Quizplus · Accepted Answer

In order to classify someone as mentally retarded, they must have an IQ score of approximately 70 or below, in addition to deficits in adaptive functioning (such as difficulties in performing daily tasks). Chromosomal abnormalities, manifestations of violent behavior and withdrawal, and proof of not having phenylketonuria are not necessary criteria for a diagnosis of mental retardation.
