Geez, good luck, Pemberley, with what has turned into a true marathon.
One wonderful thing you've done is that your daughter sees that YOU care. She can see that you trust and respect her. Good luck finding a place she deserves.
BTW, what is an "OOD placement"? I googled OOD and the first result was: "The Ood are a fictional alien species with telepathic abilities from the long-running science fiction series Doctor Who...." Which may seem to fit with some of your strange experiences, and it would be pretty cool if your daughter was in a situation with teachers who were telepathic, but I am guessing that's not what you meant!
