DSM-5-TR Neurodevelopmental Disorders
Intellectual Disability: Diagnostic Criteria
Intellectual developmental disorder (intellectual disability) is a disorder with onset during the developmental period
that includes both intellectual and adaptive functioning deficits in conceptual, social, and practical domains. The
following three criteria must be met:
A. Deficits in intellectual functions, such as reasoning, problem solving, planning, abstract thinking, judgment,
academic learning, and learning from experience, confirmed by both clinical assessment and
individualized, standardized intelligence testing.
B. Deficits in adaptive functioning that result in failure to meet developmental and sociocultural standards for
personal independence and social responsibility. Without ongoing support, the adaptive deficits limit
functioning in one or more activities of daily life, such as communication, social participation, and
independent living, across multiple environments, such as home, school, work, and community.
C. Onset of intellectual and adaptive deficits during the developmental period.
Note: The term intellectual developmental disorder is used to clarify its relationship with the WHO ICD-11
classification system, which uses the term Disorders of Intellectual Development. The equivalent term intellectual
disability is placed in parentheses for continued use. The medical and research literature use both terms, while
intellectual disability is the term in common use by educational and other professions, advocacy groups, and the lay
public. In the United States, Public Law 111-256 (Rosa’s Law) changed all references to “mental retardation” in
federal laws to “intellectual disability.” Specify current severity (see Table 1): F70 Mild
F71 Moderate
F72 Severe
