Parental complaint is useless so long as the schools have any connection with the Federal Government at all. Get your kids the hell out. There is no history in public school, no teaching of calculation, little teaching of reading and none of grammar. There is lots of social programming by a system that is reducing all individuals to interchangeable units of labor with zero reasoning ability and zero loyalty or even awareness of anything greater than themselves other than the All Wise Government.
