Existing studies have revealed that prior educational experience plays an important role in student learning, and many international students are encountering challenges while undertaking academic studies at Anglophone universities. However, few studies have examined how the pre-university preparation international students experience assists them in transitioning to university. This study explores, through the perceptions of students, the effectiveness of different university preparation pathways of a cohort of international students in a leading Australian university. Using a mixed-method research design, a questionnaire and focus group interviews were conducted to collect data about overseas student perceptions of the pathway program they undertook. The results show that international students who undertook different pathway programs had different perspectives about the extent to which they felt prepared for university in terms of important aspects of their education, such as subject content knowledge and English language proficiency. Based on the students' perceptions, the findings of this exploratory study contribute new insights to help improve education practices at universities through a deeper understanding of the diverse preparation international students receive. Overall, the article highlights the heterogeneous nature of international students' academic preparedness for university transition, and offers some practical implications for university educators, administrators, and curriculum designers.
