Despite uncertainty related to student outcomes resulting from remediation (Bettinger & Long, 2009), eleven states mandate remedial education through common placement testing and standardized cutoff scores rather than permitting individual postsecondary institutions to establish remediation guidelines. Colorado, in particular, offers an exemplary look at how such policies have manifested on the state level. This policy analysis used a fixed effects model on panel data in order to determine the impact of statewide mandatory remediation policies on college graduation and persistence rates for states as a whole as well as at the two-year and four-year institutional levels. Examining the larger national context revealed statewide mandatory remediation policies offered no significant impact on state-level college degree completion or retention rates. A closer look at the state of Colorado showed similar null effects on community college graduation rates. However, institutional retention rates were significantly improved at all levels of higher education as a result of Colorado's statewide mandatory remediation policy.
