In Luxembourg, a grade system from 01 to 60 is used in secondary schools. A grade of at least 30 is required to pass. An insufficient mark (01-29) is called a Datz in Luxembourgish. The grades are distributed in the following way:
| 50-60 | Very Good | |
| 40-49 | Good | |
| 30-39 | Satisfactory/Sufficient | |
| 20-29 | Insufficient | |
| 10-19 | Poor | |
| 01-09 | Very Poor |
But in the secondary schools who are technique otherwise called général is much more different. It introduces intermediate grades (26-29, 36-39 and 46-49) whether the teachers will decide if the student will pass to the level is the next one or the past one.[1] Unlike the normal grading system (shown above), the grading system of the secondary school général has 5 so-called levels. The notes are :
| 50-60 | Excellent | |
| 46-49 | Excellent or strong | |
| 40-45 | Strong | |
| 39-36 | Strong or sufficient | |
| 30-35 | Satisfactory/Sufficient | |
| 29-26 | Sufficient or insufficient | |
| 20-25 | Insufficient | |
| 01-19 | Very insufficient |
