Major purposes of the urban cooperative work education programs study were to assess the effectiveness of secondary and postsecondary cooperative education programs in the nation's hundred largest cities and to analyze the postprogram experiences of both participants and nonparticipants. Thirty case studies were compiled from 19 secondary and 11 postsecondary cooperative education programs located in cities. Interviews were conducted with 675 students participating in the 30 programs and with a cohort group of 774 vocational students not enrolled in the programs to compare their school and job experiences and satisfaction. More participants than nonparticipants had positive attitudes and were employed, with the postsecondary participants scoring higher in the satisfaction areas. In addition, a followup study of participants and nonparticipants in the 50 primarily nonurban programs studied in part I of the assessment study indicated that where comparable data were available the outcomes were approximately the same. Study conclusions were that the program populations of minority, disadvantaged, and average to below-average students were generally competent and well-motivated and had high job placement rates, except in cities with high unemployment. Major constraints to expansion of the cooperative programs were lack of a sufficient number of coordinators and adverse economic conditions.
