What is DELF? Levels, Format, Cost and Validity

DELF stands for Diplome d'Etudes en Langue Francaise, an official French language diploma issued by the French Ministry of Education. If you want proof of your French that an employer, a university or an immigration office will accept, this is one of the two documents worth knowing about. The other is TCF, and the difference between them decides which one you should sit.

What DELF is

DELF is a diploma, not a score. You pick one level, sit the exam for that level, and either pass it or you don't. Pass, and you hold a diploma saying you reached that level. It has no expiry date, so a DELF B1 earned in 2019 says exactly what it said the day it was issued.

That permanence is the whole argument for DELF. Score-based tests like TCF and IELTS report where you stood on one particular day, and most institutions stop accepting them after about two years. A DELF diploma is a fact about you that does not lapse while your application sits in a queue.

How DELF and DALF differ

DELF covers A1 through B2. The two levels above it, C1 and C2, belong to a separate diploma called DALF (Diplome Approfondi de Langue Francaise). The two together span the full six-level CEFR scale, and they work the same way: you choose a level, and you pass or fail it.

Almost everyone reading this wants DELF. DALF matters if you are heading for graduate study in French or a job where you will be writing professionally in the language.

How DELF compares with TCF

If you have been researching French exams you have also met TCF, the Test de Connaissance du Francais. They are built for different jobs.

The comparison runs deeper than this table, and the deciding factor is usually who is receiving the result. Our full DELF vs TCF comparison walks through it by goal.

What the exam involves

Every level tests the same four skills in the same order, and the diploma you end up holding is identical in weight whichever route you took to it. What changes is the level you register for, how demanding each paper is, and which version of the exam your circumstances point you to.

What each level certifies

The levels are not just steps on a ladder. Two of them carry specific institutional weight, and that usually decides which one you register for.

A1 is the entry level. You can introduce yourself, ask for directions, order food and fill in a basic form. The exam runs about 1 hour 20 minutes. It proves you have started, which is useful for a visa file or a school record, but no institution requires it.

A2 covers routine transactions: describing your daily life, making a purchase, writing a short message, following a clear announcement. About 1 hour 40 minutes. It is a useful checkpoint on the way to B1 rather than a level institutions ask for.

B1 is the level that changes things. It is the threshold of independence, where you can travel alone in a French-speaking country, hold a conversation on a familiar topic and write a connected text. The exam is about 1 hour 55 minutes.

B2 is the level employers and universities ask for. You can follow complex texts, hold your own with native speakers, and argue a position in writing. The exam runs about 2 hours 30 minutes, and the jump in demand from B1 is larger than the jump from A2 to B1.

If you are choosing between B1 and B2 and the deadline is not urgent, work out what the receiving institution actually asks for before you register. Sitting B2 and failing leaves you with nothing, while sitting B1 and passing leaves you with a diploma you can build on.

How the exam works

Every level tests the same four skills in the same order. Only the difficulty and the clock change.

Scoring is where DELF surprises people. Each skill carries 25 points for a total of 100, and you need 50 to pass. There is a second condition that matters more: you must score at least 5 out of 25 in every skill. One collapsed skill fails the whole exam regardless of your total, so a candidate scoring 73 with 4 in speaking goes home without a diploma while one scoring 53 evenly across the four passes. Our guide to reading a French exam score report works through what that looks like on paper.

Which version you sit

DELF comes in three variants at the same CEFR levels. They differ in subject matter rather than difficulty, and the diploma carries identical weight whichever one you take.

DELF Tout Public is the standard adult version and the one most readers here will sit. Topics range across work, current affairs and social questions.

DELF Junior/Scolaire is for candidates under 18 or enrolled in secondary school. Same level of demand, but the topics are school-appropriate: classes, friends, family, part-time work. It is often cheaper, since student rates are subsidised in many countries.

DELF Pro covers the same A1 to B2 range with workplace subject matter throughout. It suits candidates who need the certificate for employment and would rather discuss a staffing problem than a news article.

What it takes to sit it

The practical side is where timelines go wrong, because the fee, the session calendar and the lead time on registration all have to line up with the deadline you actually need the diploma for.

What it costs

Fees are set by the test centre, not centrally, so they vary by country and rise with the level. B2 costs more than A1 at the same centre.

Treat these as ranges to budget against rather than quotes. Our DELF costs and registration guide covers what the fee includes, what happens if you cancel, and the documents you need on the day.

How long it stays valid

The diploma never expires, which is the practical difference from every score-based alternative. Once you pass, you never sit that level again.

It is accepted for university admission in France, where B2 exempts you from the language test; for French citizenship applications, where B1 is the requirement; for employment with French-speaking employers; and for academic exchange programmes. For immigration to Canada it is the wrong document, because both federal and Quebec programmes name TCF or TEF specifically.

How to register

DELF is administered at authorised test centres worldwide, and you register with the centre directly rather than through a national body. Start at the France Éducation international website to find the one nearest you.

Most centres run four to six sessions a year, typically clustered in January/February, March/April, May/June and October/November. Registration closes four to six weeks before the exam date, so the session you are looking at today may already be shut. Popular sittings go first, particularly May and June, which line up with academic deadlines. You will need valid ID or a passport, a passport-sized photo, and the fee.

Give yourself a realistic run-up. Two to four months of regular study is enough for A1 or A2 from a standing start, B1 usually takes four to six months of focused work, and B2 anywhere from six to twelve depending on where you are starting. Our estimates for how long DELF B2 takes from each starting level break that down by hours rather than months.

How to prepare

Start from the format rather than from French in general. Each level has fixed task types, and knowing what the writing paper will ask means you practise the right thing. Our level-specific writing guides cover what each one demands: DELF A2, DELF B1 and DELF B2.

The trap is uneven preparation. Reading and writing are easy to practise alone, so most candidates arrive strong in those and weak in listening and speaking, which is exactly the shape that trips the 5-out-of-25 rule. Time yourself from the beginning too, because at B1 and B2 the clock is part of the difficulty.

Writing and speaking are the hard skills to self-assess, since you cannot see your own errors. For writing, AI-powered feedback returns corrections and a score on every submission. For speaking, SavoirX runs full DELF mock oral exams at A2, B1 and B2, where an AI examiner interviews you aloud, plays the role-play partner, argues back against your position, and scores you on the official rubric. Our DELF speaking test guide explains each part of the oral.

One more thing worth building in: DELF draws its topics from French and francophone life, so reading French news for a few minutes a day pays off in both the reading paper and the speaking topics.

Frequently Asked Questions

Can I skip DELF levels?

Yes. You can register directly for any level, with no requirement to have passed a lower one first. If you fail, you wait for the next session to try again.

How long before I receive my DELF diploma?

Results are typically available 4-6 weeks after the exam. The physical diploma may take 2-4 months to arrive.

Can I take DELF if French isn't my first language?

Yes. DELF is designed for non-native French speakers, and that is who it is open to.

Is DELF harder than TCF?

They test different things. DELF asks whether you meet every criterion for one level you chose. TCF places you somewhere on the whole scale. Some candidates find the pass/fail pressure harder; others prefer knowing exactly what they are aiming at.

Which DELF level should I take?

The one you can already pass, not the one you hope to reach. Registering above your level costs you the session rather than dropping you a grade, because DELF is pass or fail at the level you entered.
