I wanted to reply to this thread even though it's an older one.

We live in the Philadelphia metro region and used a private provider for IQ and achievement testing. It was a psychologist with 20+ years of experience, both in private practice and in one of the top Philly-suburb school districts. Our experience with her was very good. If you want more information about her, you can send me a message and I'll fwd her information to you.

Best,
Tara
