I have a learned a lot this week. DGS6 is a visual-spatial learner, and his processing speed is partly that and maybe an auditory processing thing. He is also being evaluated for a possible obstructive sleep apnea, which can cause all of his symptoms, including and especially the way below normal information score on the test.

I did not know bedwetting was associated strongly with ADHD, dyslexia and OSA in children. I happened upon an article by chance and now know this may be a strong clue as to why his scores are what they are.

herenow - Several testers have said they can administer the WISC-IV, but I think the SB5 is probably the best with his processing speed, but we may go ahead with the WJ-III. Nothing is for sure until we get the possible medical issues dealt with.

Thanks for all your replies.
