What is Dyslexia?

The diagnosis is clinical.
The treatment is educational.
The understanding is scientific.

~M. Rawson

Dyslexia presents with different degrees of severity and is often accompanied by unique strengths and talents.


Dyslexia is a specific learning disability that is neurobiological 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 the growth of vocabulary and background knowledge.

Annals of Dyslexia, 2003 (53)

“Neil is a different boy from a year ago, not only because his reading is starting to come along, but because he is enjoying school and, once again, believes he can learn and succeed. Honestly, the Claremont School has been a god-send for Neil.”

A warm and exceptional teacher, Evelyn provided a wonderful overview of the Orton-Gillingham approach in her Associate Level course. I consider it a privilege to have been her student.
