1. Autism
2. Deaf-Blindness
3. Deafness
4. Emotional Disturbance (ED)
5. Hearing Impairment
6. Intellectual Disability (ID)
7. Multiple Disabilities
8. Orthopedic Impairment
9. Other Health Impairment (OHI)
10. Specific Learning Disability (SLD)
11. Speech or Language Impairment (SLI)
12. Traumatic Brain Injury (TBI)
13. Visual Impairment Including Blindness

Key Eligibility Considerations
IDEA requires that a student meet two criteria to qualify for special education services: they must be identified with a disability under one of the 13 eligibility categories, and they must require specially designed instruction to access and benefit from education (IDEA, 2004). The evaluation process should include data from multiple sources, such as classroom observations, academic performance, standardized assessments, and family input (Bryant, Smith, & Bryant, 2024). Equity and ethical practice are essential to this process—educators must use culturally responsive tools and consider how 2E (twice-exceptional) and ELL (English Language Learner) students may present differently (Blanck, 2019). Teams should work collaboratively with families and specialists to ensure accurate, fair eligibility decisions that reflect IDEA’s goal of supporting all learners in the least restrictive environment (Bryant et al., 2024).
From Referral to Evaluation Under IDEA
The process of identifying students with exceptionalities under IDEA begins with a referral based on concerns related to learning, behavior, or development. Referrals may come from educators, parents, or other school personnel and lead to a review of relevant classroom data and observations (Bryant, Smith, & Bryant, 2024). Upon receiving parental consent, the school must complete a comprehensive evaluation within 60 days, using both standardized assessments and classroom performance data to determine whether the student meets eligibility criteria under IDEA (Individuals with Disabilities Education Act, 2004). If the student qualifies, a multidisciplinary team—including educators, service providers, and the student’s family—collaborates to develop an Individualized Education Program (IEP) (Bryant et al., 2024). This plan outlines specific goals, services, and accommodations to ensure success in the least restrictive environment. Throughout the process, teams must remain vigilant in eliminating bias, especially for students from culturally and linguistically diverse backgrounds, by promoting inclusive practices and ensuring equitable access to support (Blanck, 2019).
