This is a comparative study presenting data for 12 campuses of the City University of New York. The primary focus is upon the first freshman class under the Open Admissions Program that began in September 1970. Outcomes for this class are considered over a period of three semesters. The 1970 and 1971 freshmen are also compared with regard to their performance in the first term of their freshman year. The background of Open Admissions is described, and the major features of the program are discussed, with social and economic characteristics of the students also considered. Students are compared (within colleges and across colleges) on two major criteria of academic success: grade-point averages and rates of credit generation. A similar set of analyses are carried out with regard to the effects of remedial and compensatory education programs. Dropouts and nondropouts are compared with regard to the characteristics of their academic performance. Attrition data for the University are compared with national findings. The 1970 and 1971 freshmen classes are compared with regard to indices of academic success and the effects of remedial programs. (Author/MJM)
