Internationally, first-year student experience surveys suggest that modern students are investing increasingly less time in their study at university, raising concerns about the impact this may have on their success. This paper describes a case study exploring student workload at a New Zealand university interested in understanding how student time allocation decisions are being made during actual weeks of study rather than hypothetical 'typical' weeks. The results show that the sampled students allocated time in line with university expectations. Time allocation on course work was significantly affected by assessment deadlines and by student achievement striving. Student grade point average was strongly correlated with time spent, and strongly influenced by students' beliefs regarding their motivation and self-efficacy. Universities are encouraged to explore mechanisms that support students being better informed about the implications of their choices, actively influencing their sense of priorities and expectations regarding the effort needed to be successful in their studies.
