"As a result of extraordinary scientific progress, reading and dyslexia are no longer a mystery; we now know what to do to ensure that each child becomes a good reader and how to help readers of all ages and at all levels."--Sally Shaywitz, M.D.

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 (International Dyslexia Association, 2002).
