Intellectual Disability: Diagnostic Criteria we we we
Intellectual developmental disorder (intellectual disability) is a disorder with onset during the developmental period that in
we we we we we we we we we we we we we we we
cludes both intellectual and adaptive functioning deficits in conceptual, social, and practical domains. The following thre
we we we we we we we we we we we we we we we
e criteria must be met:
we we we we
A. Deficits in intellectual functions, such as reasoning, problem solving, planning, abstract thinking, judgment, acad we we we we we we we we we we we we we
emic learning, and learning from experience, confirmed by both clinical assessment and individualized, standa
we we we we we we we we we we we w e we
rdized intelligence testing. we we
B. Deficits in adaptive functioning that result in failure to meet developmental and sociocultural standards for perso we we we we we we we we we we we we we we we
nal independence and social responsibility. Without ongoing support, the adaptive deficits limit functioning in
we we we we we we we we we we we we we we
one or more activities of daily life, such as communication, social participation, and independent living, across
we we we we we we we we we we we we we we we we
multiple environments, such as home, school, work, and community. we we we we we we we we
C. Onset of intellectual and adaptive deficits during the developmental period. we we we we we we we we we
Note: The term intellectual developmental disorder is used to clarify its relationship with the WHO ICD-
we we we we we we we we we we we we we we we
11 classification system, which uses the term Disorders of Intellectual Development. The equivalent term intellectual disa
we we we we we we we we we we we we we we we
bility is placed in parentheses for continued use. The medical and research literature use both terms, while intellectual disa
we we we we we we we we we we we we we we we we we we
bility is the term in common use by educational and other professions, advocacy groups, and the lay public. In the United Sta
