This phenomenological study examined the reports of Foster Care Alumni (FCA) regarding their resilience while obtaining a postsecondary degree. According to recent estimates, there are 391,098 children in the U.S. foster care system (AFCARS, 2022, 2019; Child Trends, 2015). Foster youth are among America's most disadvantaged in terms of postsecondary education opportunities (Dworsky, 2018). Of the 10% of foster youth who enroll in college, 3% obtain a college degree (Pecora et al., 2006; Wolanin, 2005). This national study centered on the lived experiences of FCA who obtained a postsecondary degree and identified the strengths and assets that helped them thrive in postsecondary education environments. The research draws attention to postsecondary institutions that historically have not been prepared or self-critical to support students from excluded populations such as FCA. The data revealed what FCA reported regarding their personal, social, familial resiliency, and institutional safety nets while thriving in their postsecondary institutions. Addressing the educational achievement gap of FCA is a social justice issue and a national crisis. Postsecondary institutions play an important role and partnership in ameliorating barriers for FCA. Interpretative Phenomenological Analysis (IPA) and semi-structured interviews were employed to examine what FCA reported regarding how they perceive their resilience. The findings identified four major themes: (1) supportive familial relationships, (2) dispositional traits, (3) demonstrated qualities and assets, (4) institutional deficits and norms of White privilege. The themes were rooted in FCA knowledge holders' experiences and narratives, which allowed for an extensive description of the factors related to how FCA perceived their resilience. The findings offer national insights for postsecondary institution practitioners and leaders to best support FCA from a strength-based perspective. This research contributes to a national understanding of the limited body of asset-based literature on FCA and postsecondary education opportunities. The conclusions add to our understanding of the strengths and assets that allow FCA to thrive and achieve their postsecondary aspirations.
