It is actually a very smooth process--the form consents to testing and then they use the IAS. Yes, you can turn down a change in placement. I just wanted to have control over the info., kwim? And my older dd was MG on her testing at 6 (I think due to perfectionism)--I would just hate for it to be an underestimate of her abilities and then limit future options. I guess it is pretty simple--we either need to pay for private testing or request the school do it. I still don't know what the right thing is. She is not miserable or anything.
