The Women's Western Amateur is open to amateur women who have an up-to-date 18-hole handicap index that does not exceed 5.4 under the World Handicap System. The WWGA Committee limits the field to a maximum of 120 contestants.
The championship begins with 36 holes of stroke-play qualifying, after which the field is cut to the low 32 players for match play. In the event of a tie for the 32nd position, a sudden-elimination playoff will determine the final match play qualifiers. Five rounds of 18-hole matches will decide the Women's Western Amateur champion.
