I think that getting a private Psychologist who is willing to do a 'chart review' might be a worthwhile investment, if that's possible for your family. The Psychologist can then give you the information you need. If your child is 2E, perhaps you already have a trusted resource that can advise you. Perhaps a willing Pediatrician might be willing to send such a letter on your behalf.
