Student retention is of key importance to many private higher education institutions in Malaysia. This paper discusses the factors influencing a selected group of former pre-university students' decision to continue their undergraduate studies in the same university where they had completed their pre-university studies. In-depth interviews were conducted, and three major themes of student retention were identified namely, the educational quality at the institution, educational quality at pre-university level and the overall conducive study and support environment. The findings provide insights on retention related challenges and issues faced by this group of students. This study also suggests ways on how the university could successfully improve its student retention.
