The short answer
DELF and DALF are diplomas: you choose a level, pass it, and keep it for life. The TCF and TEF are tests: you sit one exam, receive a score converted into a CEFR level, and it expires after two years. Choose by goal rather than by test date. French universities generally ask for DELF B2, Canadian immigration accepts TEF Canada or TCF Canada, and French nationality now requires proof of B2.
If you've started looking into French certification, you've probably run into a wall of acronyms: DELF, DALF, TCF, TEF, and sometimes TCF Canada, TCF Québec, or TCF ANF thrown in for good measure. Almost every student asks me the same question at some point: "which one do I actually need?"
The honest answer is: it depends entirely on your goal. A French exam for studying in Paris is not the same exam you want for Canadian immigration, and using the wrong one can cost you months of preparation and, in some cases, real money. Here's exactly how these exams differ, and how to pick the right one.
These aren't niche exams either: the TCF alone drew more than 219,000 candidates in a single record year, sitting across 763 accredited centres worldwide. In my own teaching, I've had students book the wrong one of these three by accident, then have to redo months of prep once they realised their target institution didn't accept it, which is exactly the mistake this guide is meant to save you from.
A note before we start
Exam formats and immigration requirements change from time to time, and different countries or institutions may ask for a specific version of a specific exam. Always confirm the exact requirement with the official body asking for it (a university, IRCC for Canada, or your local préfecture for French citizenship) before registering. This guide gives you the general landscape so you know what questions to ask.
The three exams, in one sentence each
- DELF / DALF is a diploma, split into 6 independent levels (A1 to C2), that you keep for life once you pass it.
- TCF (Test de Connaissance du Français) is a placement-style test that gives you a score and a corresponding level, valid for 2 years, with several versions for different purposes.
- TEF (Test d'Évaluation de Français) is very similar in spirit to the TCF, run by a different organisation, mostly known for its role in Canadian immigration.
DELF and DALF: the permanent diploma
DELF (Diplôme d'Études en Langue Française) and DALF (Diplôme Approfondi de Langue Française) are official diplomas issued by the French Ministry of Education, through France Éducation international. They're split into 6 independent diplomas that match the CEFR scale: DELF A1, A2, B1, B2, then DALF C1, C2.
You choose the level you want to sit, and you're tested on all four skills: listening, reading, writing, and speaking, each scored out of 25. You need 50/100 overall and a minimum of 5/25 in each skill to pass.
The biggest difference from the other two exams: a DELF or DALF diploma never expires. Once you have it, it's yours permanently, which makes it the standard choice for university admission in France and for anyone who wants a certificate that won't need renewing. If DELF is your target, see our DELF exam preparation tips for how to maximise your score.
TCF: the flexible, multi-purpose test
The TCF is not a diploma, it's a standardised test. Instead of choosing a level in advance, you sit one exam and receive a score that's then converted into a CEFR level from A1 to C2, along with an official attestation. This score is valid for 2 years from the test date.
What makes the TCF confusing is that it comes in several versions, each built for a specific purpose:
| Version | Typically used for |
|---|---|
| TCF Tout Public | General personal or professional certification, no specific institutional requirement |
| TCF Canada | Canadian permanent residence applications (e.g. Express Entry), where French proficiency can add points |
| TCF Québec | Quebec-specific immigration procedures |
| TCF ANF | Applying for French nationality (naturalisation), as an alternative to a DELF diploma. Since 1 January 2026 the level to reach is B2, in speaking and writing, so you need a B2 result rather than the B1 that was enough until the end of 2025 (see the new B2 rules) |
The core content (listening and reading comprehension) is similar across versions, but which sections are mandatory, and the exact scoring, can differ depending on the version and what the requesting institution asks for. Always double-check you're registering for the specific version that matches your goal, not just "the TCF."
TEF: the other major test, and the face of TEF Canada
The TEF (Test d'Évaluation de Français) is administered by the Paris Île-de-France Chamber of Commerce and Industry, which has run it since 1998, a separate organisation from the one behind DELF/DALF/TCF. Structurally, it plays a similar role to the TCF: you get a score converted into a CEFR level, valid for 2 years, across the same four skills (listening, reading, speaking, writing).
The TEF is best known through TEF Canada, historically one of the two accepted French tests (alongside TCF Canada) for Canadian immigration programs like Express Entry, where a strong French score can add significant Comprehensive Ranking System points, even for applicants whose first official language is English.
Because TCF and TEF serve such similar purposes for Canadian immigration, which one is currently accepted, and for which specific program, is exactly the kind of detail worth confirming directly on the IRCC (Immigration, Refugees and Citizenship Canada) website before you book a test date.
Side-by-side comparison
| DELF / DALF | TCF | TEF | |
|---|---|---|---|
| Format | Diploma, one level at a time | Test, scored then levelled | Test, scored then levelled |
| Validity | Lifetime, never expires | 2 years | 2 years |
| Administered by | France Éducation international | France Éducation international | Paris Île-de-France CCI |
| Most common use | University admission, permanent certification | Canada/Quebec immigration, French citizenship | Canada immigration (TEF Canada) |
Whichever you pick, the next question is which level to register for, and paying to sit one band too high is an expensive way to find out. Our free French level test gives you an A1 to B2 estimate in about six minutes, and explains every question you get wrong.
So which one should you take?
Rather than picking an exam first, start from your goal:
- Applying to a French university? Most institutions ask for DELF B2, sometimes DALF C1 for graduate programs. Some accept a TCF score instead, so check the specific requirement on the university's admissions page.
- Applying for French citizenship? Since 1 January 2026 you'll need to demonstrate a B2 level, in both oral and written French, following décret n° 2025-648 of 15 July 2025, which replaced the previous B1 oral requirement. A DELF B2 diploma or a TCF ANF result at B2 both work, and a separate civic knowledge exam became compulsory on the same date. I've set out the full picture in French citizenship in 2026 and the B2 requirement, and it's still worth confirming the accepted list with your préfecture.
- Immigrating to Canada or Quebec? This is the territory of TCF Canada / TCF Québec and TEF Canada. Since a strong French score can meaningfully boost an Express Entry application, check IRCC's current list of accepted tests before registering, and pick whichever test has a testing centre and date that actually works for your timeline.
- Just want a recognised certificate for your CV or personal record? DELF/DALF is usually the better pick, precisely because it never expires: you sit it once and it's valid forever, unlike the 2-year window on TCF and TEF scores.
A common mistake: picking the exam before the goal
The single most expensive mistake students make is booking whichever exam their friend took, or whichever one has the nearest test date, without checking that it's actually the one their target institution accepts. A DELF B2 diploma is a fantastic credential, but it won't help a Canadian Express Entry application the way a TCF Canada or TEF Canada score will. Always start from the requirement on the other end (the university, the immigration program, the préfecture), find the exact exam and level or score threshold they ask for, and only then start preparing.
How the exams are structured, in practice
Despite their different purposes, all three exams test the same four skills, just packaged differently:
Compréhension orale (listening) → multiple choice, based on audio recordings
Compréhension écrite (reading) → multiple choice or short answers, based on written texts
Expression écrite (writing) → producing a written text: an email, an essay, an opinion piece
Expression orale (speaking) → a face-to-face or recorded interview, defending a point of view
The speaking and writing sections are almost always the hardest to prepare for alone, because unlike listening and reading, there's no multiple-choice safety net: you need a method, useful connectors, and enough practice to structure an answer under time pressure. That is most of what we do in DELF and DALF preparation lessons: full answers, timed, then corrected together.
How to actually prepare
Whichever exam you're sitting, preparation comes down to the same three things: knowing the exact format inside out, having a reliable method for the speaking and writing tasks, and practising under real exam conditions before the day itself. Reading about the format once is not enough, you need to have produced full timed answers, ideally with corrections, so you know exactly where you're losing points. If doing that alone is the part that never quite happens, that is exactly what exam preparation lessons are for.
