California State University, Bakersfield (CSUB) continues administering its five-year grant, "Promoting Excellence in Graduate Education and Increasing Hispanic STEM Related Degree Completion," that began in the Fall of 2019 to strengthen the STEM program support for students of Latino origin and develop a Graduate School-Going culture across the campus. In the fourth year, the grant team launched extensive STEM education undertakings, including organizing 11 Graduate Student Center workshops and Grad Slam events, sponsoring eight faculty scholarship presentations, supporting research projects for nine faculty fellows, admitting nine students in a Graduate Collaborative Research Program, funding ten students in a Graduate Mentor Supplement Program, purchasing lab supplies, and monitoring student rate of progress toward program completion. This report incorporates both quantitative and qualitative data to assess service effectiveness and address project demands against unique challenges. Built on a review of past recommendations and a summary of the fourth-year findings, the evaluator adduced three new recommendations to sustain the project improvement next year.
