While abundant studies on college student departure exist, few studies focus on student transfer-out behaviors. One may reasonably believe that transfer students leave their institutions at different times for different reasons. Coupled with the national dataset, this study longitudinally investigated transfer students who left their initial 4-year institutions. Results suggest that student characteristics, such as race and family income, had varying effects on the timing of transfer. Social integration was found to have significant effects on reducing the likelihood of transfer.
