 Between 2007–08 and 2010–11 the league was made of one division of 12 teams in a round-robin tournament with the top club winning the championship, with a deciding play-off match to decide the winner if the two teams were tied, as was the case in 2009–10.In 2010–11 the IFA re-introduced a second division that previously existed in 2006–07.Since 2011, the participating clubs first play a conventional round-robin schedule, followed by a championship playoff contested by the four top teams, where they meet each other twice.
