USA Field Hockey has a number of different memberships for athletes, coaches, umpires and parents. The athlete memberships range from $25-$50 a year and include a membership card, insurance coverage, and a subscription to Field Hockey Life magazine. The coaches memberships are $85 and include all of the above plus a yearly background check and a rule book. All of these benefits are nice but not required for all field hockey players.
While Koa does not require their field hockey players to have a USA Field Hockey Membership many club teams around the country do. I believe it is an athletes/parents personal preference whether they would like to purchase a yearly field hockey membership. Some parents like the fact that their daughter will have extra insurance through USA Field Hockey if something were to happen while playing. I personally do not think that the membership should be mandatory for athletes but it does have great extra benefits of discounts to the apparel store and the ability to attend USA Field Hockey clinics and camps.
