Four U23 teams were added to the league as part of a two-season trial, expanding the league from 8 to 12 teams. These twelve teams will play each other twice in a regular competition, after which the league is split, with the top and bottom six teams playing separate competitions from that point, continuing with the points gained. At the top end, only the champion is promoted as three teams are relegated from the
2022–23 Belgian First Division A to reduce the size back from 18 to 16 teams. At the bottom end, the team finishing last will be relegated. U23 teams cannot be promoted to the Belgian First Division A, but can suffer relegation, furthermore they always have to play at least one level below their A team counterparts, hence could be relegated despite not finishing last. ==Team information==
