Postsecondary education and training have become essential to economic mobility, and equitable access to postsecondary education and training is critical to building an inclusive economy. Part of building inclusivity is increasing the number of and diversity of working people earning these quality credentials in workforce education and training programs. Good data and information on non-degree credentials are key to ensuring that public investments help working people, students, local businesses, and policymakers meet their workforce goals. However, most states do not have the robust data ecosystem they need to fully maximize the benefits of high-quality non-degree credentials and protect against those that are low-quality. This publication charts a course that state policymakers--specifically governors, state agency leaders, and legislators--and advocates can use to achieve a robust non-degree credential data ecosystem. It provides state policymakers with: (1) A description of a robust non-degree credential data ecosystem and its elements; (2) Specific actions that state policymakers can take to develop the elements of a robust data ecosystem with real-world state examples; and (3) Considerations to inform their journey toward a robust data ecosystem. For state agency leaders and staff who are engaged in the essential technical work of developing a data ecosystem, the appendices in this publication include an assessment tool that states can use to determine which elements of a data ecosystem they have and which ones they still need, and a list of additional resources that may be useful for the technical aspects of developing a robust data ecosystem.
