Not a Guru by any stretch of the word!
The GAI would be about the same as the FSIQ. It wouldn't make a diference in this case. Typically GAI would be calculated with significant index differences.
What age was the first IQ test? What was the reason for the second test?
I know this isn't a popular view around here, but I have seen a few local kids drop dramatically after early testing. It's one of the reasons my district doesn't want to look at testing before 6 or later.
OTH, I have also seen kids that just don't seem to test well ever despite all sorts of evidence to the contrary. Did the tester give any additional information about what was happening during BD? That is the one score that rally stands out as odd or problematic.
