Dyslexia is a specific learning disability that is neurological in origin. It is characterized by difficulties with accurate/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.

Adopted by the IDA Board, November 12, 2002

New  House Bill 3928

House Bill 3928 was passed by the 88th Texas Legislature (Regular Session) and impacts dyslexia evaluation, identification, and instruction. While the Texas Education Agency works to update the necessary materials, be aware that the law is effective immediately. The State Board of Education's proposed timeline for its required changes will be communicated as that timeline is determined and communicated to the agency. The Texas Education Agency has created resources to assist with the implementation of HB 3928 and the most updated information is available on the Texas Education Agency's Dyslexia and Related Disorders website:
