Numerous UK higher education institutions (HEIs) offer bioscience foundation years to assist students who may not meet standard entry requirements, thereby aiding widening participation initiatives. This paper aims to explore the motivations, rationale, and expectations of students in a biosciences foundation programme, to support understanding and subsequent development of this student group. The study revealed that students are primarily driven to pursue a bioscience foundation year to enhance their career prospects and foster intellectual development. These motivations were also evident in their decision to choose a foundation bioscience degree, where career opportunities and genuine interest in the subject matter played significant roles. The findings from this study may assist educators and institutions in providing better support to help students achieve their academic and career aspirations.
