Intellectual disability is currently defined by the American Association on Intellectual and Developmental Disabilities as “a disability characterized by significant limitations both in intellectual functioning and in adaptive behavior as expressed in conceptual, social, and practical adaptive skills. This disability originates before age 18.” Diagnosis requires standardized measurement of both intelligence and adaptive function and should be periodically re-evaluated with repeat psychological, educational, and achievement assessment.
