The link you sent is very informative. Dear Penny, I have to resist the urge to tell you what to do. In the end, you are going to make your own decisions. Good ones, I trust. The best I can do now is tell you how your situation looks from my perspective.
Control is what they do.
It's all they do. I doubt if they know much about education, but they clearly know a lot about control. They control your child as surely as if she were a convicted felon serving a prison sentence in a maximum security institution. Furthermore, they seem to be controlling you. That isn't education.
