"Free college" programs are widespread in American higher education. They are discussed as addressing college access, affordability, inequality, and skills shortages. Many are last-dollar tuition guarantees restricted to use at single community colleges. Using student-level data spanning the transition to college, we investigate how two similar local community college tuition guarantees in Pennsylvania affected college-going outcomes. The Morgan Success Scholarship has large impacts on community college attendance and associate degree attainment. The program diverts students away from four-year colleges, though much of this effect is temporary. Meanwhile, we find little evidence that the Community College of Philadelphia's 50th Anniversary Scholars program has any impact on college-going behavior. We suggest reasons for divergent findings and offer suggestions for practice.
