I know mine and I know my son's. I was tested in the 80's with the WISC in order to qualify for gifted services. I scored in the moderately gifted range.

DS was tested with the RIAS at age 6 in order to qualify for gifted services. He scored in the 99.99th percentile at 155. I'm not sure how that translates to other tests, though. I say HG+, because given how he operates, he seems to be in the exceptionally gifted range but doesn't have the EG IQ score that I see listed in most places.

We were considering additional testing because we were having a challenge advocating for full-time gifted services. (I'm not kidding here - 99.99th percentile. Insert eye roll). We may still do that to see if he qualifies for DYS, but we have to give it some thought given that it would cost a lot.
