I finally resorted to allowing him to type his assignments so the dysgraphia wouldn't hold him back.
That is a totally reasonable accommodation and one that I'd seek in a 504 if he starts attending school.
...dug up his other test scores to see how far off he was on the Verbal score for Davidson. We have several 99% from WJIII tests (we do it yearly for our state requirements) but I'm seeing there is a long way between 99% and 99.9%...
I've noticed much discussion of VCI, PRI, and GAI scores here, though those exact terms were nowhere on the test report. When you say VCI, is that just the Verbal score alone? Is there a way for me to determine those? That would really help me in applying what I'm learning from old posts.
VCI is verbal comprehension index and is made up of the scores from the similarities, vocabulary, and comprehension tests. Information and Word reasoning are optional tests that can substitute for others in the VCI. I'm not sure which ones they can fill in for, though. Dottie would know if she pops in here.
PRI is perceptual reasoning index and is made up of scores from block design, matrix reasoning, and picture concepts. Picture completion is, again, an optional subtest that can substitute somewhere in here.
WMI (working memory) and PSI (processing speed) are essentially supporting skills that enable the child to utilize his cognitive skills (VCI and PRI). A child with much lower supporting skills may have a harder time implementing his ability and a GAI can be used to estimate his cognitive ability when WMI and/or PSI are pulling down the full scale IQ. You can calculate the GAI yourself utilizing the WISC
technical report #4. Let me go back and look at your original post and I'll be right back to let you know what # I am coming up with for a GAI. I suspect that his lower PRI might also make that number a less than ideal estimation of his ability, though.
eta: I'm coming up with a GAI of 128 (97th percentile) with those scores.
Also, how rare is such a large gap--the 85 processing speed vs the 136 verbal were quite shocking to me, as well as the 70 on writing fluency.
Big gaps btwn speed and VCI/PRI are not hugely uncommon in the gifted population but your son's seems a bit larger than most I've heard people mention. My two girls have VCI scores in the 98th-99.7th range and PSIs at around average. One of my dds also has an average WMI score and the other has a WMI score on par with her PRI/VCI.
