Burdened by a significantly below average functioning of overall intelligence, coupled with deficits in adaptive behaviour, a child affected by intellectual disability manifests severe delays in achieving developmental milestones in cognition, communication, and academics. A special teaching environment can help the child reach several of these milestones in due course, making the child independent in activities of daily living, grooming, hygiene and eating. Such children can also achieve academic milestones at their own pace depending on the severity of their disability.
