The Primera División of the (Professional Football League), more commonly known as La Liga Mayor or La Primera, is the top professional football league in El Salvador. It was established in 1969, and in 2011 had 10 clubs. Initially the league was run as a year-long tournament, but since 1998 there are two tournaments each year, much like in many other football leagues in the Americas. The Apertura season runs from August to December, while the Clausura season runs from February to July. Of the 56 teams to have competed in the league, FAS has won the title 19 times, followed by Alianza and Aguila (16), Firpo and Isidro Metapan (10) Competition format La Liga Mayor follows the usual double round-robin format. During the course of a given season (Apertura or Clausura), each club plays every other club twice, once at home and once away, for a total of 22 games. Teams receive three points for a win, one point for a draw, and no points for a loss. Teams are ranked by total points, with the top six clubs at the end of the season progressing through to the finals. If points are equal between two or more clubs, goal difference usually determines their placement. Although when it comes to qualifying for the finals, if the team in sixth and seventh spot are equal on points, then a Repechaje or Playoff is needed to determine which team gains entry into finals. A system of promotion and relegation exists between the Primera División and the Segunda División. In May each year, at the conclusion of both the apertura and clausura seasons, the team with the fewest points on aggregate over both seasons, is automatically relegated to the Segunda División, while the team with the second fewest points must participate in a Repechaje or Playoff with the runner-up of the Segunda División. The winner of this home and away playoff will be guaranteed a spot in the Primera División for the following season. This means that every year, a maximum of two teams could be relegated from the Primera División depending on the results of the Repechaje between the second last placed team in the Primera División and the runner-up of the Segunda División.
