I can only say from my personal experience since I haven't studied both tests carefully. DS7 scored nearly identical on the SB5 as on the WISC. However, with GAI on the WISC and extended norms, I think we have a more accurate picture of the type of student that he is in school. He is extremely verbal (which was rewarded on the WISC) but petrified of timed testing (rewarded on the SB5). He is very logical and thoughtful (rewarded on the SB5) and full of random information (rewarded on the WISC).

I will say that his scores on the SB5 did not *quite* qualify him for DYS but his scores on the WISC using GAI put him comfortably in the range.
