Doc both those sites you posted have skin in the game, we wont get a fair assessment from them.
Where you can get a fair assessment is from teachers and supvs. I have one of each one daughter is a vice principal now and the other a teacher.
One has 24yrs ther other 20, both are totally disgusted with the rules they are forced to follow and the curriculum. It used to be they made their own lesson plans and just taught them and periodically an assessor would sit in their classroom for a couple of days and assess their demeanor and the content.
Today lesson plans are handed to them pre written and they are told how much time to take out for non subject related class room instruction which you can guess is a Liberal cluster of PC and other crap.
They both strongly disagree with what they are forced to do and teach. Both were always very liberal and voted strictly democrat.
