The Championship had 16 teams, of which three were U-21 teams, the eldest youth teams of the Super or Challenge League clubs. The number of U-21 teams permitted in this division was limited to four (until 2022) and they were not eligible to promotion. The top placed team, of those eligible, would be promoted and the two teams lowest in the table would be relegated. However, the start of the season was delayed and the format of the league was modified due to the
COVID-19 pandemic situation. In the first stage each team played once against each of the other 15 teams in a round robin format. The table was then divided into two equal groups. The top eight teams again played once against the other seven for the promotion slot and the bottom eight played once against the others to decide relegation. ==Teams==
