I'd expect reflectiveness and perfectionism to potentially impact the vocab portion of the VCI index if she just gave minimal answers and didn't expand and the PSI index b/c speed really helps there and slow reflection doesn't.
For comparison, how many 90th percentile type of kids do you know since that's about where Dottie puts the scores you have? Does she appear dramatically more able than these kids?
I, personally, don't give a lot of credence to personality measures of giftedness (i.e. exhibiting personality signs of giftedness) b/c I know a lot of kids who are sensitive, deep, etc. and who are not intellectually gifted. It's one of those, all squares are rectangles, but all rectangles are not squares things. OTOH, reading at 3.5 is something I'd put a lot of more weight on when assuming giftedness (again, depending on how you are defining reading). Most 3.5 y/os don't read at all, though.
The other thing to consider is what measures were used to identify you as gifted as a child. I, too, was labeled gifted as a child, but was never given an IQ test for that id. (I did take two IQ tests later, though, as a teen and adult.) I mention this to play devil's advocate b/c it is entirely possible for a child of a similar ability to your dd or even lower to be identified as gifted in a school system based on performance or the verbal ability alone or a number of other things.
Cricket2 - both my husband and I were tested gifted. My husband is HG. I don't know what I am - I was only ever told that I had a high IQ. I do know that my brother, who was tested later than I was, is HG. We both scored in top 1% of our respective States in our final high school exams. We also have another child who is clearly HG, although we have never had him tested. He also read at 3 and was solving multiplication problems at 4. He is working 2-4 grade levels above his age in everything except handwriting (which is atrocious)and writing (which he hates doing). He is more obviously "gifted" than my 12yo, but we do not see an enormous difference. Our third child (6yo) has shown very little evidence of being gifted.
We suspect our 12yo may have some language-related issues as she does have trouble getting her thoughts out verbally. This is what really perplexed us about the results, which showed her as being strongest in verbal ability - we expected this index to bring her overall IQ down. Also, she doesn't go to school, so hasn't been labelled "gifted" by a school on the basis of her verbal ability alone. It was purely our observation based on her precocious milestones, her intense curiosity and attention span.
For example, she knew all her numbers and letters by 18 months, started reading whole words when she was 2-3 - and learnt to start decoding words phonetically when she was 3 1/2. By 4 1/2 she was reading short chapter books and has continued in this vein. Math is not her strong point, but she is well above average. I say this just to show that we had never really questioned her giftedness -surely this is not what you would expect from a child with "high average" intelligence . If she had been tested as a very young child, she would probably have scored in the gifted range. I've read in so many places that IQ is not meant to change, so this is why we can't understand what happened.
I'm regretting our decision to go with the cheap option of testing now. I probably should have sought out a psych with a speciality in gifted children who could give us a full report. However, like I said, we didn't expect it to be an issue, and just needed a "rubber stamp" to access a program. The frustrating thing is that if she had been at school, she could have used standardised State testing results for the application. She would have been fine with these, but as we home-school, she didn't have these results.
The more I've thought about this since I posted, the more I'm convinced there is something going on - whether it be the psych or some underlying LDs. I'm disappointed that such expensive testing has left us with more questions than answers!
