Understanding Students with Disabilities and Their Learning Characteristics
This domain tests whether you can describe the learning profile behind a disability label and distinguish it from other explanations for the same behavior, including language difference, cultural difference, and lack of instruction.
High-incidence and low-incidence profiles
- Specific learning disability: a processing deficit affecting reading, writing, or math in a student with otherwise adequate ability; dyslexia centers on word-level decoding and phonological awareness, dyscalculia on number sense, dysgraphia on transcription.
- ADHD is not an IDEA category; students are typically served under other health impairment or Section 504.
- Autism: persistent differences in social communication plus restricted, repetitive behavior or sensory reactivity; intellectual disability is not implied.
- Intellectual disability: significantly subaverage intellectual functioning together with deficits in adaptive behavior, both present during development.
- Emotional disturbance: chronic, severe internalizing or externalizing patterns that harm educational performance; socially maladjusted students are excluded.
- Also know deaf/hard of hearing, blind/visually impaired, orthopedic impairment, traumatic brain injury, multiple disabilities, speech-language impairment.
Language difference versus disability
Second-language learners pass through a silent period and acquire conversational fluency (BICS) before academic language (CALP). True disability shows up in the native language too, persists across settings, and does not resolve with good instruction. Evaluate in the dominant language and compare with true peers.
Worked example
A kindergarten teacher reports that a Spanish-speaking child 'does not know letters.' Before referral, the team should document instruction, screen in Spanish, compare with bilingual peers, and rule out attendance and hearing issues. If the pattern appears in both languages and resists targeted intervention, a referral is warranted.
Traps
Listing ADHD as an IDEA category; equating autism with intellectual disability; calling cultural or language differences a disability; assuming every student with a learning disability has a low IQ.
