We used Belle Chenault for DD's first IQ test, which we needed to apply to Open Window. She was fine for basic IQ testing - warm and friendly with DD, and I think she got DD to show her stuff adequately. (DD nevertheless did not get into Open Window, but that's separate from the IQ testing, and I don't think Belle's report had any bearing on that.) If you suspect a 2E issue or something, you'll probably want an accredited neuropsych.
