This chapter examines the evolution of holistic admissions in Singapore, outlining the motivations and rationale behind the admissions policies adopted by the nation's universities across three key periods. Each period reflects a distinct admissions model: a focus on academic performance until the early 2000s, the introduction and adoption of the Discretionary Admissions Scheme (DAS) in the late 2000s, and the transition to the Aptitude-Based Admissions (ABA) approach in the late 2010s. The chapter provides a comprehensive analysis of these policies, exploring their formulation and the perspectives of various stakeholders, including parliamentarians, university administrators, students, and parents. We discuss the implications of holistic admissions on higher education in Singapore broadly, and present findings from previous research on its impact on the diversity of the student body and the outcomes of students admitted through these policies. The chapter also highlights potential challenges arising from the shift toward holistic admissions.
