There are 12 teams in Korea League. The first stage is the regular season and each team needs to play 33 rounds. The second stage is divided into two groups. The top six in the league will directly enter the championship group, and the last six will enter the relegation group. On the premise of the original points in the first stage, another 5 rounds will be played, and the final ranking will be determined by the total points. For the same points, the goal difference will determine the ranking. The top 3 teams in the championship group directly participate in the AFC group stage, the second-to-last in the relegation group and the K League Challenge League play-off winner determine the league qualification for next season, and the last one will directly drop into the Korean National League.
