This report examines how higher education institutions define and describe undergraduate-adult learners, why it matters, and explores creating a common definition for the undergraduate-adult learner. The survey upon which this report was based was conducted to benchmark U.S. higher education and the American Association of Collegiate Registrars and Admissions Officers (AACRAO) member practices and challenges faced by institutions in their efforts to recruit, retain, and provide services for undergraduate-adult learners.
