I agree with keet. I know it's a little more out of pocket expense to go with a private psychologist, but I'm a firm believer that you are likely to get a more unbiased result. This comes from years of working in public schools (in an exceptional student education department) and from our experience with our son's school. Make sure you find someone who is experienced in testing gifted children.
I've never heard of "attentiveness" referred to in a percentage. Interesting. If the school hasn't done its testng yet, I'd get an opinion elsewhere first. Often, a school wants to diagnose ADHD, but what's really happening is they're not challenging your gifted child. The symptoms of a bored gifted child and a child with ADHD are much the same.
