The other problem with private schools, Christian included, and maybe more so for Christian, is that they often get the kids who get kicked out of public schools for being too unruly, or the parents figure that the Christian school will straighten out the mess of a kid they raised.
My kids know lots of kids who go to the local Christian school and it does have it’s share of problems, not the least of which is the teachers. One girl was warned of facing a brief suspension for cheating on her homework. ??????
