Who are mentally retarded children?

The mentally retarded children fall into the lower end of the scale of intellect and academic aptitude in the categorization of exceptional children, which is completely opposite and counter to the brilliant and creative who fall into the high end of this scale. In terms of vocabulary, such youngsters are also referred to as "feeble-minded," "mentally handicapped," "mentally defective," "mentally subnormal," or "mentally sub-average," among other terms. Whatever label we give them, it denotes a group of kids with below-average mental functioning, which has an impact on not only their behaviour and future development but also poses major challenges for those who are in charge of their care.
