Objective: This study develops an analytical framework for identifying effective partnerships between 2- and 4-year institutions that enable community college entrants to transfer to a 4-year institution and earn a bachelor's degree in a timely fashion. Method: Using the individual term-by-term college enrollment and degree records from the National Student Clearinghouse for the entire 2007 fall cohort of first-time-in-college community college students nationwide, we use regressions to control for student and institutional characteristics in identifying effective partnerships in two steps: first, we identify community colleges with large residual values (better than expected outcomes); and second, we identify the 4-year partners of those community colleges with large residual values. Results: Descriptive results on the variation in transfer outcomes among the thousands of unique transfer partnerships nationally are presented alongside results from regressions used in the two-step effective transfer partnership identification. Contributions: Recommendations and considerations for using this framework to evaluate and benchmark institutional performance in supporting the academic success of vertical transfer students for baccalaureate attainment are also discussed.
