The Individuals with Disabilities Education Act (IDEA) is a federal law that guarantees a free, appropriate public education (FAPE) to eligible children with disabilities, including those with visual impairments. IDEA ensures the provision of special education and related services across the United States and defines how states and public agencies serve these students.

​IDEA Overview

IDEA has two main parts related to age:
  • Part C: For infants and toddlers (birth through age 2) and their families, providing early intervention services.
  • Part B: For children and youth (ages 3–21), providing special education and related services in public school settings.

​Definition of Visual Impairment under IDEA

​Under Part B, a child may qualify for services under the eligibility category of "Visual Impairment, including Blindness", defined as:
“An impairment in vision that, even with correction, adversely affects a child’s educational performance. The term includes both partial sight and blindness.”
Important Clarification:
In a May 22, 2017, memorandum, the U.S. Department of Education clarified that the IDEA definition does not include a severity modifier—meaning any vision impairment, regardless of visual acuity or severity, must be considered under this eligibility category if it adversely impacts educational performance.

Eligibility Determination Process

​Before services are provided, a full and individual evaluation must be conducted to:
  1. Determine whether the child has a disability.
  2. Identify the extent of the child’s educational needs.
Eligibility for visual impairment must be based on multiple sources of information. This includes, but is not limited to:
  • A recent eye medical report
  • A Functional Vision Evaluation (FVE)
  • A Learning Media Assessment (LMA)
  • Additional evaluations if determined necessary by the team.
No single assessment tool may be used as the sole criterion for eligibility.

Expanded Core Curriculum (ECC) and Educational Need

​A key component of eligibility for students with visual impairments includes educational needs related to vision loss, particularly in the Expanded Core Curriculum (ECC). While many students benefit from ECC instruction (e.g., in independent living or social skills), students with visual impairments require ECC instruction delivered differently—often directly taught by a Teacher of Students with Visual Impairments (TVI)—because their vision loss impacts how they access and learn these skills.

​Key Takeaways

  • IDEA ensures access to services for students with visual impairments.
  • Any level of visual impairment must be considered if it affects educational performance.
  • A thorough evaluation—including eye report, FVE, and LMA—is essential.
  • ECC areas must be assessed and addressed through specialized instruction.
