At every meet we've ever been to, they place the girls individually and in age brackets (7 & under, 8 yr. 9yr, sometimes even 8a/8b etc. if the groups are large). The smaller meets may choose to place everyone out, the larger ones usually do either 1/3 or 1/2 out in the age brackets. So, if there is- 20- 9yr olds, and they're placing 1/3 out in events, then 7 girls will get placement medals. Almost all meets place at least 1/2 out on AA. So at the example meet, 10 would get medals or trophys for AA.
The large meets will usually have a website that will also list results. Then,even if your dd didn't place in the top 1/2 at the meet, you can still go online later and look up how she placed in her session. I really like when they put it on the website.
I've never heard of a meet, unless it's a practice meet or a learning meet or maybe level 3 & under, that doesn't place kids as individuals. Granted I've never watched level 3 & under meets, as we don't compete those levels at our gym, but maybe they don't do placements, idk.
We're from OH, but compete in OH, IN, and one meet in FLA. Hope that helps out.
