Estimates from a hazard model of college student departure for 3,975 students simulated how financial aid changes affect withdrawal decisions. Changing loans to scholarships has a large impact and front-loading aid (giving gift aid for the first 2 years) a modest impact on retention. Financial aid may represent more to students than its dollar…

Investigated the timing of dropout by college students over a 5-year period. Found that factors that affect student dropout often have effects that change over time. For instance, students who receive financial aid generally have lower dropout rates than non-aided students, but dropout rates vary depending on the amount and timing of student…

Asserting that graduation and stopout are "competing" or correlated events and that they often should be modeled as such, this study demonstrated that factors affecting timely graduation (e.g., financial aid) often have time-varying effects, and that ignoring these time-varying effects can lead to spurious conclusions that may result in…

This study describes the use of event history modeling as a tool for understanding student departure from college. Using data from the National Center for Education Statistics High School and Beyond (HS&B)/Sophomore Cohort longitudinal study a detailed history of individual students' college careers was constructed using a regression-like…
