Age Group Break-outs at meets

[nettyinpa]

I'm posting this again in this forum.

I didn't know where to post this but I've been wondering....how do they determine the age group break outs at a meet? Do they go by the age the girls are at the time of the meet? I read somewhere that they determine the age group by the age they'll be at the time of states. Can someone clarify this for me? My dd is a Level 4 and she has girls on her team that range from 6 up to 9 years old. I think they typically group them 6-7 year olds, 8-9 year olds, right? There are a lot of girls on my dd team that are 7 and will be turning 8 before the state meet in March (I'm in PA).

TIA!
