“…() utilizing a longitudinal quasi‐experimental design, provide evidence that quality mentorship (not ethnic similarity of mentor to protégé) contributed to retention and persistence of African American students drawn from 50 different institutions. Further, work by Byars‐Winston, Branchaw, Pfund, Leverett, and Newton, , which analyzed archival data from over 400 protégés collected from 2005 to 2011 from several undergraduate biology research programs, found that perceived mentor effectiveness indirectly predicted enrollment in science‐related doctoral or medical degree programs through research self‐efficacy. Mentor social support, a likely cue of kindness and belonging, may be particularly key for HU STEM students, which can impact student persistence through strengthening science identity (Hernandez et al., under review; Estrada, Zhi, & Gershon, in preparation).…”
