My 6-year-old son was evaluated in 2007 by a neuropsychologist. She determined that he does have the precursors for dyslexia and what appeared to be the beginnings of it. I then had him evaluated for dyslexia and pre-screened for the Barton Reading and Spelling System. He is very intelligent and is reading above grade level. He can write, but it takes him time. His school refuses to believe he has dyslexia.
Where can I find more information to prove he has dyslexia even though he can read and write?
Your child was tested when he was in preschool. The results were based on levels of expected performance for that age. It may be that what was seen as a weakness then (precursor), improved with maturation and is not an issue now. You say he can read and write at grade level. So, he does not appear to have any deficits that might suggest dyslexia at this time.
It is difficult to use these data to assess if he has learning disabilities. I suggest that you stop pushing for a diagnosis (dyslexia) and ask the school to help clarify if he has any problems at this time.
