Format
Due to COVID-19 pandemic in Iran the format of the league changed from normal round-robin in previous seasons to new format: 11 teams divided into two groups of 5 and 6 teams. In each group, teams played against each other in two home and away matches. After the end of these matches in both groups, winners and runners-up of each group (total 4 teams) qualified to final stage and the lowest ranked team in each group (total 2 teams) relegated to Women 1st Division. In final stage, four teams played against each other in a round-robin home-and-away format in 6 weeks.
