Promotion and relegation
If eligible, the top team in each group is promoted to Championnat National 2. If a team finishing top of the group is ineligible, or declines promotion, the next eligible team in that group is promoted.This season a total of 40 teams will be relegated to Régional 1, as a result of the restructuring of the French leagues. This will result in teams finishing in the bottom three places being relegated, along with the four worst eleventh-placed clubs, calculated from results against the teams placed 5th to 10th in their group. Initially, it was planned the worst tenth was to be relegated, but the administrative relegation of FC Girondins de Bordeaux changed that.
Reserve teams whose training centres are categorised as category 2B or lower cannot be promoted to Championnat National 2 by the rules of the competition.
