My kid was also tested with slow processing speed. At school and although he is only in K, they are addressing this issue is an odd way. I don't know if it is effective yet. They are teaching him how to write in cursive because cursive is supposed to be faster than print. At first, I was just wondering why they were torturing my child with more fine motor skills. But, they had a reason and claim that it has worked with other children. I'm anxiously waiting to see.

Good luck.
