any testing experts out there?


Recommended Posts

can you tell me what this means? I know the large span can can cause some issues.. but what are they likely to be. He shows no signs of add or adhd.



I'm not an expert, but I do have two children with lower WMI/PSI than VCI/PRI scores.


I think that your son's spread is likely to be in the "normal" range for gifted kids, meaning that gifted kids without LDs or ADHD or other issues tend to have somewhat lower WMI and PSI scores than their other scores. Here's an article from the Gifted Development Center about this issue: http://www.gifteddevelopment.com/About_GDC/whoaregiftd.htm


In contrast, my older son is gifted and *does* have other issues, dyslexia and ADHD. His WMI and PSI scores have always been between 80 and 100 (9th-50th percentile) with the PSI consistently quite a bit lower than the WMI.

I do testing for a living (clinical psychologist) and while it's difficult to say much with so little info provided, I can say that the spread you reported is not that large. The WMI/PSI are certainly lower than the other two, but they are still above average (if they were in the 70-80 standard score range, it might be more of a concern). These tasks are more likely to be impacted by "outside" factors, such as fatigue, boredom, and so on. The VCI/PRI scales tend to be a bit more stable over time because they include more subtests and a broader range of skills. I would say you have a gifted child who is likely to show some scatter in test scores for a host of reasons... Good luck and hth...
