The twelve teams completed the
round-robin by playing each other twice (once home and once away) by 24 April. Then, the league divided into three. The top four teams were separated from the rest and formed the '' 'Title group'
. The bottom eight teams were then subdivided into two groups of four, titled 'Relegation group A'
and 'Relegation group B' ''. In the event, the top four were F91 Dudelange,
FC Etzella Ettelbruck,
Jeunesse Esch, and
FC Victoria Rosport. In each of the three mini-leagues, each team played each of the three other teams in the mini-league twice (once home and once away). To these results were added the 22 results of the first stage. The overall points totals (and goal difference, etc.) were used to determine each club's position in its respective mini-league. After calculating the final results after 28 games, F91 Dudelange, the top team in the title group, was declared the league champion. The fourth-placed team in each of the relegation groups (
Union Luxembourg and
CA Spora Luxembourg in groups A and B respectively) was relegated to the
Division of Honour. This format is no longer used; the current season,
2006–07 uses a straightforward round-robin. ==European qualification==
