Against the background of expanding parental choices and declining global birth rates, schools are experiencing rising competition regarding student enrolment. Schools have responded by strategically presenting information about their students’ academic achievement and whole-person development orientation in the hope of attracting parents’ interest. However, few studies have investigated the impact of these factors on student enrollment, particularly in the context of diverse school types and educational orientations. Accordingly, this study utilized data from 327 secondary schools in Hong Kong to examine the effects of academic achievement orientation and whole-person development orientation on student intake. Using hierarchical regression analysis, we found a positive association between high whole-person development orientation and student intake in aided schools with a strong academic development orientation. The result implies parents are increasingly concerned about their children’s academic achievement and whole-person development at school. The study contributes to a broader understanding of the factors influencing parental choice in high-performing education systems, providing valuable insights for policymakers and educators seeking to improve educational offerings, enhance school transparency, and be better aligned with parental expectations.
