Scottish Championship

The Scottish Championship is the second tier of the Scottish Professional Football League, the league competition for men's professional football clubs in Scotland. The Scottish Championship 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 Premiership, swapping places with the bottom-ranked club of the Premiership. The clubs finishing 2nd, 3rd and 4th then enter the two-legged Premiership play-off. The 3rd-placed club plays the 4th-placed club, with the winner then playing the 2nd-placed club. The winner of that game then plays against the 11th-placed Premiership club. If the Championship play-off winner prevails, the club is promoted and the Premiership club is relegated; otherwise, the Premiership club remains in its league while the Championship club is not promoted.
For promotion and relegation, the Championship play-off system closely mirrors its Premiership counterpart — the bottom-ranked club in the Championship is automatically relegated while the 9th-placed club undergoes a play-off with the 2nd, 3rd and 4th placed clubs from League One.
