The psych did say that we will receive in the mail copies of all of the scores/information on the academic and IQ tests that they can legally give us.

I'd hang back a little and see what information they do give you, before you start launching your legal campaign.
Do you know what IQ test she was given?
I am quite confused as to why they can't give you the full info you are requesting? What logic was that law based on?
