The test was the WISC-IV and I'm not completely sure what the VCI, etc. you asked about are but I'm assuming this is verbal comprehension, perceptual reasoning, etc. Going on that assumption, the VCI was 138, the PRI was 119, the WMI was 107 and the PSI 85 and the full scale was 120. The very low PSI was the killer. We have since found out he has a visual perception/tracking problem which causes problems with the way he perceives things. This causes problems with lining numbers up, patterns, etc. This is what I believe caused the skew in the scores but of course I have no proof of that.
Any opinion or advice would be most welcome!!! :-)
