This study aimed to compare the levels and relationships between school capacity, teacher capacity, and student experience in Thailand and Taiwan. Moreover, school types and school locations were examined to explore these differences. The secondary data from PISA 2018 were analyzed by quantitative approach. The results revealed that only school types had differences in teacher capacity in Thailand, whereas other demographic information did not. Other results showed different directions of correlations between school capacity, teacher capacity, and student experience. School capacity in both countries was able to predict teacher capacity. Other factors as predictors of the student experience are recommended.
