Daewon, Goyang, Sangsan, and Yongin High Schools each produced at least 200 of the 2012 school year’s admittants to the SKY schools (Seoul National University, Korea University, and Yonsei University). That places them in the so-called “SKY 200” club. Of the top ten high schools for producing SKY admittants, only one is not a foreign language high school — Sangsan High School.
One in five SKY admittants comes from a foreign language high school this year, continuing a long-standing trend, but the rate actually fell this year. After rising from 28.4% in 2009 to 32.2% in 2010 and 33.4% in 2011, the rate this year was 31.3%.
Experts say this is due to the expanding applicant pool and the CSAT becoming easier, reducing the merits of foreign-language high school graduates. The study analyzed the past six years of SKY admittant pools from 39 foreign language, international, and open high schools.
