Mentally Defective Children

The authors present a practical framework for identifying and educating children with delayed or abnormal intellectual development, combining psychological testing, medical examination, and classroom observation. They explain the Binet-Simon intelligence tests as screening tools to flag pupils who may require specialized instruction, distinguish two main categories of impairment, and argue that physical signs alone are insufficient for diagnosis. The book outlines procedures for teachers, inspectors, and doctors, proposes curricula emphasizing practical workshop training over abstract instruction, and stresses that special schools should aim to make pupils socially useful and employable according to their capacities.
