I got my 2e/eg/pg son tested last summer with the WPPSI when he was 5.5 yrs old. The tests came back scattered and inconsistent. The neuropsychologist gave us a diagnosis of ADHD, Asperger's, and anxiety disorder - which I have since learned from neurofeedback, which started in Aug, are invalid and misdiagnoses. Insurance paid for the WPPSI though.
In Feb, my son did the WJ-III achievement tests through public schools - so we didn't pay. He scored better on these tests but didn't perform completely to his ability and underperformed, particularly in math.
In June, I took my son to a 2e specialist. She looked at the WPPSI and WJ-III scores and said he was ADHD - but like I said, I have since learned from neurofeedback in Aug that this was a misdiagnosis. 2e specialist said if we did neurofeedback that it would likely take care of our '2e' issues and that if we had him re-tested in a couple of years we would probably get the test scores we expected.
Well, if we didn't start neurofeedback, then we would have NEVER known that our 2e DS didn't have ADHD. So I don't have a lot of faith now in these tests or 'experts' to be honest, even if our DS's situation is unusual.
2e specialist confirmed he was gifted - but we already knew that because he had been at two private gifted schools and I was told that he might be eg/pg from one them. So she didn't really tell us a whole heap that we didn't already know.
In hindsight, I'd say that there could be a number of reasons why a child has performance anxiety. Probably some due to self-esteem; some due to the type of learner; some due to the type of thinker; some due to attentional deficits; and on and on.
The issue is the attentional deficits and how they can affect test scores regardless of a child has ADHD or not. My two cents is that you might be better off devoting your energies to finding out whether your child has ADHD or not yourself and seeing if medication or alternative treatments, such as neurofeedback, might help.
Neurofeedback is eliminating or greatly reducing the need for medication; your insurance may even cover it. It might be worth investigating. It's more objective and based on actual brain-based activity rather than a paper-pen test or clinical observation. Brain wave activity can show whether the theta waves are too high to show if ADHD is present.
There are various books and checklists online to confirm that your child may be gifted. Like Polarbear said, the test results are not always reliable at this age or point. It's only a snapshot of child. It can provide you with a paper trail though. If the insurance pays, then I might be tempted to create some documentation. But be wary and skeptical.
