5.6 Intellectual disabilities  (Page 3/2)

An intellectual disability is a significant limitation in a student’s cognitive functioning and daily adaptive behaviors (Schalock&Luckasson, 2004; American Association on Mental Retardation, 2002). The student may have limited language or impaired speech and may not perform well academically. Compared to students with learning disabilities discussed earlier, students with intellectual disabilities have impairments to learning that are broader and more significant. They score poorly on standardized tests of intelligence (like the ones discussed later, in [link] ). Everyday tasks that most people take for granted, like getting dressed or eating a meal, may be possible, but they may also take more time and effort than usual. Health and safety can sometimes be a concern (for example, knowing whether it is safe to cross a street). For older individuals, finding and keeping a job may require help from supportive others. The exact combination of challenges varies from one person to another, but it always (by definition) involves limitations in both intellectual and daily functioning.

As a teacher, you may hear more than one term for describing students with intellectual disabilities. If the disability is mild, teachers sometimes refer to a student with the disability simply as a slow learner , particularly if the student has no formal, special supports for the disability, such as a teaching assistant hired specifically to assist the student. If the disability is more marked, then the student is more likely to be referred to either as having an intellectual disability or as having mental retardation . In this chapter I primarily use the term intellectual disability , because it has fewer negative connotations while still describing one key educational aspect of the disability, cognitive impairment. Keep in mind, however, that actual intellectual disabilities are always more than cognitive: they also involve challenges about adapting to everyday living.

Levels of support for individuals with intellectual disabilities

Intellectual disabilities happen in different degrees or amounts, though most often are relatively mild. Traditionally the intensity or “amount” of the disability was defined by scores on a standardized test of scholastic aptitude (or “IQ test”), with lower scores indicating more severe disability. (More about these tests in [link] .) Because of the insensitivity of such tests to individuals’ daily social functioning, however, current trends are toward defining intensities by the amount of support needed by the individual. [link] summarizes the most commonly used scheme for this purpose, one created by the American Association on Intellectual and Developmental Disabilities (AAMR, 2002). Levels of support range from intermittent (just occasional or “as needed” for specific activities) to pervasive (continuous in all realms of living).
