Registering for the Sproochentest
You register through the INL’s MyINL portal, and as of August 2026 it costs EUR 75. The fee is refundable: once you have submitted your nationality application at your commune, you can claim it back. The INL releases more than 800 places a month, and says they are booked very quickly.
Last verified against official sources on 18 August 2026. Exam fees, dates and regulations change — always confirm on inll.lu before you register.
How do you register for the Sproochentest?
Through MyINL, the INL’s own portal. Available sessions appear there and on the INL’s event calendar, and registration happens in the same place. There is no separate paper route published, and no third party can register you.
How hard is it to get a place?
The INL states that more than 800 places are made available every month, and that they are booked very quickly. It also says the dates for all sessions are not published at once — new sessions are added regularly through the year.
The practical consequence is the INL’s own advice: check the platform regularly rather than waiting for a single release. A month with no visible dates is not a month with no sessions coming.
How much does it cost?
The registration fee is set at EUR 75. That figure is current as of August 2026 and is published by both the INL and guichet.lu — confirm it on the INL site before you pay, because a fee is exactly the kind of thing that changes without any third-party page noticing.
Can you get the fee back?
Yes, in the ordinary case. guichet.lu states that you can claim reimbursement of the registration fee, and of approved Luxembourgish course fees, once you have submitted your application for Luxembourg nationality to the civil registrar at your commune.
The order matters: the claim comes after the nationality application, not after the exam. Passing the test alone does not trigger a refund.
When should you sit it, relative to your application?
Before the application, not alongside it. The language condition for naturalisation is evidenced by a pass certificate, so the certificate has to exist before the file that relies on it goes in. And the fee is claimed back after the nationality application is submitted — which only works if the test has already happened.
Working back from that: sit the test with enough margin that one unsuccessful attempt does not derail your timeline. You cannot re-register until your result arrives, and places are released on the INL’s schedule rather than yours.
What if there are no sessions available?
It is the normal state of the platform rather than a sign that registration has closed. The INL publishes that the dates for all sessions are not released at once, and that new sessions are added regularly through the year — so an empty calendar today is not an empty calendar this month.
- Check MyINL regularly rather than waiting for an announcement — that is the INL’s own advice.
- Treat a visible place as something to take now. The INL says places are booked very quickly.
- Do not pay a third party claiming to secure a place. Registration is through the INL, and nobody else is in a position to hold one for you.
What should you check before registering?
- That the personal details you enter are correct — they are what the INL holds for your session, so treat the form as final rather than a draft.
- What identification and materials the INL asks you to bring on the day. This page does not list them, because the INL publishes that itself and it is not worth getting from a third party.
- Which sessions are actually open, on MyINL, immediately before you plan to book.
