About Dyslexia

Dyslexia is a specific learning disorder that is neurological in origin and that is characterized by unexpected difficulties with accurate or fluent word recognition and by poor spelling and decoding abilities that are not consistent with the person's intelligence, motivation, and sensory capabilities. These difficulties typically result from a deficit in the phonological components of language that is often unexpected in relation to other cognitive abilities. Secondary consequences may include problems in reading comprehension and reduced reading experience that can impede growth of vocabulary and background knowledge. (E2SSB 6162)

This definition of dyslexia is adopted by the 65th WA State Legislature, 2018 Regular Session.
