Thanks everyone. I appreciate all of your responses.
DS's lowest subtest scores were in working memory and processing speed. However, he got 95% in symbol search and 84% in block design. She said he was really slow with block design.
She did Beery too. I know nothing about this test, so let me know if more information would be helpful. He got Average in VMI and Motor Coordination and High in Visual Perception. I need to research this some more-we spent very little time discussing this.
I'm certainly not going to rule out vision issues, but I'm having a hard time making sense of this in light of his scores.
