The Postsecondary and Adult Education topic supports research to improve the reading, writing, and numeracy skills of learners in adult education programs; the enhancement of targeted learning outcomes of postsecondary students; and the increase in access to, persistence in, and completion of postsecondary education. The long-term outcome of this research will be an array of tools and strategies (e.g., practices, assessments, programs, policies) that have been documented to be effective for improving education outcomes of adult learners (i.e., students at least 16 years old and outside of the K–12 system) and postsecondary students at the college level.
