Gwangju students have the best CSAT English scores.

So says the Korea Institute for Curriculum and Evaluation via the Korea Times:

The government released details of the results of college scholastic ability test (CSAT) across the nation for the first time ever Wednesday, showing a wide performance gap among regions. The disparity drew concerns that harsher competition could worsen it.

Gwangju Metropolitan City, in the far south of the Korean peninsula, topped the list in foreign languages, English, and social science for five consecutive years, according to the education ministry. About 49 percent of students there were above grade four from a total of nine grades, which is roughly equivalent to being in the top 40 percent.

The disclosures are controversial because they list the results by region and school, a practice which, critics say, could be used to unfairly measure the quality of schools and administrators.
