Disability Categories
IDEA identifies 13 disability categories that may qualify a child for special education: autism, deaf-blindness, deafness, emotional disturbance, hearing impairment, intellectual disability, multiple disabilities, orthopedic impairment, other health impairment, specific learning disability, speech or language impairment, traumatic brain injury, and visual impairment.
Dyslexia
A specific learning disability that primarily affects reading and language processing. Children with dyslexia may struggle with reading fluency, decoding, spelling, and reading comprehension.
Evaluation
A comprehensive assessment to determine if your child has a disability and qualifies for special education. It looks at all areas of suspected disability and must use multiple methods, not just a single test.
SLD in context
Specific Learning Disability comes up across the IEP process — in your IEP document, during meeting prep, and in the federal rights that protect your child. IEP Ally explains where it shows up and what to do about it.
