AACCA, NFHS, and individual states have a big problem when it comes to regulating HS cheer.
First of all, you are depending on other coaches to be whistle blowers on other schools. That puts some coaches in a position they just don't want to be in, even if it is anonymous.
Secondly, the only thing the AACCA can do is take away your certification (which no one can prove has ever been done). We all know there are a ton of coaches out there that don't have any type of certification. So really what is the risk if no one ever gets hurt?
Third, The standard of care is so different from different states, and the AACCA or NFHS. While AACCA and NFHS tend to be on the same page we know states differ widely. If all of West Virginia competitions are on hard floor and they have to do fulls to win in their state, there are very few coaches that are going to follow AACCA or NFHS rules. And is it really their fault that their state isn't as stringent as AACCA or NFHS?
Fourth, all of the AACCA and NFHS rules and guidelines are seen by many as just suggestions. No one can really make a coach stop doing anything unless someone gets hurt and they get sued. That's a risk some coaches are willing to take.
In every other sport if a team does something illegal it won't fly because refs and judges would penalize the coach or team and they risk loosing the game or match. What we need for the NFHS (Not AACCA because pretty much all HS follow NFHS rules for all of their sports) to do is to enforce the rules for cheer. If they aren't followed then the SCHOOL gets fined. They need to hire people to go to each school at least once in a year and do spot checks and make sure during games they are following the rules. NFHS could pass off the cost for these people to the schools. The schools pay for refs for games and now if they want to have cheerleaders they would have to pay a fee to NFHS. I guarantee that if schools were being fined they would get their coach certified, or at the very least get the rules in the coaches hand and expect them to be followed. If the school is fined I'm sure the coach will probably be fired. The possibility of being fired would make coaches follow the rules.
