I have an 8yr old boy who writes his numbers and letter backward. He has some trouble reading and alot of trouble writing. He was tested for Dyslexia and he didn't fall in the range for it. I have asked the school to do more testing and they have all these guild lines they have to do before they will do farther testing. I'm wondering if there is another learn issue that could cause him to continue to write his letters and numbers backwards.
