Your naturalization file is due in four or five months and you still have to sit the TCF IRN. You want a concrete plan, week by week, that takes you to B2 (the threshold required since January 1, 2026) without drowning you in dozens of resources.
Here is a 3-month preparation plan that actually works, built from the official test format published by France Éducation International and the experience of teachers of French as a foreign language. No theory, just what you need to do to reach B2 and walk into the test without panicking.
The TCF IRN (Test de Connaissance du Français pour l'Intégration, la Résidence et la Naturalisation) is the reference test for French naturalization. It runs 1h35 (95 minutes) exactly and covers four language skills: listening (25 multiple-choice questions, 20 min), reading (25 multiple-choice questions, 35 min), writing (3 exercises, 30 min), and speaking (3 face-to-face tasks with an examiner, 10 min). To reach the B2 level in speaking and writing required since 2026, plan on 3 months of intensive preparation if you start at B1, or 6 to 12 months if you start at A2. Note: since 2026, naturalization also requires a separate civic exam (multiple-choice questions on the values, history, and institutions of the French Republic). Do not confuse it with the TCF IRN, which only assesses language skills.
Before you start - where you really stand
Before throwing yourself into three months of prep, take an honest placement test. The trap is overestimating your level. Many candidates assume they are B2 because they can hold a basic conversation, when they are actually B1.
Quick test: pick a video of a French journalist speaking at normal speed (France Info, BFM, France 24). No subtitles. If you follow 90% of what they say and can summarize it in five French sentences, you are likely B2. If you miss 30 to 40% of the content, you are B1. If you miss more than half, you are A2 or below.
Adjust your plan accordingly. What follows is calibrated for a B1 learner aiming at B2 in three months.
The actual TCF IRN format (know it cold)
Before you start grinding, you need to know exactly what you are preparing for. The test runs 1h35 in total and includes four mandatory parts:
- Listening - 20 min, 25 multiple-choice questions. You hear short audio extracts (announcements, dialogues, everyday exchanges) and tick the right answer out of four options.
- Reading - 35 min, 25 multiple-choice questions. You read short documents (signs, emails, articles, forms) and answer multiple-choice questions.
- Writing - 30 min, 3 exercises. Three short tasks (roughly 30 to 90 words each): a simple message, a narrative or description, and a short opinion piece.
- Speaking - 10 min, 3 tasks face-to-face with an examiner. Guided interview (about 3 min), interaction exercise (about 3.5 min), expressing a point of view (about 3.5 min). It is an oral exam. There is no written composition in this part.

Month 1 - building the reflexes
Weeks 1-2: listening at the real test format
The classic mistake is to stick with slowed-down classroom audio. The TCF IRN uses excerpts at full speed with a range of accents. Train your ear on that format from day one.
- Every day: 20 minutes of a French podcast for intermediate learners (RFI Journal en français facile, Coffee Break French intermediate level).
- Three times a week: one YouTube video in French at full speed, on a topic you actually care about. Watch it twice: first for the gist, then for the details.
- Targeted tool: 360 French Immersion by HelloFrench offers 60 authentic dialogues between native speakers with a word-by-word karaoke mode. It trains your ear on spoken French without leaving you stuck on words you do not catch. A solid fix for the gap most learners have with full-speed listening.
Weeks 3-4: reading comprehension
- Every day: one article from the simplified French press (RFI Savoirs, 1jour1actu for the basics, or Le Monde "En clair").
- Twice a week: one full article from Le Monde, Libération, or Le Figaro. Note unknown words, translate them, write your own sentences with them.
- Targeted vocabulary for the TCF IRN: daily life, work, health, school, administrative procedures, citizenship, environment.
Month 2 - speaking and writing
Weeks 5-6: speaking
This is the hardest part for most candidates. The speaking section runs 10 minutes face-to-face with an examiner, not in front of a computer. Three tasks: a guided interview about your life, an interactive exchange (for instance, getting information), and expressing an argued point of view.
- Tandem practice: find a French-speaking partner (italki, Tandem, HelloTalk) for two 30-minute sessions per week.
- Pronunciation scoring: use a tool that grades your pronunciation word by word. 360 French Immersion includes one (trained to listen like a French ear), so you can self-correct without needing a teacher for every drill.
- Typical topics: practice speaking for two or three minutes with no prep on prompts like "My hobbies," "My journey in France," "Why I am learning French," "A typical day."
Weeks 7-8: writing
- Three texts a week of 30 to 90 words (the actual format of the three TCF IRN writing tasks). Have them corrected by a teacher or an online proofreader.
- TCF IRN format: short message (to a neighbor, to a service), a narrative or description (recounting an event), a short opinion piece (your view on a simple social topic).
- Errors to hunt: past participle agreement, subjunctive conjugation, prepositions (à/de), adjective-noun agreement.
Month 3 - simulation and finishing touches
Weeks 9-10: TCF IRN simulation
- Buy a TCF IRN prep book (the "Réussir le TCF" series for example) with audio and answer keys.
- Run two full mock tests per week under real conditions: timer on, no breaks, no going back.
- Review your mistakes after each mock. Which skills are below the threshold? Prioritize those.
Weeks 11-12: polish and confidence
- Drop to one mock test a week so you do not burn out.
- Civic exam: prepare it in parallel, but separately. Since 2026, naturalization also requires a civic exam (40 multiple-choice questions, minimum 32 correct) on the history, values, and institutions of the French Republic. This is NOT in the TCF IRN. It is a separate test, and revising for it is a different exercise.
- Rest and confidence: in the last three days, only do light review. Your ear needs rest to perform on test day.
Test day - 5 practical tips
- Arrive 30 minutes early. The center checks your ID, you wait, and that whole process is stressful if you are running late.
- Bring water and a snack. The test runs 1h35, but with check-in, setup, and the individual speaking section, you are easily on site for 2h30 to 3h.
- Listening: never freeze on a single question. If you are torn between two answers, pick on instinct and move on.
- Speaking: talk clearly and slowly. The examiner prefers a steady, structured pace over a fast delivery packed with mistakes.
- Writing: keep five minutes at the end to reread and fix agreement and conjugation slips.
What it costs in total
- TCF IRN registration: roughly 110 to 165 USD (100 to 150 EUR) depending on the center (Alliance française, France Éducation International, accredited bodies). France Éducation International does not publish a single official rate, so check directly with the center where you register.
- Prep book: 28 to 45 USD (25 to 40 EUR).
- Tandem sessions: often free, or 11 to 28 USD (10 to 25 EUR) per hour for a private tutor.
- Structured immersive method: 99 to 275 USD (89 to 249 EUR) for tools like 360 French Immersion (lifetime access, no subscription).
Realistic total budget: 275 to 660 USD (250 to 600 EUR) for three serious months of prep. Far cheaper than a language-school course (1,650 to 3,850 USD / 1,500 to 3,500 EUR for the same outcome).

NB: This article reflects the TCF IRN format published by France Éducation International and the naturalization reform that came into force on January 1, 2026. That reform raised the language threshold from B1 to B2 and introduced a separate civic exam (multiple-choice questions on values, history, and institutions). The TCF IRN only assesses language skills, not civic knowledge. Always cross-check service-public.fr before you register for the latest version of the requirements.
