Undergraduate education in the US is racially/ethnically stratified, and there is limited mobility for Black and Latinx BS recipients in STEM majors into the PhD programs from which faculty hiring disproportionately occurs. Bridge programs are proliferating as a means of increasing minoritized students’ enrollment in STEM graduate programs, but little social science examines mechanisms of their impact or how impacts depend on the graduate programs to which students seek access. This sequential mixed methods study of the Cal-Bridge program analyzed trust networks and mechanisms of relational trust as factors in graduate school application, admissions, and enrollment decisions. First, using social network analysis, we examined patterns in the graduate programs to which seven cohorts of Cal-Bridge scholars applied, were admitted, and chose to enroll. Then, we conducted an in-depth case study of the organization in the Cal-Bridge network with the highest centrality: University of California, Irvine’s physics and astronomy PhD program. We find the positive admission and enrollment outcomes at UC Irvine were due to intentional, institutional change at multiple organizational levels. Change efforts complemented the activities of the Cal-Bridge program, creating conditions that cultivated lived experiences of mutual, relational trust between bridge scholars and their faculty advisors and mentors. Findings illustrate mechanisms and antecedents of trust in the transition to graduate education. We use these findings to propose a framework that may inform the design of future research and practical efforts to account for the role of trust in inequities and creating more equitable cultures in STEM.

Time to PhD completion is no different between men and women despite score gap on physics GRE
Using analysis of variance on a sample consisting of 1,499 US students across 21 US PhD programs, we show that there is no significant difference in the time it takes US male and female physics PhD students to complete their degree programs. This result comes in spite of a statistically significant 18 percentile point gap in median GRE-P scores between genders. Additional analyses reveal that there is no statistical difference between US students reported as White, Black/Hispanic/Multiracial/Native American, and Asian. Expanding our sample to also include 1,143 Non-US students, we find a small but significant effect of citizenship status on time to PhD completion where the average time for Non-US students to complete a physics PhD is about two months less than their US student counterparts. These results show that in spite of known gaps in standardized admissions exams between genders, these differences are not reflected in subsequent graduate school performance. Our findings reinforce the need for graduate admissions committees to go beyond quantitative metrics and conduct a holistic assessment of an applicant's potential to perform research effectively and to earn a PhD.

Many undergraduate neuroscience trainees aspire to earn a PhD. In recent years the number, demographics, and previous experiences of PhD applicants in neuroscience has changed. This has necessitated both a reconsideration of admissions processes to ensure equity for an increasingly diverse applicant pool as well as renewed efforts to expand access to the training and research experiences required for admission to graduate programs. Here, we describe both facets of graduate school admissions by demystifying the process and providing faculty with tools and resources to help undergraduate students successfully navigate it. We discuss admissions requirements and processes at two graduate institutions, highlighting holistic approaches to evaluating students, the ever-increasing research experience expectations, and the decreasing reliance on the GRE. With a particular focus on improving equity, diversity, inclusion and belonging, we discuss resources for applying to graduate school that are available for students from underrepresented populations, including summer institutes and fellowship programs and intentional relationships with minority serving institutions (MSIs) to foster bi-directional engagement between undergraduate programs at MSIs and graduate institutions. With diverse perspectives as faculty involved in undergraduate education, graduate programs, and post-baccalaureate training programs, we provide recommendations and resources for how to help all trainees — especially those from populations underrepresented in the STEM workforce — succeed in the current graduate education admissions landscape.more » « less

Physics departments are increasingly working to improve diversity in graduate programs by using more holistic strategies in their admission and retention practices. However, completion rates for traditionally underserved groups are still problematic. By understanding and accounting for faculty and student divergence on challenges faced in retention, graduate programs will be better equipped to enact change. In this study of two graduate programs (one physics and the other astrophysics), faculty and graduate students were asked why graduate students leave their program, and to identify ways to reduce attrition. While the goal of improving retention was shared between faculty and graduate students, their visions for how retention could be improved were not aligned. Faculty believed that retention could be improved by reforming admissions practices to select for students with attributes critical for success in graduate school, such as resilience. In contrast, the graduate students noted more systemic or socio-cultural factors as impacting retention.more » « less

This study aims to understand the effectiveness of typical admissions criteria in identifying students who will complete the Physics Ph.D. Multivariate statistical analysis of roughly one in eight physics Ph.D. students from 2000 to 2010 indicates that the traditional admissions metrics of undergraduate grade point average (GPA) and the Graduate Record Examination (GRE) Quantitative, Verbal, and Physics Subject Tests do not predict completion as effectively admissions committees presume. Significant associations with completion were found for undergraduate GPA in all models and for GRE Quantitative in two of four studied models; GRE Physics and GRE Verbal were not significant in any model. It is notable that completion changed by less than 10% for U.S. physics major test takers scoring in the 10th versus 90th percentile on the Quantitative test. Aside from these limitations in predicting Ph.D. completion overall, overreliance on GRE scores in admissions processes also selects against underrepresented groups.more » « less

The use of the Physics GRE in graduate admissions has gained considerable attention in recent years. While studies have shown the problematic nature of the exam quantitatively, it is time that student experiences were also included in the discussion. In this qualitative study, we interviewed 69 current graduate physics and astronomy students about their process of deciding where to apply to graduate school. Physics GRE requirements played a substantial role in this decision, with 48 students mentioning the test as part of their process to narrow programs down to a personalized short-list. Participants discussed potential barriers (e.g., financial and travel) that affected some students, but not others, which created an unequal playing field for grad school applicants. Secondly, while the participants noticed a shift towards more departments having "optional'' GRE language, female student participants still felt the need to take and submit their Physics GRE scores, while male student participants truly saw "optional'' as optional. These results suggest that graduate programs requiring the Physics GRE are doing more than asking prospective graduate students to simply take a physics test, and that the use of 'optional' requirement language may be inadvertently disadvantaging the very students that they are trying to recruit.more » « less
