Scottish League One
The Scottish League One is the third tier of the Scottish Professional Football League, the league competition for men's professional football clubs in Scotland. The Scottish League One was established in July 2013, after the Scottish Professional Football League was formed by a merger of the Scottish Premier League and Scottish Football League.
Format
Teams receive three points for a win and one point for a draw. No points are awarded for a loss. Teams are ranked by total points, then goal difference, and then goals scored. At the end of each season, the club with the most points is crowned league champion. If points are equal, the goal difference determines the winner. If this still does not result in a winner, the tied teams must take part in a playoff game at a neutral venue to determine the final placings.Promotion and relegation
The champions are directly promoted to the Scottish Championship, swapping places with the bottom club of the Championship. The clubs finishing 2nd, 3rd, 4th, and 9th in the Championship then enter the two-legged Championship play-off. The 2nd-placed League One club plays the 3rd-placed League One club, whilst the team who finished 4th in League One will play the 9th-placed Championship side. The winners of these ties will then play each other. If a League One play-off winner prevails, that club is promoted, with the Championship club being relegated. If the Championship side is victorious, they then retain their place in the Championship.The League One play-off system is consistent to its Championship counterpart, in which the bottom club of League One is automatically relegated and the 9th-placed club undergoes a play-off with the 2nd, 3rd and 4th placed clubs from League Two.
