Thanks for your replies. The private testing we did was for sensory integration. We are going through our insurance for the medical diagnosis of ADHD (or to rule it out). The private testing would be for giftedness. DD may not test well, due to her sensory seeking behaviors... she may sit under the desk and hunt for wads of gum, for example.
An ADHD diagnosis would have to come from our MD, not the school. The giftedness has to be tested by the district - they don't accept outside testing. However, the district will read private testing results, and perhaps be influenced by them.
