PREP-aring is worth it: Success of the Case Western Reserve University Postbaccalaureate Research Education Program and its Scholars

Abstract

The Post-baccalaureate Research Education Program (PREP), established by the National Institute of General Medical Sciences (NIGMS) at the National Institutes of Health in 2000, was a research-intense, one-year training program for recent college graduates from backgrounds uncommon in science who intended to matriculate with a PhD or MD/PhD program in preparation for an eventual career in biomedical research. Case Western Reserve University had an NIGMS-supported PREP (CasePREP) from 2007 to 2025, the year NIGMS terminated the PREP funding mechanism. A major goal of CasePREP was to prepare post-baccalaureate trainees (termed Scholars) for graduate school, and major metrics of success were measured as Scholars who a) matriculated in and b) completed PhD or MD/PhD programs. A major goal of NIGMS-supported PREPs was the retention of these scientists in the biomedical research workforce. We report here the extent that CasePREP met program goals as well as the economic and scientific impact NIGMS-supported PREP has had for a variety of stakeholders. Data from 18 CasePREP cohorts included self-reported (surveys, interviews, questionnaires) and public data (websites, PubMed, NIH Reporter). Descriptive statistics and large language models were used to describe the major outcomes related to program goals and a new resilience course as well as Scholar productivity and contribution to science. Between 2007 and 2025, CasePREP was awarded $5.6 million USD and trained 108 Scholars. Most (89%) Scholars resided outside of Ohio prior to the start of CasePREP, with 38.89% from Puerto Rico. Almost all (98%) Scholars completed the one-year program in Cleveland, Ohio, and of those, 83% entered a PhD or MD/PhD program. As of September 2025, 46 Scholars have completed a PhD program, two Scholars have completed an MD/PhD program, and 27 are still in training. The attrition rate for CasePREP Scholars in graduate school is currently 14.77%, much lower than the attrition rates of national PhD programs. Most CasePREP Scholars (69.44%) are co-authors on one or more published manuscripts, and these 406 published works have garnered 14,261 total citations, with an average 35.04 citations per publication. Termination of PREP represents a five-year loss of [~]$2.7 million USD to CasePREP, a budget that would have trained an additional 30 Scholars. CasePREP was a great success as measured by its major outcomes. CasePREP Scholars have persisted in science and have made substantial contributions to the scientific workforce and enterprise. PREPs in general provided a crucial bridge for research talents who had little prior research opportunities to realize their potential and career goals. NIGMS termination of PREP support has negative economic consequences and endangers an important pathway to a career in science for Americans who would not otherwise have similar opportunities.
