You sat the exam this morning, and now you want one number: how many days until the results. Here is the honest answer, which almost no other page will give you. The Institut national des langues Luxembourg (INLL), the institute that runs the Sproochentest, publishes no results timeline at all. Not on the exam page, not in its FAQ, not on the MyINL portal, and not on guichet.public.lu's nationality pages.
Last checked: 12 August 2026, against the INLL Sproochentest page, the INLL FAQ and guichet.public.lu. If an official timeline ever appears, this page will carry it.
Whatever confident day count you may have heard in a candidate group, it does not come from the institute, because the official pages publish none. So instead of adding another guess, this page sticks to what the INLL actually commits to, and three of those commitments are worth more than a rumoured date.
The INLL publishes no results timeline. What it does publish: retakes are unlimited, you re-register once your previous results are in, and the certificate never expires.
What the official pages actually say
Strip away the forum threads and the official record on results is three sentences long.
First, there is no limit to the number of times you can take the Sproochentest. The INLL's own FAQ states it plainly, with one condition attached: you can only register again once the results of the previous test have been obtained.
Second, that condition is the closest thing to timeline information the institute publishes. Your results are the gate to your next registration. Nothing in the official pages promises when that gate opens.
Third, once you pass, the certificate is valid for an unlimited period. There is no renewal, no expiry date, no need to ever sit the exam again.
The diploma check to do before you even sit
One official detail matters before results exist. The MyINL exam page states that the information you provide at registration is reproduced on the diploma, and that no changes can be made once the data have been submitted.
Read that as an instruction. The name you type into the registration form is the name that will sit on your certificate, and that certificate feeds your nationality file. Check the spelling against your ID before you submit, letter by letter, accents included. It is a thirty-second check that spares you a problem no amount of waiting will fix.
If you passed
The language requirement of your citizenship application is settled, permanently. Because the certificate has no expiry, a pass at 34 still counts at 54. What the rest of the nationality file involves is covered in the language requirement for Luxembourgish citizenship.
Nothing about the exam ever needs to happen again. That is the whole meaning of a pass.
If you did not pass
You get as many attempts as you need. The rule to plan around is the gate above: re-registration only opens once your previous results are in, and each sitting is a new registration with its own 75 euro fee.
A retake is also statistically ordinary. The INLL's own statistics report, published in December 2022, counts every sitting from 2008 to 2022, and 69 percent of those who sat passed. The full retake decision, including what to change before the second attempt, is in failed the Sproochentest, now what, and the fine print of the attempts rule is in how many times can you retake it.
While you wait
Waiting without a plan turns into refreshing your inbox. Two better uses of the gap.
Keep your mouth in the game. Ten minutes of spoken Luxembourgish a day preserves what you built during preparation, and how the exam is scored is a reminder of why speaking is the part worth maintaining. If the result goes your way, you lose nothing. If it does not, your next attempt starts warm instead of cold.
And if you are employed in Luxembourg, look at congé linguistique, the paid linguistic leave for learning Luxembourgish. A possible retake window is exactly the moment to know your rights to paid study hours.
If you have not sat the exam yet and landed here while planning, start with what exam day looks like, then measure yourself with a free mock exam rather than a guess.
