intellectual disability

noun

: mild to severe impairment in intellectual ability equivalent to an IQ of 70 to 75 or below that is accompanied by significant limitations in social, practical, and conceptual skills (as in interpersonal communication, reasoning, or self-care) necessary for independent daily functioning and that has an onset before age 18

Note: The term intellectual disability is now preferred over mental retardation in medical, educational, and regulatory contexts, as well as in general use. The term mental retardation is increasingly considered offensive, though it was the dominant term into the second decade of the current century.
