The influence of academic, demographic, and social characteristics of college freshmen on sophomore enrollment status was investigated, along with reasons for attrition. A total of 139 freshmen at St. Edward's University in Texas were surveyed at the beginning and end of the freshman year, using the Survey of Entering Freshmen and the End of Freshman Year Survey. Significant differences were found between returners and leavers on grade point average, perceived difficulty of courses, students' satisfaction with the availability and variety of courses, expectations of finding people to date, finding their classes challenging, and expectations of the university in general based on the catalog. While students' intentions regarding enrollment at entrance did not appear to be related to their sophomore year enrollment status, intentions measured at the end of the freshman year were fairly accurate predictors. Those students who were dissatisfied with university life, and especially with social activities and with courses available, also appear to be potential leavers. In addition, students who were not continuing in required courses for the degree may be potential leavers. (SW)
