marytheres, I don't know much of anything about the SB, but fwiw, when our ds was tested by the school he was given the WJ-III Test of Cognitive Abilities, which I also knew nothing about at the time... so what I did was google "(test name) + description of subtests" and I was able to find detailed info about each subtest, what it tested plus how it was administered (prompt+response+timed/untimed). That was enough info for me to figure out how to compare subtests between the WISC and the WJ-III. I'm guessing you're interested in seeing if the scores dependent on vision have improved since he's been through VT? My ds had a low coding speed on the WISC - the corresponding WJ-III test that relies on fine motor (my ds' challenge) wasn't named "coding" but it was easy to see in his scores - there was that same huge dip (BUT.... there was no reason to anticipate that my ds' score might have gone up so I was expecting to see the dip). In some ways, I felt it showed up more clearly and well-defined on the WJ-III than on the WISC.
Re what's considered gifted on the SB vs WISC etc - I'm sorry I don't have the direct link, but I think that there is an article on Hoagies that gives a breakdown for each IQ test with ranges for moderately vs highly vs profoundly etc. You can also see what Davidson considers the 99.9th mark as a comparison if you look at the DYS qualifying criteria page here.
