Just to clarify, while I agree that the GAI is probably a more accurate representation of a child's potential intelligence, doesn't the FSIQ have some role to play with non 2e kids in determining how easy it is for kids to display their full potential? Particularly in being able to work at higher levels at a speed that doesn't require extra support.
I'm just curious as I only have a FSIQ as a percentage so I'm not able to calculate the GAI anyway (I don't think). I just haven't heard that "most" professionals think GAI is a better indicator, having said that my research is limited to several professionals. rather than most.
