The academic fate of students from different ethnic groups under open admissions at City University of New York is examined. Three central questions are addressed: (1) Who came and how was the ethnic composition of the university affected by open admissions? (2) To what degree did different parts of the university become ethnically integrated? (3) How did the members of different ethnic groups do? The analyses cover the first five years of open admissions and utilize four types of data. Open admissions did provide important access to the university for minority students, but more whites than minority students benefited from the policy for the years 1970-72. The distribution of minority groups at the university became more equal as a result of open admissions, but some stratification did remain. The impact of stratification at preceding levels of the system, in high schools and elementary schools, continued to be felt. Minority students were more likely to be found in the technical-vocational curricula, but student preferences appear to be the contributing factor. Students in the open admissions program did well by comparison with national norms. Even when high school performance was controlled, relatively consistent and sometimes large differences were visible in ethnic rates of success. In the senior colleges, Jewish students were generally the most successful and Hispanic students were the least successful. In the community colleges, the white groups were generally more successful than the blacks and Hispanics. Ten statistical tables are included. (SW)
