Persistent prejudice and a growing sense of social distance toward North Korean refugees have become significant obstacles to their integration into South Korean society. South Korean unification education has, thus far, not provided an effective response to this challenge. This case study introduces the North-South Forum as a potential solution and evaluates its impact on 135 middle school students. Changes in social distance, prejudice, and perceived difference toward North Korean refugees were measured through surveys conducted before and after the program. The results show, for the first time in a Korean setting, that intergroup contact leads to statistically significant improvements in students’ social distance, perceptions, and feelings of difference. The findings indicate that the North-South Forum has the potential to serve as a valuable addition to unification education, contributing to social integration as a step toward Korean unification. Regional and gender-specific patterns observed in the data warrant further research.
