Quick Answer
DELF (Diplôme d'études en langue française) is an official French-language diploma issued by the French Ministry of Education, covering CEFR levels A1–B2. Each level has four sections (listening, reading, writing, speaking) scored out of 25, with a pass mark of 50/100 and a 5/25 minimum per section. Unlike TCF or TEF results, a DELF diploma is valid for life — which is why it is the preferred proof of French for nationality and long-term residence in France.
What is DELF?
DELF stands for Diplôme d'études en langue française — an official diploma issued by the French Ministry of National Education and administered worldwide by France Éducation international (FEI) through more than a thousand accredited exam centres. It certifies your French at one of four CEFR levels: A1, A2, B1, or B2. The advanced levels C1 and C2 are certified by its sister diploma, DALF.
The single most important property of DELF is that it is a diploma, not a test score. A TCF or TEF attestation expires (typically after two years); a DELF diploma is valid for life. Once you hold DELF B2, you never have to prove B2-level French again — for university admission, for naturalisation, or for any French administrative process that accepts it.
Each level is an independent diploma with no prerequisites. You register directly for the level you need — most adult candidates with a concrete immigration or university goal go straight for B1 or B2.
The four DELF levels
DELF A1 — Discovery
Basic everyday interactions: introducing yourself, simple questions and answers about familiar topics. Rarely required administratively; mostly taken as a first milestone by beginners.
DELF A2 — Survival
Routine tasks and direct exchanges on familiar matters. A2 is the language requirement for the French carte de séjour pluriannuelle (multi-year residence card).
DELF B1 — Threshold
Independent language use: handling travel situations, describing experiences, giving brief reasons and explanations. B1 is the requirement for the 10-year carte de résident.

DELF B2 — Independent
Argued opinions, spontaneous conversation with native speakers, detailed text on a wide range of subjects. B2 is the level French universities require for admission — and from January 2026, the level required for French naturalisation. It is by far the most-taken DELF level.

Exam structure & timing
Every DELF level tests the same four skills — listening (compréhension orale), reading (compréhension écrite), writing (production écrite), and speaking (production orale) — with duration and task complexity scaling up by level. The three written sections run back-to-back in one sitting; the speaking exam is scheduled separately with an examiner.
| Level | Listening | Reading | Writing | Speaking |
|---|---|---|---|---|
| A1 | ~20 min | 30 min | 30 min | 5–7 min (+10 min prep) |
| A2 | ~25 min | 30 min | 45 min | 6–8 min (+10 min prep) |
| B1 | ~25 min | 45 min | 45 min | ~15 min (+10 min prep) |
| B2 | ~30 min | 60 min | 60 min | ~20 min (+30 min prep) |
The production tasks are where levels differ most. At B1 you write a ~160-word personal essay and hold a structured conversation with a role-play; at B2 you write a ~250-word formal argumentative text (letter, article, or contribution to a debate) and defend an opinion drawn from a short source document in front of the examiner, including a debate phase where the examiner challenges your position.
Scoring & pass marks
DELF scoring is refreshingly simple compared to CLB-mapped tests:
- Each of the four sections is scored out of 25 points — total 100.
- You pass with 50/100 overall.
- There is an elimination threshold: below 5/25 in any single section fails the whole exam, regardless of your total.
The practical consequence: a lopsided profile is dangerous. Candidates who are strong readers but avoid speaking practice fail on the 5/25 rule far more often than on the 50-point total. Balanced preparation across all four skills — with extra weight on your weakest production skill — is the highest-percentage strategy.
Results are typically published a few weeks after the session, and the physical diploma follows a few months later. An attestation issued with your results is accepted by préfectures and universities while you wait for the diploma itself.
DELF for French nationality & residence
France's 2024 immigration law raised the language bar at every stage of the residence-to-citizenship ladder, effective January 1, 2026. DELF maps onto it directly:
| Application | Required level | DELF diploma |
|---|---|---|
| Carte de séjour pluriannuelle (multi-year card) | A2 | DELF A2 |
| Carte de résident (10-year card) | B1 | DELF B1 |
| Naturalisation (French citizenship) | B2 | DELF B2 |
TCF and TEF results are also accepted at each stage, but their limited validity means a delayed application can force a retest. A DELF diploma taken once covers the requirement forever — which is why most advisers recommend DELF when your timeline is longer than a year or uncertain.

DELF vs TEF vs TCF
The three exams serve overlapping but distinct purposes. The short version: DELF for France and for life, TEF/TCF Canada for Canadian immigration, and TCF/TEF (France versions) when you need a fast result for a French deadline.
| Feature | DELF/DALF | TCF / TEF |
|---|---|---|
| Type | Diploma (pass/fail at a chosen level) | Level test (places you on a scale) |
| Validity | Lifetime | ~2 years |
| Risk | Fail if below the level | No fail — you get whatever level you show |
| Best for | France (nationality, residence, university), permanent proof | Canada immigration (TEF/TCF Canada), tight French deadlines |

How to prepare
DELF results are decided in the production sections. Listening and reading are trainable with volume; writing and speaking need methodology plus feedback, because the examiner grades structure, register, and argumentation — not just correct French.
- Learn the task formats first.Every DELF writing and speaking task has a known shape (formal letter, opinion essay, document-based exposé). Candidates who walk in knowing the expected structure start with a scoring advantage that vocabulary alone can't buy.
- Practice production with feedback loops. Write and speak on exam-style prompts, get scored feedback, fix your three most frequent errors, repeat. PrepMyFrench's AI speaking practice and AI writing evaluation both support DELF (A1–B2) task formats.
- Respect the 5/25 rule. Spend disproportionate time on your weakest skill — that section is the one that can fail you.
- Simulate the real timing.B2's 60-minute argumentative essay and 30-minute speaking prep reward candidates who have rehearsed under the clock.

Frequently asked questions
What is the DELF exam?
DELF (Diplôme d'études en langue française) is an official French-language diploma issued by the French Ministry of Education and administered by France Éducation international. It certifies CEFR levels A1, A2, B1, and B2, and unlike test-based certificates (TCF, TEF), the DELF diploma is valid for life.
Is the DELF diploma valid for life?
Yes. DELF is a diploma, not a test attestation, so it never expires. This is its biggest advantage over TCF and TEF results, which are typically valid for two years. If you need proof of French for a long-term goal such as French nationality, DELF avoids retesting.
What is the DELF pass mark?
Each DELF level is scored out of 100, with four sections (listening, reading, writing, speaking) worth 25 points each. To pass you need at least 50/100 overall AND at least 5/25 in every section. A very strong performance in three sections cannot compensate for a section below 5.
Which DELF level do I need for French nationality?
Under the 2024 French immigration law, naturalisation applications require B2-level French from January 1, 2026 (previously B1). A DELF B2 diploma satisfies this permanently. For the 10-year carte de résident the requirement is B1, and for the multi-year carte de séjour pluriannuelle it is A2.
What is the difference between DELF and DALF?
DELF covers CEFR levels A1 to B2; DALF (Diplôme approfondi de langue française) covers C1 and C2. Both are issued by the French Ministry of Education, both are valid for life, and both are administered by France Éducation international through the same network of exam centres.
DELF or TEF/TCF — which should I take for France?
For French residence and nationality, all three are accepted, but DELF/DALF diplomas never expire while TEF and TCF attestations are time-limited. If your application is more than a year away, or you may need the proof again later, DELF is usually the better investment. TCF/TEF suit tight deadlines because sessions run more frequently and results arrive faster.
How long does it take to prepare for DELF B2?
From a solid B1, most candidates need 2–4 months of regular practice to pass DELF B2. The production sections (writing and speaking) decide most results — the argumentative essay and the structured oral defense both require trained methodology, not just vocabulary.
Can I skip levels and go straight to DELF B2?
Yes. DELF levels are independent diplomas — there are no prerequisites. You can register directly for the level you need (for example B2 for naturalisation) without ever taking A1, A2, or B1.
