Per the Texas Education Agency Dyslexia Handbook (revised 2019), Dyslexia means a disorder of constitutional origin manifested by a difficulty in learning to read, write, or spell, despite conventional instruction, adequate intelligence, and sociocultural opportunity (TEX Section 38.003(d)(1)-(2)).

The identification and intervention process for dyslexia can be multifaceted. These processes involve both state and federal requirements that must be followed. The evaluation, identification, and provision of services for dyslexic students are guided by both the Individuals with Disability Act (IDEA) and Section 504 Rehabilitation Act of 1973.
