“…In sum, prior research employing a host of empirical strategies to isolate the causal effect of PBF on unintended consequences has shown that PBF policies were associated with restricting access to certain types of students who may have been deemed less likely than their peers to graduate, such as low-income students and underrepresented minority students (Birdsall, 2018; Umbricht et al, 2017). Additional literature typically using a similar quasi-experimental approach also suggests that PBF policies lead to gaming of the PBF system by focusing on short-term certificate production (Hillman et al, 2018; Hillman et al, 2015; Li & Ortagus, 2019) and a funding structure in which disadvantaged student groups and institution types face further disadvantages following PBF adoption (Hagood, 2019). In response to the equity concerns described above, several PBF-adopting states have amended their PBF policies to include equity bonuses or premiums, but the limited body of evidence pertaining to the efficacy of equity premiums reveals conflicting, but at least somewhat promising, results regarding their impact on Black, Hispanic, and low-income student enrollment (Gándara & Rutherford, 2018).…”
