The Council for Adult and Experiential Learning (CAEL) has conducted several studies on the relationship between prior learning assessment (PLA) and adult student outcomes. Do Methods Matter? PLA, Portfolio Assessment, and the Road to Completion and Persistence presents the findings from a study that examines the relationship between PLA and student outcomes, while also exploring whether students might have different outcomes depending upon the specific method of PLA that they are using. To understand whether PLA is associated with better student outcomes, we analyzed data on degree completion and persistence+ (i.e., students who completed a degree or were still enrolled).
