I've actually never heard of school teams in reference to levels, aside from certification levels for coaches (unless they are competing in allstar competitions such as Jamfest, which uses allstar leveling). Typically school divisions are divided by school size/squad size and possibly into novice/intermediate/advanced for competition for some companies, and then sideline just follows NHSF/AACCA rules (i.e. no baskets for middle schools, no double twisting dismounts, etc.). I would inquire about it with the coach when possible, as the VHSA website had nothing about levels/stunting restrictions on there.
If your daughter's team is like most MS teams (lots of first time stunters), I wouldn't encourage them to do anything above halfs really. Anything more than that typically gets janky real fast at that age in school cheer overall, because the first year girls don't understand technique and start to use back/arms/etc. instead of legs to lift for more difficult stunts. Out of all the camps I've staffed, most MS teams have maybe one strong group (of all star kids lv 1-5) that can do extensions, and the rest I'd have to reiterate technique for preps over and over and over.:confused:
