Understanding Students with Disabilities
Understanding Students with Disabilities
This domain tests whether you can recognize IDEA disability categories, distinguish disability from other explanations for low achievement, and explain how characteristics affect learning. Expect items on child find, eligibility, high- versus low-incidence disabilities, and the exclusionary factors that prevent misidentification.
Core rules and concepts
- IDEA recognizes 13 categories, including specific learning disability, speech or language impairment, other health impairment, emotional disturbance, autism, intellectual disability, hearing impairment, visual impairment, deaf-blindness, orthopedic impairment, traumatic brain injury, multiple disabilities, and developmental delay where the state uses it.
- Eligibility requires a disability, an adverse educational impact, and a need for specially designed instruction. A medical diagnosis alone does not guarantee an IEP.
- Child find requires districts to identify, locate, and evaluate all children suspected of having a disability, including homeless, foster, and parentally placed private school children.
- For specific learning disability, teams must consider exclusionary factors: lack of appropriate reading or math instruction, limited English proficiency, cultural factors, and environmental or economic disadvantage. These cannot be the determinant factor.
- High-incidence disabilities include SLD, speech/language impairment, other health impairment, and emotional disturbance; low-incidence include deaf-blindness, significant sensory or cognitive disabilities, and multiple disabilities.
Worked example
A second grader reads below grade level. The team reviews attendance, vision and hearing screening, home language survey, and Tier 2 intervention progress. The student received 10 weeks of explicit phonics intervention with fidelity and made minimal progress; English proficiency is adequate; instruction was appropriate. Because the exclusionary factors are ruled out and the student shows an adverse educational impact, the team proceeds with a comprehensive evaluation for SLD using multiple measures. Reasoning: low achievement alone is not a disability; the team must document inadequate response and rule out other causes.
Traps that cost marks
Equating ADHD, dyslexia, or a medical diagnosis with automatic IEP eligibility; skipping exclusionary factors and overidentifying English learners; confusing Section 504 access supports with IDEA specially designed instruction; assuming a student in Tier 3 automatically needs an IEP.
