Adult learners are a growing population in U.S. postsecondary education who experience distinct barriers to academic success. However, higher education institutions continue to create and adhere to policies that favor traditional college students. Thus, adult learner experiences must be better understood to ensure this population is supported. This study used data from the 2013 and 2014 administrations of the National Survey of Student Engagement to identify characteristics of adult learners and compare their engagement with traditional-aged students. Our regression analysis revealed that adult learners were more likely to take their classes online, begin their education at another institution, and enroll part-time. Adult learners also were more engaged academically and had positive perceptions of teaching practices and interactions with others, despite reporting fewer interactions with faculty and peers and less supportive campuses. These findings challenge institutions to continue to seek a deeper understanding of how adult learners engage with postsecondary education.
