The ALTA Sunday Women's Doubles League is made up of women 18 years of age and older and plays during the Spring and Fall seasons. Each Women's season lasts seven weeks ending in a series of playoffs, which lead to the City Championship at each playing level.
Teams are formed through individual effort at public facilities, neighborhood courts, and private clubs. Playing levels include, from advanced to novice, AA, A, B, and C. Within each level, there are up to 9 flights.
Movement within the levels and flights is determined by the winning percentage of the team and previous levels of its players. With so many degrees of competition, players are assured of facing off against someone of comparable ability and allows for a highly competitive match and fun tennis environment.
Starting in the Fall 2010 season, women will be able to play in both the Sunday and Thursday leagues. When a Sunday player first joins the Thursday team, her Sunday level will be factored with the level of the Thursday team. She will then have a Sunday level and a Thursday level.
