The approach builds on a Phase 1 (2018-2020) planning project led by State University System of New York faculty from two- and four-year institutions (assisted by a grant from Lumina Foundation). They explored the feasibility of a nationally recognized transferable incremental credentialing system by conducting an environmental scan of nearly 90 initiatives across 41 states designed to serve students better and capture what they know. Results indicated that some states, higher education systems, and institutions were already moving toward incremental credentialing, but in different ways. Patterns of credentialing were identified and used to inform the emerging Framework of Incremental Credentialing, to be tested for usefulness at the undergraduate and graduate level in three states (Colorado, New York, and North Carolina) in Phase 2 (2021-2024) (supported by a grant from the Institute of Education Sciences, U.S. Department of Education funds). A companion effort, the Learn & Work Ecosystem Library, developed during Phase 2 in tandem with Credential As You Go. The digital, wiki model library collects, curates, and coordinates information resources to bring clarity to the evolving learn-and-work ecosystem. A Phase 3 effort (2022-2023) focused on systems change for expansion and sustainability of incremental credentials (assisted by a grant from Walmart).
