OSPI uses the definition of dyslexia adopted by the National Institute of Child Health and Human Development (NICHD) and the International Dyslexia Association (IDA) in 2002:
Dyslexia is a specific learning disability that is neurological in origin. It
is characterized by difficulties with accurate and /or fluent word recognition
and by poor spelling and decoding abilities. These difficulties typically result
from a deficit in the phonological component of language that is often
unexpected in relation to other cognitive abilities and the provision of
effective classroom instruction. Secondary consequences may include problems in
reading comprehension and reduced reading experience that can impede growth of
vocabulary and background knowledge.
From 2005 to 2011, the Washington State Legislature provided funding for the Lorraine Wojahn Dyslexia Pilot Reading Program to support services to children affected by dyslexia. Download the 2011 report to the Legislature:
