When do you need to register for the DELF?

Switzerland's five 2027 DELF sessions close registration 43 to 71 days before the paper: six to ten weeks.

The five 2027 DELF sessions in Switzerland close registration between 43 and 71 days before the written papers, according to the calendar published on 21 April 2026. The gap is our own count from the printed dates. In other words, signing up for the DELF is decided six to ten weeks ahead, and at one specific centre.

When do DELF registrations actually close?

The date that matters is not the exam date, it is the registration deadline. The 2027 examination calendar for Switzerland, a document dated 21 April 2026, prints one date for the group papers and one registration deadline for each of its five sessions:

March: papers on Saturday 20 March 2027, registration until Friday 8 January 2027
May: papers on Saturday 22 May 2027, registration until Friday 12 March 2027
June: papers on Saturday 19 June 2027, registration until Friday 9 April 2027
September: papers on Saturday 18 September 2027, registration until Friday 6 August 2027
November: papers on Saturday 13 November 2027, registration until Friday 10 September 2027

Counting the days, and the count is ours since the document only gives dates, the gap runs from 43 days in September to 71 days in March, May and June, with 64 days in November. Six to ten weeks. Anyone deciding in April to take the DELF in spring has already missed the May session, even though the exam itself has not happened yet.

If you are reading this from the UK, Ireland, the United States, Canada or Australia, the sessions near you are run by an Alliance Française, an Institut français, a university or a partner school, and each of them announces its own dates. Nothing about the Swiss figures transfers to your city except the order of magnitude: expect the deadline to fall weeks, not days, before the paper.

Who sets the dates: the centre, the country or a ministry?

Three levels of decision coexist, which is exactly why a single answer is so hard to find online.

In France, some sessions are fixed by an official text. The note de service of 14 April 2026, published in the Bulletin officiel no. 19 of 7 May 2026, sets the 2027 dates for the DILF (9 March, 8 June, 7 September and 1 December) and for the DELF taken in schools at A1, A2 and B1 (Tuesday 11 May and Thursday 3 June 2027). The DILF dates are described there as common to all examination centres, while running the school DELF falls to the regional education authorities. Yet the text says nothing at all about registration or any deadline: an act that fixes dates does not tell you how to enter.

In Switzerland, a single national calendar applies to every centre, and the document names thirteen of them, from Aarau to Lugano, including Geneva, Lausanne, Neuchâtel, Sierre, Bern, Zurich and St Gallen.

Elsewhere the centre itself opens and closes a registration window. The Institut français in Cyprus advertises a registration period from 15 January to 12 March 2026 for its May 2026 session, without publishing an exam date at all.

So the only authority that concerns you is the approved centre where you will sit the exam. A calendar from another country gives you the size of the delay, not your date.

How many sessions a year can you count on?

The Swiss calendar lists five for 2027, and they do not all offer the same thing: DELF A1 to B2 for adults and juniors, DELF A1.1 and A1 Prim for children, DALF C1 and C2. Oral papers do not fall on the written day either: the document gives a window, for instance 1 to 31 March 2027, with C2 as the exception on a fixed Friday, 19 March 2027.

Five sessions a year is not a world standard, and plenty of centres hold two or three. Hence the real price of a missed deadline: not a week, but two to four months of waiting. It is also why the level is chosen before you register rather than after. The level is written on the form and does not change the night before, neither upwards because you have improved nor downwards because the B1 format now looks out of reach. Aiming at a first exam at A2 or aiming at B1 is the same piece of paperwork and not the same year of work.

How do you avoid missing the deadline?

Three moves, in this order:

find the approved centre nearest you, depending on the country an Institut français, an Alliance Française, a university or a partner school, then write down two dates and not one: the paper and the cut-off
if no deadline is published, take ten weeks as your working assumption, email the centre to confirm it, and start assembling your documents without waiting for the reply
settle the level before you fill in the form, with a level test and a look at what the target paper actually asks, for instance the method for B2 or the four papers of C1

Registration itself usually means an identity document and a payment, but the exact list of documents and the payment method belong to the centre: it is the centre you ask, and finding it early beats hunting for a worldwide calendar that does not exist.

What these dates do not tell you

The 43 to 71 days describe one country and one year, not the DELF in general. The figure comes from a single document, and the gap in days is our arithmetic on the printed dates, not a published statistic.

Three caveats. The deadline is printed once per session, after the block of exam dates, and which diploma it attaches to is inferred from its position: for one specific diploma, have it confirmed. The document itself carries the words "sous réserve de toute modification", subject to change, and some Prim dates are still "à déterminer", to be determined. Finally, an official text that fixes national dates may say nothing about how to register, and a centre's own page sometimes shows neither an exam date nor a deadline, only a link to a form.

Hence a three-step decision rule. First, put the deadline in your calendar rather than the exam date, because the deadline is the real due date. Second, count ten weeks back from the session you want, and treat that result as an estimate to be checked. Third, have both dates confirmed in writing by your centre before you pay anything.

A deadline you can check on your own, in a few minutes. Which level to enter for, much less so: that is decided in front of someone who hears you speak and knows what the examiners expect at each rung. At Frenchee, live lessons are taught by qualified native teachers, one to one or in a small group of three to five, with no subscription, and the session you are aiming for can be named in the first lesson so the calendar is worked backwards with you.
