TWO APPROACHES WERE USED IN STUDYING THE EFFECTS OF THE NEIGHBORHOOD YOUTH CORPS (NYC) ON MILWAUKEE, WISCONSIN -- (1) IMPLICATIONS FOR THE INTERNAL AND EXTERNAL OPERATIONS OF ORGANIZATIONS INVOLVED IN ITS WORK FLOW, AND (2) IMPLICATIONS FOR SPECIFIC PROBLEMS IN THE YOUTH AND POVERTY AREAS (SCHOOL ATTENDANCE AND ACHIEVEMENT, JUVENILE DELINQUENCY, YOUTH UNEMPLOYMENT, DEPENDENCY, AND OTHERS). DATA WERE COLLECTED PRIMARILY THROUGH PERSONAL INTERVIEWS IN 41 AGENCIES INVOLVED IN THE NYC WORK FLOW, REPRESENTATIVES OF OTHER AGENCIES DEALING WITH POVERTY AND YOUTH PROBLEMS, AND CRITICS OF ESTABLISHED AGENCY SERVICES. THE TWO NYC PROGRAMS IN MILWAUKEE ARE -- (1) A PROGRAM FOR IN-SCHOOL YOUTH SPONSORED BY THE MILWAUKEE SCHOOL BOARD IN OPERATION SINCE SPRING 1965, AND (2) A PROGRAM FOR OUT-OF-SCHOOL YOUTH SPONSORED BY THE MILWAUKEE COUNTY GOVERNMENT, OPERATING SINCE JANUARY 1966. AMONG THE COMMON FINDINGS ARE -- (1) POLITICAL INTERFERENCE WITH AGENCY INTERNAL OPERATIONS HAS BEEN NEGLIGIBLE, (2) THE PRESENCE OF ENROLLEES IN AN AGENCY TENDS TO INCREASE THAT AGENCY'S EFFECTIVENESS IN COMPLETING ITS TASKS, (3) SCHOOL OFFICIALS BELIEVE NYC IS USEFUL IN IMPROVING ATTENDANCE, PERFORMANCE, AND BEHAVIOR OF MILDLY PROBLEMATIC YOUTH, AND (4) NYC BOTH CONTRIBUTES TO AND SUFFERS FROM THE RELATIVE DISORGANIZATION OF COMMUNITY SERVICES.
