"If subtest scaled scores differ by 5 or more points, then that composite index is not interpretable, and should not be used. So, your dd's perceptual reasoning index is not interpretable, and the individual subscores should be considered instead. This information is from:
Essentials of WISC-IV Assessment
By Dawn P. Flanagan, Alan S. Kaufman
I think this means that the GAI isn't even considered a good measure for your dd."
So if Pud had in Verbal Comprehension:
Vocabulary: 16
Similarities: 19
Comprehension: 9
Does that mean the VCI is not interpretable? What if no substitute tests were given? Hmmm. Makes me wonder.
ETA: And, yes, that stupid 9 still bothers me!
