Established in 2004, the London-based ranking system aims to help students identify leading universities overall and in particular subjects around the globe.

Universities are ranked according to their performance by indicators of academic excellence, including students' employability after attending the school, each school's International Research Network and how each university is tackling environmental, social and governance issues, according to the ranking methodology.

“Although (Korea) confronted a decline in the school-age population, (the country) will be able to overcome the situation with its excellent higher education system,” said Ben Sowter, senior vice president at the rankings.

“Korea showed a high-performance level on par with Germany, Japan and France, which have larger populations and economies (than Korea),” he added.
