In this case, applicants can still pass the exam if the arithmetic average, rounded up to the next whole number if applicable, of the scores received in the 2 tests is equal to or higher than 50 % of the full score.
The registration form should be sent to the INL, along with the supporting documents, before the registration deadline.
If the physical or psychological state of the person applying for Luxembourgish nationality prevents them from learning Luxembourgish, a request for exemption from taking the Luxembourgish language test may be sent to the Minister of Justice, accompanied by a medical certificate from a medical specialist.
The level required to pass the spoken test is A2 according to the Common European Framework of Reference for Languages:
- ability to introduce oneself and use simple language to talk about one's family and other people, one's living conditions and training or occupation;
