Your question was bit of a stumper with the high number of uninterpretable scores.
Yes, I cannot believe how many not interpretable scores we had. The report says "Behavioral observations indicate a strong need for feedback and some perfectionistic tendencies." and goes on to talk about how her perfectionism may have actually lowered her score in the timed tests.
The other thing that seems odd to me is that the tester said that "Her home school experiences appear to have been notably enriching for her, given her high achievement score that exceeds her cognitive score." Well -- I'm not that good a home schooler. I see my friends who do all kinds of enriching things, and compare them to me, and I'm really not in their league as a homeschool teacher. My ego would like to believe that I am doing a fabulous job of homeschooling, but I don't think so. That one sentence, more than any other, makes me question the cognitive results and makes me think that the IQ score is not accurate.
