HowlerKarma,
Don't go to a psych who isn't experienced with gifted. Why bother? What would they know about frustration and acting up or needing to DO something because the pace of the learning material is so slow...

It is way better to spend the money at a minimum on someone who is experienced with gifted children and would be really really nice that they know gifted Girls! Because girls aren't boys. Heh.

I've heard good things about "The Gifted Development Center" http://www.gifteddevelopment.com in Colorado I think. But there has got to be other good psyc ed testers on the West Coast.

But yes, meet with psyc first and ask lots of questions.
Best wishes!
