That might be true in the cities where the dem/liberals have destroyed everything. In our town we sent our son, who will be six in Sept. to Kindergarten las year. By the time he got out in June he could read second grade level books, do some multiplication and can add and subtract. We have a pretty good elementary school here and the teachers are pretty adept at keeping us informed of his progress and any issues he might have.
Your are absolutely right, schools tend to reflect the community. The schools in my community were very conservative. The majority of the teachers lived in the community and sent their children to the same schools.
A teacher friend of mine just changed schools because hers was so bad she did not want her kids going there. She moved to a school in a more stable community and she said the difference was astounding.
Unfortunately, my community has seen a lot of change recently, we are moving.
