Development and Characteristics of Learners
Development and disability
Candidates must distinguish typical developmental sequences (cognitive, language, motor, social-emotional, adaptive) from atypical patterns, and know the IDEA categories and their hallmark characteristics. Learning disabilities (including dyslexia, dyscalculia, dysgraphia) involve processing deficits and unexpected underachievement; intellectual disability combines significantly subaverage intellectual functioning with adaptive deficits and onset before 18; autism spectrum disorder involves social communication and restricted/repetitive behavior; emotional disturbance includes inability to learn unexplained by other factors, relationship problems, inappropriate behavior, unhappiness or depression, and physical symptoms or fears. ADHD is not an IDEA category-it is usually served under other health impairment.
Traps
Questions often confuse ADHD with a specific learning disability, call a language difference a language disorder, or forget that eligibility requires adverse educational impact. Twice-exceptional students can be missed when strong scores mask a disability.
Culture and context
Disproportionality, assessment bias, second-language acquisition, and poverty all affect referral decisions. Rule out lack of appropriate instruction and limited English proficiency before identifying a disability.
Worked example
An English learner reads below grade level. Do not compare to monolingual norms alone; gather native-language data, check schooling history, and observe across settings. If difficulties persist in both languages after targeted support, a disability is more plausible.
Rule of thumb
Describe functioning in observable, setting-specific terms; a label is not an intervention.
