Which disabilities were less than 1% of disabled students eligible for?

• A. Visual impairment; Deaf-Blindness; Traumatic Brain Injury
• B. Specific Learning Disability; Health Impairment; Autism
• C. Hearing impairment; Orthopedic impairment; Developmental delay
• D. Autism; Emotional Disturbance; Intellectual Disability

Answer: (A)

Disability categories under IDEA vary widely in how many students they include. Vision impairment (including blindness) is relatively rare, deaf-blindness is extremely rare, and traumatic brain injury (TBI) is also a small portion of the population identified for special education. Because these conditions are uncommon, each tends to account for less than 1% of students with disabilities. In contrast, many other categories—like learning disabilities or autism—have much higher prevalence. So the combination of visual impairment, deaf-blindness, and traumatic brain injury being under 1% reflects how infrequent these specific disabilities are among those receiving special education services.
