I just PM'd you ELH, but since I found the relevant data outside of a PM, I'll say that I think your son's GAI is actually 139, which of course helps close the gap some...

ELH:

Your DS sounds rather similar to mine. The WISC GAI and FSIQ are similar, and it sounds like the reasons are similar. Also, DS's memory and speed scores were quite low. I suspect a poor rapport with the tester, but also suspect, like you, some hidden 2E issue, which no one to date has been able to put a finger on. The uncertainty is a big part of what's driving us to the JHU extreme (in terms of $).

I'll just throw this out there for informational purposes. My DS has a visual processing/tracking issue that he is received therapy for. I have a friend who's daughter is GT but struggling in some areas and it was recommended that they take her for testing that could cost in the thousands. I mentioned the visual issues to them and they researched it and it turns out that IS what is wrong with their DD. It saved them lots of money and she is getting the help she needs. Check out www.covd.org to see if this sounds like something that might help.

I have a question about this, E&CMom, but I'll start a new thread so I don't hijack this one. Would you follow me over, please? As well as anyone else who knows about vision issues.

Thanks muchly!
