Definition of Dyslexia
The Texas Education Code (TEC)-38.003 defines dyslexia in the following way:
(1) Dyslexia means a disorder of constitutional origin manifested by a difficulty in learning to read, write, or spell, despite conventional instruction, adequate intelligence and socio-cultural opportunity.
(2) Related disorders includes disorders similar to or related to dyslexia such as developmental auditory imperception, dyspahsia, specific developmental dyslexia, developmental dysgraphia, and developmental spelling disability.
The current definition from the International Dyslexia Association states the following:
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.
