The main goal of this social policy report is to propose a holistic approach for promoting developmental success among Latinx children and youth. This report highlights the need to 1) redefine success and 2) account for intersectional inequalities. First, the current demographic landscape of Latinx students is presented to showcase the variability in experiences among Latinx children and youth. We review past policies (across the last two and current U.S. Administrations and within the state of California), educational programs (e.g., McNair scholars' program, AVID), and theoretical frameworks (within developmental and sociocultural disciplines). Next, we introduce a nuanced holistic approach for promoting Latinx children and youth's developmental success, underscoring the integration of factors within the sociocultural, family, and individual domains. Finally, this report provides accessible recommendations for policymakers, researchers, and practitioners to effectively promote equity and developmental success among diverse groups of Latinx children and youth.
