Competition format
The top six teams at the end of the regular season enter a knockout stage to decide the Champions of France. This consists of three rounds: the teams finishing third to sixth in the table play quarter-finals. The winners then face the top two teams in the semi-finals, with the winners meeting in the final at the Stade de France in Saint-Denis.The LNR uses a slightly different bonus points system from that used in most other rugby competitions. It trialled a new system in 2007–08 explicitly designed to prevent a losing team from earning more than one bonus point in a match, a system that also made it impossible for either team to earn a bonus point in a drawn match. LNR chose to continue with this system for subsequent seasons.
France's bonus point system operates as follows:4 points for a win.2 points for a draw.1 bonus point for winning while scoring at least 3 more tries than the opponent. This replaces the standard bonus point for scoring 4 tries regardless of the match result.1 bonus point for losing by 5 points. The margin had been 7 points until being changed prior to the 2014–15 season.
Relegation
Starting from the 2017–18 season forward, only the 14th placed team will be automatically relegated to Pro D2. The 13th placed team will face the runner-up of the Pro D2 play-off, with the winner of that play-off taking up the final place in Top 14 for the following season.Fixtures and results
