The term is widely used nationwide in Korea, in the Korean broadcast media and even by the universities themselves. Regardless of the academic standing of the SKY universities internationally, inside Korea, admission to one of them is widely considered as determining one's career and social status. Many Korean politicians and policy makers have a degree from a SKY university. The President's cabinet is usually filled with SKY graduates (predominantly from Seoul National University).
