Schools in America report to superintendents who report to elected school boards. School boards usually have frequent school board meetings where citizens can bring their concerns. If you don't like a policy you can bring it to their attention. If you get nowhere with that you can petition for a referendum on a ballot. Or you can campaign to unseat school board members who don't see things your way.

If the democracy of the process bothers you, would you be any better off with anarchy?
