Everything about your local public school is signed off on by your elected school board.
The one most consistent thing that I have watched over the years as a teacher is how school district administrations will do almost ANYTHING to avoid conflict with the school board.
If you don't like what's happening in your schools, elect a school board that shares your, or the community's standards/values.
That's about the only thing that I saw throughout my career in education that will actually make a difference in what the school district does.
It often gets ugly, but I've noticed that educational administrators tend to be more sympathetic to community wishes when they realize that their ridiculous compensation package is on the line.
Our local board is controlled by teachers from outside the district who reside in the district.
