This is the first study that examines the comparative validity of the Chinese National College Entrance Exam (known as Gaokao) to a Western end-of-secondary-school performance measure, Australian Tertiary Admission Rank (ATAR), as admission criteria to an Australian undergraduate degree programme. The study offers a strong warning about using just an aggregate Gaokao score as a sole admission criterion. However, the findings suggest that with adjustments for gender and time, Gaokao is found to be as good an admission criterion as ATAR, hence justifying its use for selection purposes if such adjustments are made. Supplementing selection criteria by also using the Gaokao English result is found to be a further improvement. The findings can help inform the admission policy relevant to Chinese international students into undergraduate degree programmes globally.
