Does Special Education law include dyslexia?


Parents and educators often ask if dyslexia is included in the Individuals with Disabilities Education Improvement Act (IDEA, 2004), the federal special education law, and if the word dyslexia can be used in an IDEA evaluation, eligibility determinations, or individualized education program (IEP) documents.

The answer is yes.

Dyslexia is a condition that could qualify a child as having a specific learning disability under the IDEA. There is nothing in the IDEA that would prohibit the use of the term dyslexia in IDEA evaluation, eligibility determinations, or IEP documents. Further, State and Local Education Agencies cannot prohibit the use of the term dyslexia in evaluations, eligibility, and IEP documents.

The IDEA and its implementing regulation contain a list of conditions under the definition ‘specific learning disability,’ also known as SLD.  This list includes dyslexia.

The definition of specific learning disability from U.S. federal special education law is:

“(A) In general

The term ‘specific learning disability’ means a disorder in 1 or more of the basic psychological processes involved in understanding or in using language, spoken or written, which disorder may manifest itself in the imperfect ability to listen, think, speak, read, write, spell, or do mathematical calculations.

(B) Disorders included

Such term includes such conditions as perceptual disabilities, brain injury, minimal brain dysfunction, dyslexia, and developmental aphasia.

(C) Disorders not included

Such term does not include a learning problem that is primarily the result of visual, hearing, or motor disabilities, of mental retardation, of emotional disturbance, or of environmental, cultural, or economic disadvantage.”

Data show that specific learning disabilities, called SLD, are the most common special education category; specifically, about 40% of all special education students in the U.S. are identified as having a SLD (U.S. Department of Education, 2017).  Of those identified with a SLD, approximately 80% have dyslexia or a specific learning disability in reading (Shaywitz, 1998). It’s clear that dyslexia is very common.

If a child’s dyslexia is the condition that forms the basis for the determination of a specific learning disability, the child’s IEP could include specific instructional supports, accommodations, and modifications proven effective for addressing the unique educational needs resulting from dyslexia.

Federal guidance reminds us that parents can request an initial evaluation at any time to determine if a child has a disability including dyslexia.
