Hi, We recently had my daughter tested for possible admission to our local school for Talented and Gifted. The psychologist Administered the wisc-iv. She received the following scores:

VCI 134/ 99th
PRI 106/ 66th
WM 113/ 81st
PS 83/ 13th
FSIQ Not valid due to wide subtest variance
GAI 123

Subtests:
Similarities: 19/ 99.9
Vocabulary 19/99.9
Comprehension 9/37

Block Design 12/75
Picture Concepts 11/63
Matrix Reasoning 10/50

Digit Span 14/91
Letter Number Sequencing 11/63

Coding 4/ 2
Symbol Search 10/50

The evaluator indicated that the VCI would probably qualify her for the program we are considering but that she might struggle because of her slow processing speed. He recommended further testing. But she isn't having any problems in school so I'm having a hard time justifying the expense.

I'm wondering if anyone has any insights. I'm especially curious why the comprehension score would be so much lower that the other two components of the VCI?
