The international education in Taiwan has continued for years, but its results after implementation were rarely evaluated. In this study, an elementary school which has implemented five-year international education was selected, and its international education was evaluated on the spot via 33 measures in five dimensions - school internalization, curriculum integration, international education travel, student learning growth and teacher professional development. Both qualitative and quantitative methods were adopted for evaluation data collection, including student recognition evaluation. The study found that curriculum integration, international education travel and teacher professional development evaluation results are good; school internationalization and student learning growth needs to be strengthened. Finally, this study proposes international education recommendations for other schools.
