all star cheer is only recently established where i live, but it is growing quickly. last year we had 3 girls on an all star team for the second half of our school year. this year we have a half dozen on all star. they are all at the one gym, and we knew before our try outs what teams they were on so we wrote out their schedules and made sure none of our practices conflict (we do this with dance classes, soccer teams, hockey teams, rugby teams, and the glee/ cabaret club too). it means long days for a couple of the kids who multiple practices in the same day- but they (and their parents) knew in advance what they were signing up for. if any of the kids have to miss our practices for another activity we evaluate whether its weekly or sporadically, and for what length of time they miss, and determine whether we can take them as a full member or an alternate. we had 5 kids choose our program over another activity this year.
our competitions don't overlap because the all star teams travel out of province, and we stay in.
the only issue i have had is attitude. some of them are on teams that are a higher level than their high school and have a habit of saying how hard it is to do things at prep level since they are sooooo used to extended and how these skills are sooooo easy etc. we have had other team members say how they make them feel bad when they say that stuff as if they are better than them. you also end up with the conflict of their all star coach having them do something one way, and their high school coach another way.
we take our all stars aside at the beginning of the year and have a group chat about these issues so they know ahead of time how it makes people feel and that its not tolerated. we never want them to feel bad about being on all star, or not be able to talk about it but we do let them know there is a time and a place. they know they aren't to boast in practice, but we are always happy to hear about their all star cheer before or after practice times and we frequently get texts/ emails/ messages from our all star kids asking us for tips on skills they are working on, and right after their practices telling us about the new skills they did that day and how excited they are.
