This scoping review examined the literature on student well-being in two high-performing education systems, Finland and Hong Kong SAR. Seventeen articles published between 2004 and 2024 were identified and analyzed to map research trends and explore potential similarities and differences in student well-being outcomes. The review revealed that studies employed diverse methodologies and measures of well-being, making direct comparisons challenging. Preliminary findings suggest that students in both Finland and Hong Kong SAR report experiences of stress, anxiety, and depression. Trends over time and contributing factors varied across studies. This review highlights the need for future research employing standardized measures and methodologies to facilitate more robust comparisons of student well-being between these two distinct educational contexts. It also underscores the importance of considering sociocontextual factors when evaluating student well-being in international contexts.
