French language requirements have become one of the most important, and often misunderstood, steps when moving to France. Whether you are applying for a residence permit, a long-term resident card, or planning ahead for French nationality, simply attending French classes is no longer enough.
What now matters is official proof of your French level, obtained through recognised tests or diplomas. This article explains which language tests are accepted, how they work, and what level you will need from 2026 onwards.
Which French Level Do You Need in 2026?
From 1 January 2026, language requirements become standardised and stricter for first-time applications only. The level you must prove depends on the type of residence or nationality application you are filing, and does not apply to renewals.
Required levels from 2026:
First multi-year residence permit (carte de séjour pluriannuelle)
- A2 level + civic exam
- Possible exemption from the language and civic requirements may apply from age 65+, depending on the applicant’s situation and prefectural assessment (not automatic)
First 10-year resident card (carte de résident / long-term EU resident)
- B1 level + civic exam
- Possible exemption from the language and civic requirements may apply from age 65+, subject to individual review by the authorities
French nationality (naturalisation or declaration by marriage)
- B2 level (oral and written)
- No general age-based exemption applies in practice; however, exceptions may be granted in specific cases, notably for medical reasons (such as recognised learning disabilities) or for applicants who can prove the required level through certain French educational qualifications. All exemptions are assessed case by case by the authorities.
These thresholds apply only to applications filed under the 2026 rules and are not applied retroactively.
How Do You Prove Your Language Level?
To meet French immigration and nationality requirements, applicants must provide formal certification of their French level.
Accepted proof includes:
- A recognised French diploma (such as the DELF), or
- A recognised language test, such as:
- TCF IRN
- TEF (particularly for nationality applications)
Simply attending French lessons or providing informal certificates is not sufficient, especially for long-term residence or citizenship.
TCF – Intégration, Résidence et Nationalité (TCF IRN)
The TCF IRN is the most widely used French language test for immigration and residency procedures.
Who Is the TCF IRN For?
The TCF IRN is intended for foreign nationals aged 16 and over who need to prove their level of French for:
- A multi-year residence permit
- A long-term resident card
- A French nationality application
- Validation of A1 level within the OFII integration pathway
The test evaluates language skills only, not history, culture or civics.
Important update: the TCF IRN format evolved from 12 May 2025, as confirmed by France Éducation international. Always prepare using the most recent official materials.
TCF IRN: Test Structure
The test includes four compulsory sections:
- Listening comprehension: 25 multiple-choice questions – 20 minutes
- Reading comprehension: 25 multiple-choice questions – 35 minutes
- Written expression: 3 tasks – 30 minutes
- Oral expression: Face-to-face interview – 10 minutes
Total duration: 1 hour 35 minutes
The test evaluates levels up to B2 on the CEFR scale.
Registering for the TCF IRN
Sessions take place year-round at authorised centres.
You must:
- Contact an approved test centre directly
- Ask about dates, fees, and test format (computer or paper)
- Follow the centre’s registration procedure
You may retake the TCF IRN as often as needed, with a 30-day waiting period between attempts.
Results and Validity
- Results are generally available within 15 working days,
depending on when session materials are received and processed by France Éducation international. - The certificate is issued by the test centre
- Validity: 2 years from the results date
DELF – Diploma in French Language Studies
The DELF (Diplôme d’Études en Langue Française) is an official diploma issued by the French Ministry of Education and is valid for life.
DELF or DALF: Which Should You Choose?
- DELF: A1, A2, B1, B2 (beginner to upper-intermediate)
- DALF: C1 and C2 (advanced levels)
Each diploma is independent, you choose the level you want to sit.
Why Expats Choose the DELF
- Lifetime validity
- International recognition
- Accepted for residency and nationality
- Ideal for long-term settlement planning
What About the TEF?
For French nationality applications, authorities also accept TEF attestations, provided:
- The certificate is less than 2 years old
- The required level (B2 from 2026) is met
This makes the TEF a valid alternative to the TCF for citizenship, depending on the applicant’s situation.
Exemptions and Special Arrangements
Some applicants may qualify for:
- Test adaptations due to disability or medical conditions
- Full exemptions in limited cases
Important points to note:
- Exemptions are not handled by test centres
- Requests must be made directly to the préfecture
- Exemption rules differ between residency and nationality applications
Always consult the relevant Service-Public guidance for your specific procedure.
How Should You Prepare for French Language Tests?
Neither the TCF IRN nor the DELF is based on a fixed syllabus, they assess practical communication ability.
Good preparation includes:
- Studying the exam format and timing
- Practising sample questions
- Reading, listening and speaking French daily
- Managing time carefully during written tasks
Consistent practice matters far more than last-minute revision.
To Wrap It All Up
French language tests are now a core requirement for anyone planning to live long term in France. With clearer thresholds coming into force in 2026, preparation and timing are more important than ever.
Whether you choose the TCF IRN, TEF, or DELF, the right strategy depends on:
- Your visa or permit type
- Your long-term plans in France
- Whether you want short-term proof or lifetime certification
