California State University, Bakersfield (CSUB) successfully completed a six-year initiative (including a no-cost extension in its final year) funded by the U.S. Department of Education's Promoting Post-Baccalaureate Opportunities for Hispanic Americans (PPOHA) program (Award No. P031M190029; $2.99 million). The project aimed to expand graduate capacity in STEM fields and strengthen academic pathways for Hispanic and low-income students. Key Achievements: (1) Enrollment Growth: Hispanic graduate full-time equivalent (FTE) enrollment rose from 52% to 60.8% between 2019 and 2024; (2) Program Expansion: Over 60 workshops, 93 virtual graduate fairs, and 270 Grad Slam presentations were conducted; (3) Research Infrastructure: More than 30 faculty-student research teams were formed, supported by robust mentoring resources and campus-wide tracking systems; and (4) Institutional Integration: The project fostered cross-departmental networks, established strategic partnerships with UC Merced and Keck Graduate Institute, and launched a Doctor of Nursing Practice (DNP) pathway. The evaluation employed a progressive theoretical framework (CIPP [right arrow] RBA [right arrow] PPCT [right arrow] Triple A) to assess outcomes systematically. Despite COVID-19 disruptions, strategic pivots to virtual delivery accelerated participation. Year 6 served as both capstone and catalyst, culminating in a Graduate Excellence Celebration Symposium. This report provides evidence-based recommendations for sustaining gains and informing future PPOHA initiatives across Hispanic-Serving Institutions.
