It then examines different strategies for implementing micro-credentials and some of the structural options institutions face. Finally, it looks at potential issues regarding costs, quality assurance, and a lack of data around micro-credentials that could cause problems if not addressed properly. The overall message is that micro-credentials are promising but institutions need to carefully consider challenges around execution and quality.
