The completion agenda demands higher community college graduation rates among adult learners, and prior learning assessment (PLA) is a promising solution. PLA permits students to earn credit for college-level learning acquired outside of higher education and is associated with improved student outcomes. However, little is known regarding community college graduation rates among adult learners by prior learning assessment status and method. Therefore, the purpose of the current study was to examine adult learner graduation rates by PLA status and method at four U.S. community colleges. Results from this foundational study confirmed a remarkable difference in graduation rates between adult PLA learners and adult non-PLA learners, uncovered striking differences in the graduation rates of adult PLA learners by PLA method, and identified a relationship between PLA method and graduation. Findings provide community college stakeholders with new insight into adult PLA learners in the community college and a basis for future research leading to higher graduation rates among adult learners.
