IntellectualDisability: Diagnostic Criteria c7 c7 c7




Intellectual developmental disorder (intellectual disability) is a disorder with onset during the developmental period that
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7




includes both intellectual and adaptive functioning deficits in conceptual, social, and practical domains. The following
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7




three criteria must be met:
c7 c7 c7 c7 c7




A. Deficits in intellectual functions, such as reasoning, problem solving, planning, abstract thinking, judgment,
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7




academic learning, and learning from experience, confirmed by both clinical assessment and individualized,
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c 7




standardized intelligence testing. c7 c7 c7




B. Deficits in adaptive functioning that result in failure to meet developmental and sociocultural standards for
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7




personal independence and social responsibility. Without ongoing support, the adaptive deficits limit
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7




functioning in one or more activities of daily life, such as communication, social participation, and
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7




independent living, across multiple environments, such as home, school, work, and community.

C. Onset of intellectual and adaptive deficits during the developmental period. c7 c7 c7 c7 c7 c7 c7 c7 c7




Note: The term intellectual developmental disorder is used to clarify its relationship with the WHO ICD-11 classification
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7




system, which uses the term Disorders of Intellectual Development. The equivalent term intellectual disability is placed
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7




in parentheses for continued use. The medical and research literature use both terms, while intellectual disability is the
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7




term in common use by educational and other professions, advocacy groups, and the lay public. In the United States, Public
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7




Law 111-256 (Rosa’s Law) changed all references to “mental retardation” in federal laws to “intellectual disability.”

This diagnosis is reserved for individuals under the age of 5 years when the clinical severity level cannot be reliably
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7




assessed during early childhood. This category is diagnosed when an individual fails to meet expected developmental
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7




milestones in several areas of intellectual functioning and applies to individuals who are unable to undergo systematic
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7




assessments of intellectual functioning, including children who are too young to participate in standardized testing. This
c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7 c7




category requires reassessment after a period of time.
