Understanding Students with Disabilities
Domain 1: Understanding Students with Disabilities
This domain tests whether you can recognize disability characteristics, apply legal foundations, and explain how disabilities affect learning. Minnesota uses the IDEA disability categories and requires that eligibility rest on three findings, not a diagnosis alone: (1) the student has a disability, (2) the disability has an adverse effect on educational performance, and (3) the student needs specially designed instruction.
Core rules
- IDEA lists 13 categories: autism, deaf-blindness, deafness, emotional disturbance, hearing impairment, intellectual disability, multiple disabilities, orthopedic impairment, other health impairment (OHI), specific learning disability, speech or language impairment, traumatic brain injury, and visual impairment including blindness.
- Section 504 is broader: a physical or mental impairment that substantially limits a major life activity. It can require accommodations but does not require specially designed instruction.
- High-incidence categories (SLD, speech/language, OHI) are common; low-incidence categories are rarer and often require specialized supports.
- Disability labels describe eligibility, not instruction. Plan from the student's present levels.
Worked example
A 9-year-old with ADHD is struggling to finish assignments. ADHD alone does not create IDEA eligibility. The team must ask whether ADHD is an OHI that adversely affects educational performance and whether specialized instruction is needed. If the student needs only extra time and a quiet setting, Section 504 may be appropriate. If the student needs explicit organization instruction and modified assignments, an IEP may be appropriate. Reasoning: the legal question is impact and need, not the diagnosis.
Traps
- Treating a medical diagnosis as automatic IDEA eligibility.
- Confusing 504 accommodations with IEP services.
- Overlooking the adverse-effect and need prongs.
- Assuming a student with a disability always needs a separate setting; LRE presumes general education with supports.
