College presidents are receiving heightened public attention and scrutiny, but few data exist that demonstrate which college presidents are most effective at improving student outcomes. This report ranks over 400 current and former college and university presidents on how much they improved access, affordability, and student success during their tenure as president. The rankings reveal that some college presidents are superstars. While president, these individuals cut tuition costs, increased the share of students from low-income and underrepresented racial backgrounds, and increased graduation rates. Other presidents, however, did little to improve these outcomes, and some presidents oversaw steep declines in these outcomes. The author argues that higher education boards, students, and policymakers should pay more attention to how presidents improve student outcomes. Rankings such as these could provide some much-needed pressure on college presidents to elevate their performance on improving access, affordability, and student success.
