The success of Latino college students is dually critical to the social well-being of the Latino community and the sustainability of the national economy. To garner the intellectual and economic potential of this population, it is critical to address their retention and completion rates, particularly within science, technology, engineering, and math (STEM). Growth mindset, the belief that intelligence is fluid and can be developed with effort, is one promising attribute with the potential to affect degree completion and success of Latina/os by addressing learning mindsets that influence academic performance. Emerging evidence demonstrates the positive impact of growth mindset frameworks on GPA, retention, and persistence. While growth mindset is applicable to all student populations, it uniquely addresses the academic underachievement of minority students. This qualitative case study explored the impact of growth mindset interventions on first-generation and low-income Latino students within a summer STEM academy. Social cognitive theory contributed the critical lens for examining the intersectional impact of personal characteristics and institutional supports on student academic behaviors. Focus group interviews were conducted with a subset of summer bridge students (n = 10) at a small, private Hispanic-serving university in the southwestern U.S. This study yielded four main findings: (a) growth mindset interventions influence the academic performance of vulnerable populations; (b) additional learning mindsets, namely, belonging, self-efficacy, and relevance, affect academic achievement; (c) mindsets are malleable and can be developed with short-term intervention; and (d) career ambitions were salient to student goals. This research concludes that STEM summer bridge programs should integrate a diverse learning mindset framework--including growth mindset, belonging, relevance, and self-efficacy--into the curricula to strengthen the effectiveness of programmatic efforts.
