Thanks for these insights, aeh. The good news is that his scores are high enough that he qualifies for just about everything including DYS. We won't need to re-test.
The psych mentioned possible ADHD so perhaps that could be the source of the EF deficit. He also may have some sort of verbal processing deficit, again no diagnosis. I guess it makes sense that these could be related to the scatter. Not sure if its worthwhile to pursue additional expensive testing related to these issues.
The scattered performance also happen at school and has made advocacy hard. Teachers assume that because he sometimes gets easy questions wrong (or, more commonly, refuses to answer) that he is not in need of more challenging work.
