This is the fourth article in a series of articles from the Terminology and Classification Committee of the American Association on Intellectual and Developmental Disabilities (AAIDD). The intent of these articles is to communicate the organization's thoughts on critical issues associated with terminology, definition, and classification in the field of intellectual disability and to stimulate discussion from the field relevant to the 11th edition of AAIDD's Diagnosis, Classification, and System of Supports Manual (working title). In the first article (Schalock et al., 2007), we explained the reasons for shifting from the term mental retardation to the preferred term intellectual disability and stated that the two terms refer to the same group of people. In the second article (Wehmeyer et al., 2008), we distinguished between operational and constitutive definitions of intellectual disability and discussed their application to understanding the construct underlying the term intellectual disability. Although operational criteria for diagnosis have been generally consistent for the past 35 years, the construct underlying the term intellectual disability (and, thus, the constitutive definition of intellectual disability) has changed significantly due to the impact of the social–ecological model of disability. In this model, intellectual disability is understood as a multidimensional state of human functioning in relation to environmental demands. The third article (Thompson et al., 2009) focused on the supports and support needs of persons with intellectual disability. This article suggested that (a) supports can be conceptualized as a bridge to more meaningful life experiences and personal outcomes, (b) the support needs of individuals can be considered within models of human functioning, (c) a five-component process for individualized supports planning can guide the work of planning teams, and (d) supports planning can be differentiated from other planning approaches used in the field of intellectual disability.In this fourth article, we describe the group of individuals with intellectual disability and higher IQs and the challenges that they face in life. Individuals with an intellectual disability who have higher IQs struggle in society. This is true despite the fact that all individuals with intellectual disability typically demonstrate strengths in functioning along with relative limitations. This group of people with intellectual disability who have higher IQs constitute about 80% to 90% of all individuals with intellectual disability. (Intellectual disability is used to address the same population of individuals as the term mental retardation [Schalock et al., 2007].) Frequently, there are no identifiable causes for the disability. Most of these individuals are physically indistinguishable from the general population because no specific physical features are associated with intellectual disability at higher IQs. Similarly, unlike in the case of certain genetic “behavioral phenotypes,” no definite behavioral features are specifically associated with intellectual disability with higher IQs. Personalities also vary widely, as in the rest of the human population: Some individuals with intellectual disability are passive, placid, and dependent, whereas others are industrious, cooperative, appropriately assertive, or even aggressive and impulsive. There is considerable variation in the lifestyle outcomes achieved by adults with intellectual disability who have higher IQs. Whereas many of these individuals “living ‘independently’ predictably will need support in relation to specific issues” (e.g., housing, employment, transportation, health services; Stancliffe & Lakin, 2007, p. 443), some individuals in this group “may develop homes and home lives independent of a formal agency support once the time comes for them to live separately from their families” (Felce & Perry, 2006, p. 410). These documented outcomes contrast sharply with the incorrect stereotypes that these individuals cannot have friends, jobs, spouses, or children or be good citizens.People in this group primarily are identified when they are in school, because school demands place their intellectual and adaptive behavior limitations in clear relief and because schools have funding, bureaucracy and management systems (albeit imperfect), and a legal obligation to identify disabilities in all children. However, beyond school age, when activities may be less “intellectual,” bureaucracies do not routinely identify people having problems because of intellectual limitations (Campbell & Fedeyko, 2000), and needed services and supports are unavailable or rejected. As a result, these people continue to experience significant difficulties achieving success or even a healthy existence in adulthood.Frequently, the gap between their capabilities and the demands from their environments grows as they leave school, as society becomes more complex, and as the standards for successful adulthood climb. Well-designed individualized supports can help bridge the gap between capabilities and demands, but the reality is that many of these individuals do not have access to needed supports. Thus, life's demands frequently impose overwhelming challenges to those who live with significantly limited intellectual ability and adaptive behavior.In this article, we describe the group of individuals with intellectual disability and higher IQs and discuss how individuals in this group are delineated depending on which classification system is used. In addition, we explore how intellectual limitation exists along a continuum, revealing many similarities in human-functioning limitations between individuals on either side of the definitional dividing line. That is, individuals with intellectual disability and higher IQs (slightly below the ceiling of approximately 70–75) share much in common with individuals without a diagnosis of intellectual disability, whose functioning is sometimes referred to as borderline: Individuals who do not have intellectual disability but who have low IQs, above the ceiling of approximately 70–75. Last, we reiterate the critical importance of creating accessible, individualized supports.All people with intellectual disability, including those with higher IQs, belong to a single disability group (people with intellectual disability). However, the application of various classification systems to subdivide the group leads to somewhat different ways of understanding these individuals and their needs. Classification systems based on relevant criteria should be selected by clinicians and others for specific professional purposes that in some way benefit the individuals who are classified. For example, service providers may choose classification systems that subdivide the group of people with intellectual disability into smaller groups based on support needs, such as using the Supports Intensity Scale (Thompson et al., 2004) assessment to classify individuals by the intensity of their support needs. Physicians and geneticists may subdivide the group based on their etiology (e.g., genetic classification systems), whereas psychology and education researchers sometimes subdivide the group by or adaptive behavior (e.g., the classification of these should individuals with intellectual disability with higher IQs to into in different The of classification systems that are based on different criteria may for this group has many different of which are (e.g., p. by from definitions or classification systems (e.g., mental retardation and mental or of this group or an of this for example, the with & and the group of people with intellectual disability with higher IQs and people without intellectual disability but with IQs, whose IQs are beyond the intellectual disability Lakin, & In the have from the classification system or for classification system is is critical to that the challenges by individuals with intellectual disability who have higher IQs are and these challenges are in many ways to the challenges by the group of people with higher IQs (a) who may not be as having a disability or criteria for intellectual disability, but (b) who share many limitations in functioning with individuals with intellectual disability who have higher IQs and do these the and professional of these the is that the of these individuals are not in the are they to the mental disabilities service some may to the challenges of individuals with intellectual disability with higher IQs as to or sometimes those with intellectual disability at IQs.
