Gifted Issues Discussion homepage Forums Identification, Testing & Assessment WISC IV results with large discrepancy UPDATE

My 6.5 yr old DD completed the WISC with these results.

VCI 104
PRI 141
WMI 116
PSI. 131

Due to the 37 point difference her FSIQ 130, is apparently not valid. She has also taken the OLSAT with these results.
SAI 132
VERBAL 131
NONverbal. 123


Any insight to the large discrepancy between VCI and PRI? Her PRI score is 99.7 percentile. She also had two 18 scaled scores on the subtests within Perceptual Reasoning.


WISC subtest
SI 12
VC 11
CO 10
BD 14
PC 18
MR 18
DS 12
LN 14
CD 14
SS 17

She was not tested on the 5 optional subtests nor the WIAT. Although, with the large difference I would like additional testing. She has Spanish twice weekly as part of regular class, but is not fluent. The psychologist did not have an accent. I don't think my DD has ADD or ADHD - she has not had any previous issues concentrating or staying on task.
Is it possible to get incorrect scores for one section of the test? From her OLSAT results I was surprised to see such a differene in verbal test scores even though they are only slightly related.
