Initiated in October 1966 by the Department of Defense, Project One Hundred Thousand accepts men who would not have qualified for military service under previous standards, and upgrades them medically and educationally. Major aims are to broaden opportunities for enlistment, equalize military service obligations, assure foresighted military planning, and, through Project Transition, help "new standards" men become productive citizens when they return to civilian life. Minimum performance standards will not be reduced; instead, if necessary, extra time and effort are extended. Project results are monitored in detail. Up to April 1968, 96,639 men had been accepted, most under the new mental standards. Results in terms of graduation rates, conduct and efficiency, promotions, and assignment to occupational specialties having potential civilian utility have been favorable. Seminars and research have also been sponsored to enhance program success and promote information exchange among military services. (Statistical data on recruitment, participant characteristics, performance, behavior, supervisory ratings, job assignments, and attrition from active service are included.) (ly)
