Per the overview: "As a relatively new trend in professional development, the advantages and challenges of implementing micro-credentials are not fully understood. We undertook this research as a way to address a need for a synthesis of learnings from early micro-credential endeavors. As part of our Performance Assessment for Learning Micro-credential project, we met many others interested in developing or sharing effective strategies for using micro-credentials, and used that as a launching point for investigating them more deeply. As the field increases the development of micro-credentials, it is useful to understand what others have learned. We hope our insights will contribute to developing sustainable, effective professional development via micro-credentials. In this paper we highlight the unique features of six micro-credential initiatives, including points of divergence and commonality across the various approaches and their impact on implementing educator micro-credentials."
