The brief critical examination focuses on existing special education practices in schools in which diagnosis is said to have become a suspicion confirming exercise. Labeling-categorization of children with either mild or severe degrees of exceptionality is singled out as a harmful practice. Ethical and legal issues then considered are the variance…
