Addressing Latinx student underrepresentation in STEM requires an assets-based reimagining of STEM experiences and pathways that facilitate student success. Drawing on data from two qualitative studies of Latinx students pursuing STEM majors, findings reveal that Latinx students draw on at least six distinct forms of cultural assets to facilitate their, and at times their peers', persistence in STEM. Latinx students then utilize these cultural assets to develop culturally grounded understandings of themselves as STEM individuals.
