carmsquestion_edited.jpg

Intellectual Disability describes "significantly sub-average general intellectual functioning, existing concurrently with deficits in adaptive behavior and manifested during the developmental period, that adversely affects a child's educational performance" (Gargiulo & Bouck, 2018, p. 591).

Social 
  •  Difficulty understanding social rules

  • Difficulty understanding the consequences of their actions

  • Difficulty with communication due to speech or language impairments

  •  Artistic

  • Creative

  • Resilient

  • Certain conditions that cause Intellectual Disability are correlated with friendliness and positive outlook:

    • Down's Syndrome

    •  Williams Syndrome

    •  Willi-Prader Syndrome 

Strengths
Academic
  • Difficulty understanding abstract ideas

  • Impaired reasoning and problem-solving abilities

  • Difficulty learning from experience

  • Difficulty understanding cause and effect

  • Slow processing speed

Physical
  • Delayed or impaired physical development 

  • Deficits in fine and gross motor skills

  • Poor prioperception

Affective

  • May have socially inappropriate facial expressions or verbalizations in response to stimuli

  • Disability may affect physical characteristics if caused by a congenital syndrome

  • Disability may be causes by a disorder that impairs motor function, resulting in difficulty controlling facial muscles

Cognitive
  • IQ score below 70

  • Significant deficits in functional and adaptive skills

  • High incidence of co-morbid disabilities

Levels of Severity
  • People with Intellectual Disability (ID), can have mild, moderate, severe, or profound ID.

  • The greatest percentage of people with ID are diagnosed with a mild form. Mild ID presents in slower cognitive functioning, but they are able to learn strategies to help them adapt to daily life with minimal supports.

  • People with Moderate ID can learn functional strategies, but need moderate support.

  • People with severe ID have significant developmental delays and difficulty communicating. Due to their level of disability, people with sever ID need supervision and home care.  

  • People with profound ID have severe congenital syndromes that impair communication, physical and cognitive functioning. These individuals must live in a setting that provides constant supervision and help with basic self-care.

 

Incidence

  • It is estimated that 6% of K-12 students who qualify for services have an Intellectual Disability (ID).

Educational
Implications
  • 50% of students with ID spend 40% or less of their school day in a mainstream classroom.

  • Students with ID learn best when information is broken down into small segments.

  • Reteaching items frequently, and using varied educational strategies, can help those with ID retain information.
