Registering for the Sproochentest

Registration goes through the INL alone, online. LetzTest registers nobody and has no access to sessions: this page explains the steps so you take them at the right time.

Where registration happens

The Institut national des langues Luxembourg (INL) runs the Sproochentest, handles registration and issues the certificate. Registration goes through the MyINL platform, online. No private platform, LetzTest included, can register a candidate.

The step is separate from your nationality file, which belongs to the Ministry of Justice. The certificate is a document you then attach to that file.

  • Online registration on the INL MyINL platform.
  • Two exam sites named by the INL: Luxembourg-Glacis and Belval.
  • The certificate is issued by the INL, not by the exam centre.
  • Always confirm the arrangements with the INL before registering.

Places go fast

The INL states that 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 practical consequence fits in one sentence: check the platform several times a week rather than once a month, and start preparing before you have a date. Candidates who wait for their convocation to begin rarely have the time they imagined.

Session alert

LetzTest publishes the list of dates released by the INL and offers an email alert when it changes. That is a monitoring service, not a registration: booking still happens on the INL platform.

Fee, absence and further attempts

The registration fee is 75 EUR, an amount set by grand-ducal regulation according to what the INL publishes.

  • Registration fee: 75 EUR according to what the INL publishes.
  • Absence or withdrawal without valid reason: the registration fee is lost, a new registration is needed.
  • Number of attempts: the INL states no limit.
  • You must wait for the result of the previous session before registering again.

What to bring on the day

A valid identity document is required. The INL accepts, among others, a foreign passport, an identity card, a travel document for refugees or stateless persons, a residence permit or an immigration certificate.

Bring the document you registered under: a photocopy is not enough. Arrive early, both sites need time for access and setup.

  • A valid identity document, the original.
  • Your convocation, with the time and site printed on it.
  • Patience: the order of the papers is not the candidate’s choice.
  • Adjustments for a certified disability: request them from the INL in advance.

A realistic timeline

Between deciding to sit the exam and the actual date, count several weeks, sometimes more depending on availability. That delay is not wasted: it is exactly the preparation window most candidates lack.

The sequence that works: start training, watch the dates in parallel, book as soon as a slot matches your state of preparation, then spend the final weeks on the full exam format.

  • Week 1: placement test and choice of two favourite topics.
  • Weeks 2 to 5: targeted work on your weak criteria.
  • Weeks 6 and 7: full simulations, at real speed.
  • Final week: revise your sentence blocks, no new vocabulary.

Key points

  • Only the INL registers candidates, through its online platform.
  • More than 800 places a month according to the INL, and they go fast.
  • A 75 EUR fee according to what the INL publishes, worth checking before you pay.
  • Prepare before you have a date: that is what separates calm candidates from the rest.
