Gifted Issues Discussion homepage Forums Identification, Testing & Assessment High PSI relatively lower VCI and WMI

I don't think it's unusual for VCI to be closer to average and VSI/FRI to be much higher, especially in a "mathy" kid (which seems to, in general, describe your son). Preumably his VSI and/or FRI are higher?

I don't know about the relatively low WMI, though. I know that can also be common in gifted kids (having either or both PSI and WMI closer to average).
