Harvard University was ranked best university, followed by Stanford University and Massachusetts Institute of Technology, according to the Center for World University Rankings.
The list ranks universities based on seven factors, without relying on surveys or university data submissions: quality of teaching, alumni employment, quality of faculty, research output, quality of publications, influence and citations.
South Korea’s Seoul National University dropped to 60th place, from 23rd. The University of Science and Technology entered the list for the first time this year, at 183rd place.
