DELF vs TCF: which French test should you take?

The single most important thing to know about DELF vs TCF is that they are not substitutes for each other. They serve different institutional purposes. Choosing the wrong one means doing the test twice. The right choice depends entirely on what you need the certificate for.

What each test actually is

DELF (Diplome d'Etudes en Langue Francaise) is a permanent diploma issued by France Education international on behalf of the French Ministry of Education. You pass a specific level (A1, A2, B1, or B2) and hold that diploma for life. There is no expiry date. The DELF covers four sections: listening, reading, writing, and speaking, each scored out of 25. You need 50/100 to pass, with a minimum of 5/25 in every section.

TCF (Test de Connaissance du Francais) is a French-language proficiency test issued by France Education international (the same body) but designed as an assessment tool rather than a diploma. It gives you a score on the CEFR scale. The standard TCF result is valid for two years, after which it expires and you need to re-test if you still need documentation.

There is also the TEF (Test d'Evaluation de Francais), a separate product from the Paris Chamber of Commerce, which functions similarly to the TCF in the immigration context.

Why your goal determines the answer

Canada federal immigration: TCF or TEF

If you are applying to Canada through Express Entry, the Provincial Nominee Program (PNP), or other federal immigration streams, Immigration, Refugees and Citizenship Canada (IRCC) accepts two French-language tests: TCF Canada and TEF Canada. The DELF is not accepted for federal immigration to Canada.

This is the clearest case. If Canada federal immigration is your goal, you need TCF Canada or TEF Canada. Not DELF.

Quebec immigration: DELF

Quebec runs its own immigration programs (including the Programme de l'experience quebecoise). Quebec requires a permanent language diploma, not a timed test. This means DELF (or DALF for C1/C2). The TCF is not accepted for Quebec immigration programs in the same way.

If you are targeting Quebec specifically, DELF is the right product.

French university admission: DELF B2

French universities typically require B2 to admit international students to degree programs taught in French. The DELF B2 is widely accepted. The TCF result at an equivalent level may also be accepted by some institutions, but the DELF is the standard expectation. Check the specific institution's requirements.

French naturalisation: DELF B2

From January 1, 2026, French naturalisation requires B2 in both oral and written French under Decree no. 2025-648 of July 15, 2025. The DELF B2 is one of the accepted proofs. TCF results at an equivalent level are also accepted in this context, but the two-year validity means timing matters if your application takes longer.

DELF is the permanent record. TCF is the timed snapshot. If the process you are applying to takes more than two years from test date to decision, TCF validity becomes a real risk.

The format differences

Beyond the institutional use case, the tests differ in how you sit them.

DELF assesses one specific level at a time. You register for DELF B2, and all four sections are calibrated to B2. The result is either pass or fail at that level.

TCF is a single adaptive-style test that places you on a scale. You take it once and receive a score pointing to your CEFR level. Some versions (like TCF Canada) include optional written and spoken production components.

This means DELF preparation is level-specific: you study the B2 task types, the B2 rubric, the B2 timing. TCF preparation is more about overall proficiency at whatever level you are at.

The validity difference matters in practice

TCF results expire after two years. If your immigration or visa application takes longer, or if you are building toward a goal that is a year or two away, you may end up re-testing. This is a real cost in time and money.

DELF has no expiry. A DELF B2 you earned in 2020 is still valid in 2030. For any goal that involves a long timeline, the permanent diploma is more reliable documentation.

Study hours: the same effort applies

Whether you are preparing for TCF or DELF, the French skills you need are roughly the same at a given CEFR level. CEFR ballpark hours from scratch: A1 around 80-100 hours, A2 around 150-200 hours, B1 around 350-400 hours, B2 around 500-600 hours. These estimates do not change based on which test you sit. What changes is the task format you practice for.

Frequently asked questions

Can I use DELF for Canada federal immigration?

No. IRCC only accepts TCF Canada and TEF Canada for French-language requirements in federal immigration streams. DELF is not on the accepted list.

Is TCF harder than DELF?

They measure different things in different ways. TCF is an adaptive test that places you on a scale. DELF tests a specific level with specific task types. Most people find that preparation for one does not fully transfer to the other because the task formats are different.

What if I need the result for both Canada federal immigration and Quebec immigration?

You would need both TCF Canada (for federal) and DELF (for Quebec). They are not interchangeable. Some candidates take both if they are keeping multiple paths open.

Do TCF and TEF measure the same thing?

Both are French-language proficiency tests accepted for Canada immigration, and both give results on the CEFR scale. TEF is issued by the Paris Chamber of Commerce; TCF is issued by France Education international. For immigration purposes they are functionally equivalent, but check the specific immigration stream to confirm which one is accepted.
