QS Ranking system
QS World University Rankings are annual university rankings published by British Quacquarelli Symonds (QS). The publisher originally released its rankings in publication with Times Higher Education (THE) from 2004 to 2009 as the THE-QS World University Rankings, but such collaboration was terminated in 2010, with the resumption of publishing by QS using the pre-existing methodology in the aftermath of new cooperation between Times Higher Education and Thomson Reuters releasing Times Higher Education World University Rankings. Today, the QS rankings comprise both world and regional league tables which are independent of and different from each other owing to differences in the criteria and weightings used to generate them. The publication is one of the three most influential and widely observed international university rankings, alongside the Times Higher Education World University Rankingsand the Academic Ranking of World Universities
The THE-QS ranking uses six indicators: academic peer review; employer review; faculty to student ratio; citations per faculty member; proportion of faculty that are international; and proportion of students that are international.
