The ALTA Women's Senior Doubles League is open to women 45 years of age and older and plays during the Summer season. Each Women's Senior season lasts seven weeks plus two rounds of playoffs that 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.
The prior year performance of the team and previous levels of its players determine placement within the levels and flights. Individual players' levels are determined by their prior Women's Senior level or their Thursday or Sunday Women's level if no Senior level exists. The many levels of competition help assure players are matched against pairs of comparable ability and allows for a highly competitive match and fun tennis environment.
