This study examined the impact of a National Science Foundation-funded support program for academically promising STEM students from low-income backgrounds. The program operates as a collaborative consortium, bringing together three public community colleges and one private university, to support the retention and graduation of program scholars. Using propensity score matching, we compared 169 program scholars to 169 matched non-scholars with similar demographic, academic, and financial characteristics (Mage= 24.82 years; 41% female; 60% students of color). Participation in the program was associated with favorable academic outcomes, with large to moderate effect sizes. Specifically, program scholars had significantly higher cumulative and STEM-specific grade point averages than their non-scholar counterparts. They also completed significantly more STEM courses and were less likely to withdraw from college than non-scholars. These findings underscore the potential of comprehensive and equity-oriented approaches to STEM education in facilitating academic success for STEM students, particularly those from low-income backgrounds.
