OK, I am completely confused. MY dd 10, recently took the WISC iv. There are severe discrepencies between the subtests which I have read if there are discrepencies over 15 points then a learning disability is likely. However, I also read to be diagnosed with a learning disability, there has to be discrepancies between IQ and achievement, which there is not. She has a very low processing speed. Has a hard time with math and despises writing.
Here are her scores
VCI 146 (99.9%)
similarites 18
vocabulary 18
comprehension 17

PRI 121 (92%)
block 11
picture concepts 15
matrix reasoning 14

WMI 107(68%)
digit apan 10
letter number sequencing 13

PSI 85(16%)
coding 6
symbol search 9

FSIQ 123
GAI 140

She is very much an Introvert and a perfectionist. Everything she scored low in has to do with visual motor processing. However, it is noted by the tester that she completed the harder designs but not the easier ones. She is an avid reader and started reading at 2.
How do I know if the processing issue is a disability or just her personality? Most likely a Visual Spatial learner.
Also, knowing that she has a slow processing problem I don't think that the WISC iv was the best test to determine IQ. She always freaks on timed test. I also read that:
Quote
If a child "hits the ceiling" on several subtests, his overall score may be lowered by his lower subtest scores resulting in an artifically depressed overall score. This is particulary true of 2E.
The most comon wisdom is on the WISC, a ceiling is a score of 17-19 on a subtest and the whole test may be an underestimate if 2 or more subtest ceiling are reached. Supplemental testing should be performed with the Stanforn Binet LM

Should I pursue additional testing? How would I find a tester that still uses the SB L/M? The extended scoring on the wisc did not raise her score at all.
What tests should be done to see if there is an LD? Thanks for your responses. I have been completely stressed about this because obviously I want to help her if there is a problem and I have been trying to advocate for a grade skip and worried that these test scores will not help my cause.
