DD had a low processing speed score on the WISC. Actually it was in the average range but below 100 and there was a large gap between that and her other scores. The coding section, esp. (where kids are asked to copy symbols from a key) was really hard for her. The teacher sees the same thing in class. She is excessively slow with written work, even though it looks like she is focused. It could be dysgraphia, or simply ADHD and not staying mentally focused, or perfectionism, or fine motor issues, or visual-motor issues, or a combination of all of those things.
My ds12 is similar. There is a huge discrepancy between what he is capable of communicating either orally or using a computer than what he is able to write by hand. His handwritten work looks like it was written by a much younger student than his typed work.
I haven't done anything about it partly because he doesn't want to draw attention to himself in that way (he is completely resistant to investigating) and partly because his tester thought it was due to perfectionism (I don't believe that's the whole picture) and partly because getting accommodations for it might be a battle considering "he's doing fine", even with a skip.
