The problem of the youthful mentally retarded offender was studied and a plan devised to meet it. Recommendations called for special units for retarded offenders, placement as retardates rather than delinquents, periodic evaluation of the individual's rehabilitation program, and coordination of followup services. Further recommendations concerned development of a state system of detention-evaluation centers and of programs to identify and evaluate handicaps in offenders and to utilize local resources in care and treatment. A statewide system of juvenile courts was also proposed along with the following preventive measures: inschool testing and special placement, inservice training for professionals, interagency coordination, juvenile police divisions or officers, and agency-police cooperation.
