"Should state schooling be the default position against which others are judged?"
Philosophy professor Christopher O. Tollefsen doesn't think so. He says it's a faulty assumption, "widely shared amongst liberal theorists of education" (and, I would add, amongst nearly everyone under the dome at NE 23rd & Lincoln), "that the state is in some way a privileged player in the question of children’s education. According to this view, the state should educate children, and others who claim a right to do so should be subject to special scrutiny or meet a special burden of proof."
There are signs that that attitude is beginning to change in Oklahoma, that private and home schools are starting to get their due. Stay tuned.
