The graduation rates of students admitted to the City University of New York (CUNY) by open admissions was studied as an extension of previous research. A sample of the initial freshman classes of 1970 and 1971 were tracked over a period of 11 years. A total of 4,705 open admissions students were compared to 8,084 regularly-admitted students. Since CUNY's policy was designed to expand educational opportunity for disadvantaged minority groups, data were also assessed for four major ethnic constituencies that comprise the majority of CUNY's entering classes. Graduation data were compared for White ethnic groups (Jewish and White Catholic) and minority groups (Black and Hispanic). Data are presented separately for CUNY's four- and two-year colleges. It was found that in the senior colleges, 34 percent of regularly-admitted students graduated after 4 years, and 62 percent needed 5 years or longer. Among open admissions students, only 16 percent earned diplomas after 4 years, but after 11 years 43 percent graduated. In the two-year community colleges, 45 percent of regular students and 28 percent of open admissions students completed their community college studies after 11 years. Additional time to graduate appeared especially important for CUNY's minority students. (SW)
