there is no penalty for guessing. Your overall level is decided by all four tests together, and your weakest test sets a floor you have to clear: 267 for B1, 367 for B2.

How long is a TEF IRN certificate valid?

Two years from the date it is issued. Because the level required for naturalisation rose to B2 on 1 January 2026, an older attestation may still be inside its two-year window and yet no longer meet the current threshold.

TEF IRN or TCF IRN: which should I take?

Both are accepted for the same French procedures and both are capped at B2, so neither gives you an advantage on paper. Choose on practical grounds: which one your nearest centre runs, how soon you can get a seat, and which format you have practised. If you have already prepared for the TEF, stay with the TEF.

Can I retake only the test I failed?

No. The four tests have to be sat on the same day for the certificate to be accepted, so a retake means sitting the whole exam again.

Is the TEF IRN the same as TEF Canada?

No. They share a provider and a family of question types, but they are different exams with different purposes. TEF Canada goes up to C2 and is built for IRCC; the TEF IRN stops at B2 and is built for French residence and nationality files. A TEF Canada attestation is not a substitute when a procedure asks for the IRN.
