Scotland Soccer League were composed by 10 teams, adopting four round-robin (each team according to subject and identity and battle other teams away from home four times). The points calculation method for a single game is that the winner gets 3 points, the loser gets 0 points, and the draw gets 1 point each. In the 21-22 season, the first place in the league will be directly promoted to the First Division, and the teams ranked second to fourth will have a play-off with the penultimate team in the First Division. The relegation play-offs will be played between the bottom team of the Soviet Union Second Division and the champion of the next level, competing for a place in the Soviet Second League next season.
