Introduction

Living in France is no longer enough to prove that you speak French. Since the 2020 decree on naturalization, and more broadly for enrolling in a master's program, entering an engineering school, accessing certain public jobs, or simply validating your language skills with an employer, the administration and universities require an official diploma: DELF, DALF, TCF, TEF.

For a foreigner who already speaks the language well, it is often just a formality. For those who have learned on the job, or who need to advance a level to obtain naturalization B1 or a master's B2, preparing for the certification deserves serious attention. This guide details in 2026 the different diplomas, their costs, where to register in France, and effective free resources, with examples of Chinese, Moroccans, Algerians, Vietnamese, Senegalese, and Brazilians who have recently taken the exam.

DELF, DALF, TCF, TEF: Who Does What?

The ecosystem can seem confusing. Four certifications coexist, all issued under the authority of France Éducation International (formerly CIEP, the public reference organization based in Sèvres):

• DELF (Diploma in French Language Studies): A1, A2, B1, B2. Single-choice level exam, valid for life. Four tests: listening comprehension, reading comprehension, written production, oral production.
• DALF (Advanced Diploma in French Language): C1, C2. Same format as DELF, but at a more demanding level. Valid for life.
• TCF (Test of Knowledge of French): a global test that positions you on the A1-C2 scale based on your score. Valid for 2 years only. Several versions: TCF for the general public, TCF Canada, TCF ANF (access to French nationality), TCF Quebec.
• TEF (Test of French Evaluation): equivalent to TCF but issued by the Chamber of Commerce and Industry of Paris. Several versions: TEF Canada, TEFAQ, TEF Naturalization.

In a nutshell: DELF/DALF = diploma valid for life for a specific level. TCF/TEF = quick test that positions, valid for 2 years, ideal when only one proof is needed.

Which Diploma to Take for Which Objective?

This is the question everyone is asking. Practical answer:

• French naturalization (by decree or marriage) → B1 minimum. DELF B1, TCF ANF, TEF Naturalization, TEF B1+ all accepted. The TCF ANF is the most practical: one exam day, results in 4 to 6 weeks, ~ 100 € (approved Alliance Française centers).
• Enrollment in a master's program at a French university → B2. DELF B2, or TCF score 400+ (out of 699). Some universities accept a B1 for English-taught programs.
• Engineering school, business school, doctorate → B2 or C1. DELF B2 minimum, DALF C1 strongly recommended for selective exams.
• French public service (category A exams) → C1. DALF C1 required for most external competitions.
• Professional validation / proof to the employer → B1 or B2. Choose: DELF (lifetime diploma, reassuring) or TCF (quick).
• Long-stay visa Canada / Quebec → TEF or TCF Canada, not DELF (Quebec only recognizes TEF/TCF).

Wei, a Chinese engineer, took the DELF B2 (175 €) in Paris in two months to enroll in a master's program. Karim, a Moroccan, chose the TCF ANF (100 €) in Bordeaux because he was aiming for naturalization. Hoang, a Vietnamese doctoral student, took the DALF C1 (240 €) to secure a position as a lecturer.

Levels: What Do B1, B2, C1 Mean in Practice?

The Common European Framework of Reference for Languages (CEFR) defines six levels from A1 to C2. To place yourself:

• A1 (discovery): introduce yourself, state your name, age, read simple signs. Enough for a long tourist visa.
• A2 (elementary): hold a simple conversation, recount your day, understand a recipe. Level required for the residence permit since 2018.
• B1 (independent user): understand the essentials of a news broadcast, write a cover letter, express your opinions. Level required for naturalization.
• B2 (advanced): follow a university course, debate, write an argumentative text. Level required to enter a master's program.
• C1 (proficient): nuanced writing style, understand long and complex texts, argue. Level required for public service.
• C2 (mastery): nearly native equivalent. Useful for interpreters, translators, French teachers.

On Exam Day: Typical Procedure

The exam lasts a full day for DELF/DALF:

• Listening comprehension: 30 to 40 minutes, listening to 2 to 3 audio documents followed by multiple-choice questions.
• Reading comprehension: 30 to 50 minutes, reading 2 to 3 texts followed by questions.
• Written production: 45 to 60 minutes, writing a text (letter, article, essay depending on the level).
• Oral production: individual presentation of 10 to 25 minutes after preparation, in front of a jury of 2 examiners. Often in the afternoon or on another day.

For the TCF, everything is grouped into half a day, often in computerized multiple-choice format for comprehension, plus a short written and oral production.

Note to pass: 50/100 minimum overall + at least 5/25 per test for DELF. The TCF does not have a "pass/fail" score: it positions you on the scale.

FAQ

TCF or DELF B1 for naturalization: which one to choose?

The TCF ANF is faster (one day, results in 4 to 6 weeks, ~ 100 €) but the score is valid for 2 years only. The DELF B1 takes longer to pass (preparation, rarer sessions, results in 8 weeks, ~ 145 €) but is valid for life. If you plan to naturalize within 2 years, take the TCF ANF. If you attempt it later, or want to reuse it for a master's, take the DELF B1.

Does my child enrolled in France need the DELF to go to a master's?

No. A French baccalaureate or any French diploma at the baccalaureate level or higher exempts from DELF/DALF for university enrollment. It is the French schooling that serves as proof. The same applies for naturalization: a brevet, CAP, or baccalaureate is sufficient for the B1 criterion.

What happens if I fail the exam?

For DELF/DALF: you can retake it in the next session (usually 2 to 3 months later) by paying the fees again. There is no limit to the number of attempts. For the TCF: you receive a score, which positions you; if the score is too low for your goal, you retake it after at least 30 days.

Can you take DELF and DALF at the same time?

Yes, but it is generally not useful. If you are at level C1, go directly for the DALF C1. The DELF B2 is redundant. Exception: some scholarships or schools explicitly require a DELF B2; read the regulations beforehand.

How much preparation time is usually needed?

To pass one level above your current level: 3 to 6 months of regular effort (5-10 hours/week). To pass the level you already master: 4 to 8 weeks to get used to the exam format and typical traps (timing, structure of the formal letter, etc.).
