According to the national studies (Bahr, 2009; Peter, 2006; McCormick, 2003) the proportion of college students attending multiple institutions during their undergraduate career is growing. In this report, we examined the extent of concurrent and back-and-forth enrollment, characteristics of students who attended multiple institutions, the type of colleges where they enrolled, and whether "swirling" and "double-dipping" had any impact on the retention and graduation of those students at California State University - Fresno. Data included first-time, full-time freshman cohorts from fall 2002 to fall 2007. Enrollment in other higher education institutions was tracked using the National Student Clearinghouse. The findings of the study showed that students who attend multiple institutions are more likely to need English and/or Math remediation and they have lower average GPAs at graduation. Those students are also more likely to drop-out of Fresno State, as well as to take more time to graduate. (Contains 3 tables.)
