Mental rating of juvenile dependents and delinquents in Alabama

Abstract

Reports the value of group intelligence rating tests and their relation to individual examinations made by the Binet-Simon method as a part of a mental survey of four schools. Group Intelligence Rating scores of 307 white boys, 75 white girls and 264 colored boys (aged seven to 20 yrs) were stratified by the percentile achievements of 1012 white children and 765 colored children. The 20% level in colored children was found to correspond closely to the two percentile level in white children as a group score limit of feeble-minded intelligence. The largest percentage of feeble-mindedness was found among the colored boys. Compared to individual tests, the group test was found to be a labor-saving device in mental surveys of institutions.
