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 (US Rumelange and FC Avenir Beggen in groups A and B respectively) played off against the third- and fourth-placed teams in Luxembourg's second division (FC Mondercange and FC Mamer 32), the Division of Honour. The winning team in each tie was awarded a place in the National Division in the 2006-07 season, whilst the losing team was confined to the second division. The matches were played on 28 May on neutral ground. Both National Division teams lost, thus were relegated.
