Twenty years of residence in Luxembourg replace the exam with a course. If you are an adult and have been resident in Luxembourg for at least 20 years, guichet.public.lu says you can take a 24-hour introductory Luxembourgish course instead of the full Sproochentest.
No exam room. No examiner. A course you attend, and the language requirement is met. If you have spent two decades assuming the Sproochentest stands between you and a Luxembourgish passport, this page is the correction.

What the rule actually says
The state's portal states the exemption in one sentence: an adult who has resided in Luxembourg for at least 20 years can take a 24-hour introductory Luxembourgish course in place of the exam. Guichet files this route under acquiring nationality by option, and it adds one precision worth knowing: the residence must have been uninterrupted over the last 12 months.
The rest of the option file has its own conditions, and guichet's conditions page owns those details. What this page owns is the language piece, because that is the part people wrongly assume means an exam.
Two different 24-hour courses. Do not mix them up
Here is a mix-up to avoid: Luxembourg's nationality rules involve two separate courses that both happen to last 24 hours.
| Course | What it is | Who it concerns |
|---|---|---|
| Introductory Luxembourgish course, 24 hours | A language course that replaces the Sproochentest | Adults with at least 20 years of residence, on the option route |
| "Vivre ensemble au Grand-Duché de Luxembourg", 24 hours | A civics course: fundamental rights (6h), state and communal institutions (12h), history and European integration (6h), or a test on those topics instead | Required for naturalisation alongside the language requirement |

The civics course also has an exam alternative: per the Ministry of Education's course and exam page, a computer-based multiple-choice test organised at Esch-Belval, with the certificate issued by the Service de la formation des adultes. So when someone tells you "after 20 years you just do a 24-hour course", ask which course they mean. The answer decides what you will spend those 24 hours learning: Luxembourgish, or civics.
How the course route works in practice
Guichet names the organisers of the 24-hour Luxembourgish course: the Department of Adult Education (Service de la formation des adultes, SFA), its organising institutions in the approved sector, which are communes and non-profit organisations, and training organisations with approved course programmes. In short, you enrol through an approved provider, not through the INLL's exam portal.
Then comes the step nobody warns you about because it is so ordinary: paperwork by post. Once you have completed the course, guichet instructs you to send the course attendance certificate, together with a stamped, self-addressed envelope, to the Department of Adult Education. Buy the stamp the day you enrol and the finish line will not be delayed by an empty envelope drawer.
Under 20 years? Here is your honest picture
If your residence clock stands at 8 or 15 years, the exemption is not yours yet, and waiting years just to dodge an A2 oral exam is a poor trade. The standard path is naturalisation: at least 5 years of legal residence with the final year uninterrupted, per guichet.public.lu, plus the language requirement and the civics course or test above. The full language rule is broken down in the citizenship language requirement.
The exam itself is smaller than its reputation. Is the Sproochentest hard gives the honest difficulty picture, and the institute's own numbers back it up: per the statistics report the INLL published in December 2022, 69 percent of those who sat the exam between 2008 and 2022 passed. Attempts are not rationed either; you re-register once your results arrive, and the retake path is simple and unlimited.
So the real decision is not exam versus no exam someday. It is whether your 20 years are already behind you.
Which route is yours
Count honestly. Twenty years or more of residence, and thinking of the option route: confirm your full conditions on guichet, then find an approved provider for the 24-hour introductory course, attend it, and post the attendance certificate with your stamped envelope to the SFA.
Short of 20 years: stop waiting and start talking. The speaking test rewards a few months of steady out-loud practice, and why become Luxembourgish is the reminder of what the passport is worth. A free mock exam will tell you today how far from A2 you actually are.
