Fourteen boys crowded into one dormitory room for sleep and study, showing the need for more space in Korean schools. Thirteen hundred boys applied for admission in April of 1922, but only two hundred could be admitted. Pyeng Yang High School operated as an American Presbyterian mission school, and was closed in 1940 with the greater militarization of Korea. Mrs. Ruth Bell Graham, wife of evangelist Billy Graham, attended this school in the 1930s.
