Hello, This is my first post here. I'm usually a lurker, but I thought I have some data to share.

My DS8 was tested on the SB5 and the WISC IV (VCI only as supplemental) on the same day, by the same tester last June.
Here are the results...

SB5

FSIQ 139
Nonverval IQ 131
Verbal IQ 144
Abbreviated IQ 142

WISC IV
VCI 148

It is interesting to note that WISC IV VCI score (148) is higher than SB5 Verbal IQ(144) by 4 points!

Also, his highest index score on the SB5 is Fluid Reasoning.(141)
He is a mathy kid, so I thought he would score highest on Quantitative Reasoning Index.......

He was also tested on the WJ III on the same day.

WJ III Achievement

Total achievement 162
Broad Reading 143
Broad Math 173
Broad Written Lang 146

Since his Verbal scales (both on SB5 and WISC IV) are the highest, I thought Broad Reading score was higher...
I thought it is interesting...
