The fact that delinquent boys tend to read at levels below their mental age is fairly well established in the literature (3). The suggestion is strong that delinquency and reading retardation may share a mutual etiology and causal relationship. Even stronger is the suggestion that the possibility of the rehabilitation of the delinquent youth on probation may be greatly enhanced if he is treated for reading retardation (5).
