This paper is a study on the social characteristics of Go-deung-bo-tong school students in the 1920s-1930s. At that time the Go-deung-bo-tong school students had a scarcity value for its small numbers, and this suggests that the Go-deung-bo-tong school students are different from the present secondary school students. I have analysed ages, the process of educational selection, economic stratification of Go-deung-bo-tong school students, which are considered to reveal the characteristics of the group. The result shows that most of Go-deung-bo-tong school students were adults in terms of social age classification, a special group of people that was selected through an intensive competition, and from the propertied class. Some students had various educational backgrounds and social experiences. For this reason, Go-deung-bo-tong school students had the characteristics of adults and elites. So they were people who had intellectual abilities and rich experiences to penetrate the issues of education and society. These intellectual abilities and rich experiences made them resist against the Japanese colonial dominance and be in active such as ``vnarod movement``.
