In this report we walk through a systematic review of how PLA [prior learning assessment] was implemented under the ideal circumstances provided by the TAACCCT [Trade Adjustment Assistance Community College and Career Training] grant program. We found that there was positive policy development, but student use of PLA opportunities remained low. In some isolated places, we found policy and practice changes that were connected to an increase in students' use of PLA. From this analysis, we distilled lessons on implementation and suggest how to scale up the use of PLA in higher education.
