Mature-age students are a significant group within the Australian sub-degree and undergraduate commencing cohort. Nevertheless, little is known about mature-age student backgrounds or factors that affect their participation at university. This paper draws on a case study that examined the nature and outcomes of Australian alternative entry programs for mature-age students. Specifically, the paper explores the demographic characteristics of mature-age students who participate in these programs. Australian research indicates that mature-age student circumstances influence their university aspirations and awareness of academic study. An understanding of mature-age student characteristics assists program organisers in designing effective alternative entry courses for unmatriculated, return-to-study and equity group mature learners. It is through a shared knowledge of mature learner circumstances and appropriate pedagogy that alternative entry program personnel can monitor and advance student participation at university.
