Characteristics of Students with Disabilities
Learning Disabilities
Learning disabilities are neurologically-based processing disorders that affect specific academic skills despite average or above-average intelligence.
Characteristics of Specific Learning Disabilities
Reading disabilities (dyslexia) involve difficulties with accurate and fluent word recognition, decoding, and spelling. Phonological processing deficits underlie most reading disabilities. Students may struggle with phonemic awareness, letter-sound correspondence, and reading fluency. Comprehension may be affected secondarily due to decoding difficulties.
Written expression disabilities involve difficulties with handwriting, spelling, and composition. Students may have trouble organizing ideas, generating text, and revising written work. Mechanical errors in spelling, punctuation, and grammar are common.
Mathematics disabilities (dyscalculia) involve difficulties with number sense, mathematical reasoning, and calculation. Students may struggle with math facts, place value concepts, and problem-solving procedures. Spatial aspects of mathematics may also be affected.
Educational Implications
Students with learning disabilities benefit from explicit, systematic instruction in deficit areas. Multisensory approaches strengthen learning. Accommodations such as extended time, assistive technology, and alternative formats support access to curriculum. Self-advocacy skills help students understand and communicate their needs.
Intellectual Disabilities
Intellectual disabilities are characterized by significant limitations in intellectual functioning and adaptive behavior originating before age 22.
Characteristics by Severity Level
Educational Implications
Functional curriculum emphasizes practical life skills. Systematic instruction with task analysis breaks skills into teachable steps. Community-based instruction promotes generalization. Person-centered planning ensures meaningful goals. Transition planning begins early and focuses on adult outcomes.
Emotional and Behavioral Disorders
Emotional and behavioral disorders involve patterns of behavior that adversely affect educational performance.
Internalizing Behaviors
Anxiety disorders involve excessive worry, fear, and avoidance. Physical symptoms such as stomachaches and headaches may occur. Social anxiety affects peer relationships and classroom participation. Selective mutism involves failure to speak in specific social situations despite speaking in others.
Depression involves persistent sad mood, loss of interest, and changes in sleep, appetite, and energy. Academic performance may decline. Social withdrawal is common. Suicidal ideation requires immediate intervention.
Externalizing Behaviors
Oppositional defiant disorder involves a pattern of angry, irritable mood and argumentative, defiant behavior. Students frequently lose their temper and argue with adults. Deliberately annoying others and blaming others for mistakes are common.
Conduct disorder involves serious violations of rules and the rights of others. Aggression toward people and animals may occur. Property destruction, deceitfulness, and serious rule violations are characteristic.
Educational Implications
Positive behavioral interventions and supports establish clear expectations and reinforce appropriate behavior. Functional behavior assessment identifies the purposes of challenging behaviors. Behavior intervention plans address underlying functions. Social-emotional learning programs teach emotional regulation and social skills. Collaboration with mental health professionals supports comprehensive intervention.
Autism Spectrum Disorder
Autism spectrum disorder is characterized by persistent deficits in social communication and restricted, repetitive patterns of behavior, interests, or activities.
Social Communication Characteristics
Deficits in social-emotional reciprocity range from abnormal social approach to reduced sharing of interests and emotions. Nonverbal communication difficulties include abnormalities in eye contact, body language, and use of gestures. Difficulty developing, maintaining, and understanding relationships is common.
Restricted, Repetitive Behaviors
Stereotyped or repetitive motor movements, use of objects, or speech include hand flapping, lining up objects, and echolalia. Insistence on sameness and inflexible adherence to routines is common. Highly restricted, fixated interests may be abnormal in intensity or focus. Hyper- or hyporeactivity to sensory input affects daily functioning.
Educational Implications
Structured, predictable environments reduce anxiety and support learning. Visual supports including schedules, social stories, and visual cues enhance comprehension. Social skills instruction addresses core deficits. Applied behavior analysis principles inform effective instruction. Sensory considerations are incorporated into classroom design. Communication supports range from augmentative systems to pragmatic language intervention.
Attention-Deficit/Hyperactivity Disorder
ADHD is characterized by persistent patterns of inattention and/or hyperactivity-impulsivity that interfere with functioning.
Inattention Characteristics
Difficulty sustaining attention in tasks affects academic performance. Failure to attend to details results in careless errors. Difficulty following through on instructions and completing tasks is common. Organizational difficulties affect academic and daily functioning. Avoidance of tasks requiring sustained mental effort is typical. Frequently losing necessary items and being easily distracted interfere with productivity. Forgetfulness in daily activities is common.
Hyperactivity-Impulsivity Characteristics
Fidgeting, squirming, and leaving seat when remaining seated is expected occur frequently. Running and climbing in inappropriate situations or feelings of restlessness are common. Difficulty engaging in leisure activities quietly and talking excessively are typical. Blurting out answers, difficulty waiting turn, and interrupting others reflect impulsivity.
Educational Implications
Environmental modifications reduce distractions and support attention. Organizational supports including checklists, planners, and routines improve task completion. Movement opportunities provide appropriate outlets for hyperactivity. Behavioral interventions reinforce on-task behavior and task completion. Close home-school communication supports consistency. Medication management may be part of comprehensive treatment.
Communication Disorders
Communication disorders affect the ability to receive, send, process, and comprehend verbal, nonverbal, and graphic symbol systems.
Speech Disorders
Articulation disorders involve difficulty producing speech sounds correctly. Phonological disorders involve patterns of sound errors. Fluency disorders (stuttering) involve disruptions in the flow of speech. Voice disorders affect pitch, loudness, or quality.
Language Disorders
Receptive language disorders affect understanding of spoken or written language. Expressive language disorders affect producing language. Mixed receptive-expressive disorders affect both modalities. Pragmatic language disorders affect social use of language.
Educational Implications
Speech-language pathologists provide specialized intervention. Classroom accommodations support comprehension and expression. Augmentative and alternative communication systems may be needed. Language-rich environments support development. Collaboration between special educators and speech-language pathologists ensures coordinated services.
Sensory Impairments
Hearing Impairments
Hearing loss ranges from mild to profound. Conductive hearing loss involves the outer or middle ear. Sensorineural hearing loss involves the inner ear or auditory nerve. Mixed hearing loss involves both types.
Educational implications vary based on degree of loss and communication approach. Amplification devices including hearing aids and cochlear implants may be used. Communication approaches include oral/aural, total communication, and American Sign Language. Classroom accommodations address access to auditory information. Deaf culture and identity considerations are important.
Visual Impairments
Visual impairments range from low vision to total blindness. Functional vision assessment determines how students use remaining vision. Orientation and mobility instruction supports independent travel. Braille literacy is essential for students who are blind. Assistive technology provides access to print and visual information.
Deaf-Blindness
Combined hearing and vision loss creates unique educational challenges. Communication systems must be individualized. Tactile learning approaches are emphasized. Orientation and mobility require specialized instruction. Intervenor services may support communication and access.
Physical and Health Impairments
Orthopedic Impairments
Cerebral palsy is the most common orthopedic impairment. Spina bifida affects mobility and may include cognitive effects. Muscular dystrophy is a progressive condition affecting muscle function. Limb deficiencies may be congenital or acquired.
Educational implications include accessibility considerations, adaptive equipment, and accommodations for written work. Physical and occupational therapy support function. Assistive technology promotes independence.
Other Health Impairments
Chronic health conditions such as epilepsy, diabetes, and asthma require health management plans. Fatigue and absences may affect academic progress. Medication effects should be monitored. Emergency procedures must be in place.
Traumatic Brain Injury
Acquired brain injuries result in changes in cognition, behavior, and physical function. Effects vary widely based on injury location and severity. Recovery is ongoing but may plateau. Cognitive rehabilitation supports recovery and compensation.
Multiple Disabilities
Students with multiple disabilities have combinations of impairments that create unique educational needs. Functional curriculum and life skills instruction are typically emphasized. Specialized supports address each area of disability. Team collaboration is essential for comprehensive programming.
