The Georgia Institute of Technology was No. 33 on the list. Last year, it had the same ranking, tying with Australia's University of Melbourne, which is No. 32 this year.

Emory University was No. 98, down 16 spots from the previous year. Last year, it tied with Dartmouth College, the U.K.'s University of Warwick and Germany's Technical University of Berlin, which placed 89th, 91st and 92nd, respectively, this year.

According to the Times website, the global university ranking is the only one of its kind to judge a multitude of world class universities across several core missions.

Analysts examined 1,000 institutions from 77 countries and scored them based on 13 calibrated performance indicators grouped in five categories, including teaching, research, citations, international outlook and industry income.

Indicators such as staff-to-student ratio, reputation survey and international collaboration were among the 13 studied.

Both Georgia universities are consistently recognized as prestigious colleges and have ranked among the nation's best universities, the South's best colleges and the best in Georgia in multiple studies.

According to the Times Higher Education ranking, the best university in the world is the University of Oxford, which took the top spot last year as well.
