TCF IRN for French Nationality: Format, Level & Booking
How TCF IRN works for French naturalisation and residence: modules, B2 expectations, validity, and how it compares with DELF B2.
Quick Answer
TCF IRN (Intégration, Résidence et Nationalité) is a French-administration-oriented TCF session used for residence and nationality files. For naturalisation, candidates typically need a B2-level result on the required modules. Certificates are usually valid for two years, so time your exam to your prefecture appointment.
What TCF IRN is for
TCF IRN is designed for people proving French for integration, multi-year residence, resident cards, and nationality — not for Canadian immigration (that is TCF Canada).
Always book the IRN / nationality-compatible session type your center lists for prefecture files. A general TCF or TCF Canada score is not interchangeable.
Format candidates should expect
TCF IRN focuses on the skills the French administration cares about for everyday integration and civic life: listening and speaking are critical; reading and writing requirements depend on the exact session and purpose.
Practice short, clear oral answers about daily life, work, and civic topics. Examiners reward intelligibility and structure more than literary French.
- Confirm the exact modules your prefecture requires.
- Target B2 if naturalisation is the goal.
- Expect a two-year validity window on the certificate.
- Book early in busy cities like Paris and Lyon.
TCF IRN vs DELF B2
DELF B2 never expires and is ideal if your nationality process may drag. TCF IRN is often faster to schedule and score when you have a fixed appointment soon. Many candidates choose based on timeline, not difficulty.

Frequently asked questions
Is TCF IRN accepted for French naturalisation?
Yes, when you reach the required level on the accepted IRN/nationality session. Confirm the current prefecture list of accepted tests before paying for a seat.
How long is a TCF IRN result valid?
Typically two years. If your nationality appointment is delayed, the certificate can expire and you may need to retest — which is why some candidates prefer DELF B2.
Can I use TCF Canada for French nationality?
No. TCF Canada is for Canadian immigration pathways. France residence and nationality require the France-facing session types (TCF IRN / TCF ANF-style) or an accepted diploma such as DELF.
