In 2021, New America released a report, "Harnessing Micro-Credentials for Teacher Growth: A National Review of Early Best Practices," exploring the benefits and challenges of leveraging micro-credentials for educators, including an informal scan of how states were integrating micro-credentials into educator policy. This publication builds on that research by providing an updated and more detailed analysis of how micro-credentials are being explicitly incorporated into state educator policies across six key areas: educator preparation, initial credential attainment, curated professional development, license renewal, acquisition of additional endorsements, and license advancement. High-quality micro-credentials offer states a tool to address teacher shortages by attracting and retaining a skilled and diverse educator workforce capable of helping students meet their full potential. This report discusses best practices in educator micro-credential policy design and implementation and recommends six actions for state education leaders to harness this promising tool.
