Who cares what system is in place to advance a band to state.
Your job as a teacher is to figure out how to navigate it and try to be successful using it.
There is nothing stopping you from putting on a fantastic top-notch performance no mater which system is in place.
It is not the system trying to keep you down but your own thoughts about how this system seems unjust because it will not allow every 1A band to get to state and some bands who make a 1 will have to stay at home.
If you want to go to state, step up and present a state worthy show.
