No one is exactly sure yet as Aspire has not come out with the regulation governing the league. Teams and/ or clubs may be able to get promoted from Aspire to GA. Aspire has a national championship and regional ID events. But I think so does NAL.

Players in Aspire should be able to play in GA is needed as a guest player.

What’s the difference between GA Aspire and NAL for girls? Sounds like both are 2nd tier leagues for clubs with GA. In MD:

GAA: Baltimore Armour/SAC
NAL: Baltimore Celtic, Liverpool(?)
