3.2 Characteristics Across Exceptionality Categories

Characteristics Across Exceptionality Categories

Quick Answer: Each IDEA disability category is associated with a recognizable cluster of instructional, behavioral, or communication characteristics — but characteristics vary widely within a category, and no single characteristic diagnoses or disqualifies a student. The FTCE tests whether candidates can match a classroom scenario to the most likely underlying pattern of need and select an instructionally appropriate response, not just recite a checklist.

Knowing characteristics matters because they drive instructional decisions long before (and long after) a formal label is applied through evaluation. A teacher who recognizes a characteristic pattern early can request appropriate MTSS supports, communicate clearly with the ESE team, and adjust instruction while the eligibility process unfolds.

High-Incidence Categories: Academic and Attentional Patterns

Specific Learning Disability (SLD). Students with SLD typically show an unexpected gap between cognitive ability and achievement in a specific area — reading (dyslexia-type patterns), written expression (dysgraphia-type patterns), or math (dyscalculia-type patterns) — despite adequate classroom instruction. Common classroom signs: slow, effortful decoding; strong listening comprehension paired with weak reading comprehension; difficulty with math fact retrieval despite understanding concepts; inconsistent performance that doesn't match effort.

Other Health Impairment (OHI). Because OHI is a broad medical umbrella (ADHD, epilepsy, asthma, diabetes, sickle cell, and other chronic conditions), characteristics vary by condition. ADHD-related OHI commonly presents as difficulty sustaining attention, impulsivity, inconsistent work completion, and organizational challenges. Health-condition-related OHI (e.g., frequent absences from a chronic illness) may present as gaps in continuity of instruction requiring flexible pacing and health-care plan coordination.

Speech or Language Impairment. Characteristics include difficulty with articulation (sound production), fluency (stuttering), voice, or language (understanding or using vocabulary, grammar, or social language/pragmatics). Because language underlies literacy, a language impairment can also depress reading and writing performance — a frequent overlap the FTCE probes.

Emotional/Behavioral Disability (ED/EBD). Characteristics must be evident over a long period and to a marked degree — not a single bad day. Patterns include difficulty building or maintaining relationships, inappropriate behaviors or feelings under normal circumstances, a pervasive mood of unhappiness or depression, or physical symptoms/fears associated with personal or school problems. A key instructional distinction: ED/EBD is about the degree, duration, and pervasiveness of the pattern, not the presence of occasional misbehavior.

Autism Spectrum Disorder: A Spectrum, Not a Single Profile

Autism characteristics cluster in two core domains: (1) differences in social communication and social interaction (e.g., reduced eye contact, difficulty with reciprocal conversation, challenges reading nonverbal cues), and (2) restricted or repetitive patterns of behavior, interests, or activities (e.g., insistence on sameness, intense narrow interests, sensory sensitivities, repetitive motor movements). Because autism is a spectrum, presentation ranges from students who need intensive, highly structured supports to students with strong academic skills who primarily need social-communication and executive-functioning supports. Comorbid intellectual disability, ADHD, anxiety, and communication disorders are common and must be considered together, not treated as separate unrelated issues.

Intellectual Disability: Two Concurrent Domains

Intellectual disability requires deficits in both general intellectual functioning (typically reflected in standardized cognitive assessment) and adaptive behavior (conceptual, social, and practical skills needed for everyday life), with onset during the developmental period. Classroom characteristics include slower rate of learning new skills, difficulty generalizing skills across settings, and need for more repetition, concrete examples, and explicit instruction in both academic and functional/life skills. Severity ranges widely, which affects how much instructional time is spent on academic content versus functional/independent living skills.

Low-Incidence Categories: Specialized Access Needs

Comorbidity: The Rule, Not the Exception

Comorbidity — the co-occurrence of two or more conditions — is common across categories: SLD often overlaps with attention difficulties; autism often overlaps with intellectual disability, anxiety, or communication disorders; ED/EBD often overlaps with trauma histories or ADHD. FTCE scenario items often describe a student with characteristics spanning two categories specifically to test whether candidates recommend a full, individualized evaluation covering all suspected areas of need rather than anchoring on the first characteristic mentioned.

Instructional Takeaway

Characteristics inform instructional hypotheses and progress-monitoring focus, but characteristics are a starting point for referral and evaluation — never a substitute for the legal eligibility process described in Section 3.1. A teacher who notices a characteristic pattern should document specific, objective, data-based observations (work samples, frequency counts, running records) and route them through the school's MTSS/child study process rather than assigning an informal label.
