ARWU ranking uncertainty and sensitivity: What if the award factor was Excluded?

The A cademic R anking of W orld U niversities ( ARWU ) uses six university performance indicators, including “Alumni” and “Awards”—the number of alumni and staff winning Nobel Prizes and Fields Medals. These two indicators raised doubts about the reliability of this ranking method because they are difficult to cope with. Recently, a newsletter was published featuring a reduced ARWU ranking list, leaving out Nobel Prize and Fields Medal indicators: the Alternative Ranking (Excluding Award Factor). We used uncertainty and sensitivity analyses to examine and compare the stability and confidence of the official ARWU ranking and the Alternative Ranking. The results indicate that if the ARWU ranking is reduced to the 4‐indicator Alternative Ranking, it shows greater certainty and stability in ranking universities.
