Let me first say that those scores ARE impressive and you will for sure need to look for accommodations for you DD. She is without any doubt gifted.
Hmm... Those scores seem to "fit" the index scores. It's really only the FSIQ that seems off to me. And to be honest, I'd never even heard of the general language index, and wonder how that factors in (I checked, that falls under optional testing and does not feed into the FSIQ). Hopefully others with similar WPPSI data will chime in.
I agree with Dottie. I think the tester made a mistake when calculating the FSIQ. It's quite possible that she/he did indeed added another subtest score to the test.
I am not an expert when it comes to scores but I do have my son's results in front of me. His subtest scores are higher by quite a few points than your DD's results but his FSIQ is noticeably lower.
Dottie, my son's report includes General Language score.
