What Is a Learning Disability?
A learning disability is not a measure of intelligence. It is a difference in how the brain processes information, and IDEA gives children with learning disabilities specific rights.
How IDEA Defines Specific Learning Disability
Under the Individuals with Disabilities Education Act, Specific Learning Disability (SLD) is defined as a disorder in one or more of the basic psychological processes involved in understanding or using language, spoken or written, that may manifest itself in the imperfect ability to listen, think, speak, read, write, spell, or do mathematical calculations.
The definition includes conditions such as:
- Dyslexia: Difficulty with accurate and fluent word reading, phonological processing, and spelling
- Dyscalculia: Difficulty with number sense, arithmetic, and mathematical reasoning
- Dysgraphia: Difficulty with handwriting, spelling, and written expression
- Auditory processing disorder: Difficulty processing what is heard despite normal hearing
- Nonverbal learning disability: Difficulty with visual-spatial tasks, math, and social cues
- Oral and written language learning disability: Difficulty with reading comprehension and written expression
The definition explicitly excludes learning problems that result primarily from visual, hearing, or motor disabilities; intellectual disability; emotional disturbance; or environmental, cultural, or economic disadvantage.
How Schools Evaluate for Learning Disabilities
There is no single test for a learning disability. Schools use one of two approaches, or a combination:
Discrepancy Model: The traditional approach compares a child's IQ score to their academic achievement scores. A significant gap between the two (the discrepancy) was historically used to identify an SLD. Many states still use this model.
Response to Intervention (RTI) or Multi-Tiered System of Supports (MTSS): This approach evaluates whether the child has responded to scientific, research-based interventions. If a child fails to respond to increasingly intensive interventions, that pattern of inadequate response becomes part of the eligibility determination. Many states now allow or require this approach.
A comprehensive evaluation for SLD typically includes norm-referenced academic achievement tests, cognitive assessments, processing measures (phonological processing, working memory, processing speed), classroom observation, and review of existing data including grades and intervention records.
The Three-Part Eligibility Test
Having a learning disability does not automatically qualify a child for special education. Three conditions must all be true:
- The child has a specific learning disability as defined by IDEA
- The disability adversely affects educational performance
- The child needs special education as a result
If a child is struggling but making adequate progress with general education supports, the school may determine that special education is not needed. This is where many families disagree with their schools. If your child is working extremely hard to maintain average grades but falling apart at home, that effort cost is relevant data, even if grades look okay on paper.
What Special Education Looks Like for Students with Learning Disabilities
Most students with specific learning disabilities spend most of their day in general education classes with supports. Services commonly include:
- Specialized reading instruction (often based on structured literacy or Orton-Gillingham approaches for dyslexia)
- Resource room or pull-out instruction in specific subject areas
- Accommodations such as extended time, text-to-speech, graphic organizers, and reduced written output requirements
- Related services such as speech-language therapy if there are language processing components
Learning Disability vs. Intellectual Disability
These are distinct conditions. A specific learning disability affects one or more narrow processing areas while overall intellectual functioning is in the average range or above. An intellectual disability involves significantly below-average intellectual functioning across many domains and deficits in adaptive behavior.
A child can have both a specific learning disability and an intellectual disability, but they require separate evaluation and have different eligibility criteria. If you believe your child has both, make sure the evaluation addresses both possibilities.
