   Disparities in undergraduate STEM degree completion across different racial/ethnic groups have been a topic of increasing national concern. This study investigates the long-term outcomes of a STEM intervention program designed to increase the academic preparation, achievement and persistence of under-represented minority students.In particular, this study examines the extent to which participation in a STEM intervention program can impact the long-term persistence and graduation of first-time in college under-represented minority students. Using discrete-time competing risks analysis, results demonstrated that participants of the intervention program had a lower probability of drop out and higher probability of persisting in a STEM field of study compared to non-participants of the program. Additionally, descriptive results demonstrated that participants of the STEM intervention program had higher rates of graduation in any field compared to non-participants of the program, while program participation was not a significant predictor of six-year graduation. Findings highlight the importance of early academic preparation in Calculus and total credit accumulation to student success outcomes of URM students enrolled in STEM fields. Recommendations from this study focus on early intervention efforts, particularly in the areas of mathematics, that ensure URM students are adequately prepared with the skills needed to succeed in a STEM field of study.

   Innovative and Meaningful Mentoring to Enhance Retention, Success, and Engagement (IMMERSE) in STEM supports the retention and graduation of high-achieving, low- income students with demonstrated financial need at Skyline College, a two-year Hispanic Serving Institution situated in Silicon Valley, a hub of STEM innovation with many high-demand jobs. Over its 5-year duration, this project will fund 90 scholarships to at least 30 students who are advancing toward an associate degree or transfer to a four-year university to earn a degree in Biology, Biotechnology, Chemistry, Computer Science, Engineering, Mathematics, or Physics. IMMERSE in STEM is now in its second year and has supported 25 scholars, including 4 who have transferred to a 4-year university. All students receive up to three years of support. In addition to scholarships, the project incorporates a transformative approach to mentoring, and innovative supports intended to address financial and academic barriers. All participating students engage in a comprehensive set of evidence-based co-curricular services designed to support their persistence, completion, and transfer. Faculty mentors are trained on innovative and effective approaches to student retention and success, such as the implementation of ePortfolios. The overall goal of this project is to increase the STEM degree completion of low-income, high- achieving undergraduates with demonstrated financial need. There are three specific aims: 1) leverage existing high-impact, evidence-based processes already implemented on campus (such as ePortfolios and undergraduate research opportunities); 2) implement a cohesive multi-layer mentorship program to increase retention, student success, and graduation of scholars; 3) expand industry partnerships in association with workforce development programs to support the scholars’ academic and career opportunities with mentoring and internships. The high cost of attendance in the San Francisco Bay Area leads to high unmet financial needs, and leads students to seek part-time or full-time employment while they are in college. By combining financial assistance with specific practices, such as multi-tiered mentoring, ePortfolio adoption or participation in co-curricular activities, we have observed the impact on the retention and success rates of underrepresented minorities in STEM. This work is supported by the NSF S-STEM program under award number 2221696.

3. STEM validation among underrepresented students: Leveraging insights from a STEM diversity program to broaden participation.

   Despite significant efforts to broaden participation in postsecondary science, technology, engineering, and math (STEM) education, students from historically minoritized populations continue to face systemic barriers related to access, departmental climate, and institutional practices. Previous research suggests that campus-level STEM diversity programs often serve as a valuable resource for persistence and completion among students from underrepresented populations. However, more knowledge is needed to better understand how students experience STEM diversity programs and identify with their specific practices and activities, how those practices and activities shape students’ experiences, and how the practices, activities, and participation influence how students view themselves as members of the STEM community. Increases in the number of underrepresented students completing STEM degrees would result in new innovations to address world problems, more varied representations of scientists, and more individuals who could mentor future generations of learners. This study of 20 underrepresented students, all of whom participated in the Louis Stokes Alliance for Minority Participation (LSAMP) program, describes the programmatic influences of LSAMP that support students’ successful progress within STEM disciplines. Data reveal that: (a) students entered the LSAMP program with self-defined strengths; (b) the LSAMP program provided formal academic support; and (c) students experienced evolving forms of scientific and identity development. This study centers students’ voices to inform educational practices, policies, and future research focused on the persistent need to broaden participation in STEM careers.

   This study focuses on the increasing disparities in STEM education achievement and long-term wage earnings of under-represented minority groups. As part of national efforts to improve the diversity of the STEM workforce, this study uses longitudinal data from the University of Houston’s Education Research Center (UH-ERC) to examine the effect of participation in a STEM focused intervention program (Houston-Louis Stokes Alliance for Minority Participation) on wage earnings across students from traditionally under-represented groups. Data analysis consisted of propensity score matching analysis, followed by an ordinal logistic regression model to measure program participation effects on wage earnings. Findings indicate a significant negative association between participation in STEM intervention program and long-term wage earnings. Results highlight the role of structural racism and human capital on perpetuating achievement and wage gaps across race and socio-economic status. Recommendations focus on career-preparedness as a tool to increase the human capital of under-represented groups, and institutional shifts in policy and program components that strive to reduce the impact of structural racism on this subpopulation of students.

5. BOARD # 287: NSF S-STEM: Advancing STEM Undergraduate Success and Persistence through Scholarship, Mentorship, and Increased Sense of Belonging

   https://doi.org/10.18260/1-2--55651  

   Chang, Jen-Mei; Trajkovic, Jelena; Galvez, Gino (June 2025, ASEE Conferences)

   This paper examines the impact of a National Science Foundation Scholarships in Science, Technology, Engineering, and Mathematics (NSF S-STEM) Program at a large, Minority-Serving institution in the western U.S. Despite growing efforts to diversify STEM fields, underrepresented minority (URM) students continue to face significant challenges in persistence and success. This scholarship program addresses these challenges by providing financial support, faculty and peer mentorship, and skills development opportunities to academically talented and low-income URM STEM students. This study evaluates how participation in the program enhances key noncognitive skills, such as students' sense of belonging, leadership and collaboration skills, and science identity, which are critical to STEM persistence. Using both survey and university-based data among the 47 participating scholars, results reveal that program participants report strong levels of sense of belonging, high efficacy in leadership and collaboration skills, and strong science/math identities. Additionally, compared to university rates, scholarship students showed above-average retention and graduation rates, with the majority pursuing graduate studies or careers in STEM. These findings highlight the importance of comprehensive support programs that integrate financial aid, mentorship, and professional development to promote persistence and success among URM students in STEM fields.
