It is the Luxembourgish language exam required of applicants for naturalisation, run by the Institut national des langues Luxembourg (INL). It does not measure general Luxembourgish: it measures two skills, speaking at A2 level and listening at B1 level.
No. No reading, no writing, no grammar on paper. Both tests are oral: spoken production first, then listening comprehension.
The speaking test runs about ten minutes in front of two examiners, in two parts of roughly five minutes each. For listening, the INL states 35 minutes; other public sources mention around 25. Check the exact duration on your invitation.
One examiner runs an interview on a topic you choose from two offered, drawn from an everyday repertoire: work, training, family, friends, hobbies, food and drink, media, travel, languages, housing. It is not a monologue — the examiner follows up and asks you to be more precise.
You are shown three pictures, you choose one and describe it. What is expected is a simple but structured description: who, where, what, and what the scene suggests to you.
Three audio documents on a tablet — a radio news bulletin, a conversation between two people, then a longer, more structured exchange or talk — each followed by multiple-choice questions. The documents are spoken at natural speed.
On eight criteria, marked on the spot by the two examiners: range, basic grammatical structures, fluency, clarity, task completion, coherence, making yourself understood, and interaction.
You pass by scoring at least half the marks on the speaking test. If speaking falls below that, it can be compensated: the exam counts as passed when the average of the two tests reaches at least 50%.
Registration is only with the INL, online, through the MyINL platform (myinl.inll.lu). LetzTest registers nobody for the exam and has no access to sessions.
From what the INL publishes, the registration fee is €75, set by grand-ducal regulation. Check the amount in force when you register.
The INL lists two exam sites: Luxembourg-Glacis and Belval.
The INL says it makes more than 800 places available each month and that they go very quickly. Sessions are not all published at once: new dates are added regularly.
The INL states there is no limit on the number of applications, but that you must wait for the outcome of the previous session before registering again.
From what the INL publishes, the certificate has no limited period of validity: once you have passed, you do not sit it again.
A valid identity document — the one you registered with; a photocopy is not enough. The INL accepts, among others, a foreign passport, an identity card, a refugee or stateless travel document, a residence permit or an immigration attestation.
No. LetzTest is a private preparation platform, independent of the INL. Registration, the exam itself and the certificate are handled exclusively by the INL.
No. They are estimates produced by our tool for practice, on the same eight-criteria grid. Only the INL examiners mark the exam.
Yes. A real speaking question is marked straight away on the home page, with no account and no card. The demo adds a listening task and a picture description.
€130 for six months of access, paid once. When the six months are up the access simply ends: nothing renews, nothing is charged later, and there is no subscription to cancel.
No. The speaking exercises record in the browser on a phone or a computer; headphones make the feedback cleaner. The recording is transcribed, then marked on the eight criteria.
The programme is written over eight weeks at twenty minutes a day: a starting point, targeted work on your weak criteria, then full mock exams. It adapts if your exam date is closer or further away.
