THE PRIMARY CRITERIA FOR JUDGING NEIGHBORHOOD YOUTH CORPS (NYC) PROGRAM EFFECTIVENESS IN CINCINNATI, OHIO, DURHAM, NORTH CAROLINA, EAST ST. LOUIS, ILLINOIS, AND ST. LOUIS, MISSOURI, WERE COMMUNITY AND WORK ADJUSTMENTS. AN EXPERIMENTAL GROUP COMPOSED OF 392 ENROLLEES WHOSE NYC EXPERIENCE WAS A LITTLE MORE THAN A YEAR AND A CONTROL GROUP COMPOSED OF 205 SIMILAR YOUTHS WHO HAD NOT ENROLLED IN NYC WERE INTERVIEWED TO OBTAIN INFORMATION ON NYC RECRUITMENT, WORK ASSIGNMENTS AND THEIR VALUE, LENGTH OF EXPERIENCE, SUPERVISION, FRIENDLINESS OF FELLOW-WORKERS, COUNSELORS, USEFUL AND DISLIKED ASPECTS OF EXPERIENCE, AND JOB PLACEMENT. THE MOST SIGNIFICANT FINDINGS WERE--(1) THE PROGRAM IS REACHING SERIOUSLY DISADVANTAGED YOUTH, (2) ENROLLEES REPORTED A HIGH LEVEL OF SATISFACTION WITH THEIR NYC EXPERIENCE, (3) THE COMMUNITY AND WORK ADJUSTMENT OF ENROLLEES WAS IMPROVED ON SEVERAL MEASURES, AND (4) FEMALE ENROLLEES MADE GREATER GAINS THAN MALES. SOME PROBLEM AREAS CONCERNED THE PROGRAMS' LESSER EFFECTIVENESS WITH MALES AND WHITE FEMALES THAN WITH NEGRO FEMALES AND THE CONTINUING HIGH UNEMPLOYMENT RATE OF EX-ENROLLEES WHICH WAS PROBABLY RELATED TO THE CHARACTER OF NYC WORK ASSIGNMENTS. ISSUES NEEDING FURTHER EXPLORATION INCLUDED JOB DEVELOPMENT, RELATIONSHIPS WITH OTHER MANPOWER PROGRAMS, REMEDIAL EDUCATION, FOLLOWUP COUNSELING, AND DIFFERENTIAL ENROLLEE NEEDS. THE EXTENSIVE APPENDIXES INCLUDE TECHNICAL INFORMATION, THE INTERVIEW SCHEDULE, OCCUPATIONAL CATEGORIES, AND SPECIFIC INFORMATION FROM THE CINCINNATI AND DURHAM NYC'S. (MM)
