With the implementation of an open admissions policy in 1970-71, Bronx Community College undertook a study of students entering in the fall of 1970 to determine changes in levels of academic preparation, trends in attrition and retention for students differentially prepared for college work, identification of entry variables associated with dropping out or continuing successfully, and the rate and pattern of progress for different groups of students. At the beginning of the spring semester of 1970-71, freshmen who did not return were compared with those who returned on a number of variables, including high school average, high school curriculum, reading score, type of high school attended, and admissions classification (would have been rejected in 1969 for inadequate high school average, would have been rejected for subject-matter insufficiencies, or would have met 1969 requirements). The most important finding is the apparent absence of clear or strong relationships between the entry variables and the tendency to drop out after one semester. This is indicated despite the relationships linking high school mathematics (amount and proficiency) and the type of high school to the dropout rate. The open-admissions student does not show a significantly higher dropout rate than the "fully qualified" student. A replication of this study covering an entire academic year is recommended, as well as studies of the influence of non-scholastic factors on the tendency to drop out. (KM)
