Abstract
This study examines how artificial intelligence (AI) is reshaping educational policies in the United States, with a focus on California, Texas, Florida, and New York. Drawing on policy diffusion theory and institutional isomorphism, this study examines state-level policy approaches to AI integration, equity, and ethics in K–12 education within the broader federal policy context. Data were drawn from policy briefs, executive orders, task force reports, guidance documents, and policy updates issued between January 2023 and January 2026. Using structured juxtaposition, the analysis examines cross-state variation in policy approaches and the extent to which federal guidance, equity, and ethical concerns are reflected in state-level responses. Findings reveal emerging patterns of convergence and divergence between federal guidance and state legislation shaped by political support, institutional capacity, and policy priorities. This study contributes to the literature by identifying emerging patterns of AI governance across states, clarifying the role of federal guidance as a normative reference point, and advancing understanding of how equity and ethical considerations are embedded in state AI education policies. This study also highlights implications for educational policy, practice, and future research to ensure AI in K-12 education is adopted in ethical and equitable ways within a decentralized federal system.
