The individual schools districts is not in fact so disconnected with others as you suppose. The days are long gone when the school board members actually set policy for the schools. Today we have a national public school establishment which which spend more than the US Military collectively, and whose values and ideas dominate the thinking of school board members, administrators and teachers ever bit as much as Catholic teachings dominate the Church. No Child Left Behind was an effort to standardize public education in the United States. Right now the Secretary of Education is working to create a uniform curriculum for the whole country. One reason why the school are irreformable is that no one wants to admit the insanity of expecting a child in Maine to obtain the very same education as a child in Southern California. The great goal of public education is conforming national thinking to ideals of that Establishment.
I’m well aware of that, but teachers and school districts are just regular folks with no commonality, or relationship other than being in education and unions, they vary widely and are not handpicked spiritual leaders of a single church, with a single belief, a single relationship with each other, a single religion, a Pope, etc.
