Editor notes – World University Rankings 2016

Times Higher Education is committed to transparency and accountability across all of its rankings.

The data used to create the THE World University Rankings and the portfolio of regional and specialist rankings comes from three sources: reputational data from THE’s annual Academic Reputation Survey, institutional data supplied to THE directly by the universities themselves through our secure data collection portal, and bibliometric data provided by Elsevier, from its Scopus database. These data combine to form the 13 performance indicators used to create the World University Rankings.

January 2016 update

Following the publication of the 2015-16 World University Rankings, Aarhus University notified us that they had submitted inaccurate data. The data error, which was not picked up in our quality control processes, disadvantaged Aarhus in the rankings. We have corrected the data and recalculated the ranking, and this has resulted in Aarhus obtaining a position of joint 106th (up from joint 149th). We have moved Aarhus to the joint 106th position, but we have retained the original ranking places for all other institutions.

It has also emerged that incorrect bibliometric data were supplied to THE by Elsevier for the University of Palermo, Argentina, and included some publication data for the University of Palermo, Italy. Unfortunately, when using correct data, the University of Palermo, Argentina, does not meet THE’s threshold for inclusion*. The data has now been corrected and the University of Palermo, Argentina, no longer appears in the rankings.

* Our bibliometrics threshold is 1,000 papers (and at least 200 papers a year) published in journals indexed by Scopus, between 2010 and 2014.

March 2016 update

An error relating to the calculation of Purchasing Power Parity (PPP) in the financial data for a small number of institutions has been corrected, which has positively affected the ranking position of six institutions in the 2015-16 rankings.

We use PPP so that comparisons between universities in different countries are fairer. In total, 13 of the 1,126 institutions which submitted data for the 2015-16 rankings submitted financial data in a currency other than their own national currency, resulting in an incorrect PPP calculation. The correction led to a rankings position change for six of the 13 institutions.

An error was also identified for one other institution, meaning seven universities have changed position. We have corrected the data and recalculated the ranking, and this has resulted in changes for the University of São PauloTechnion Israel Institute of TechnologyBoğaziçi University, the Moscow Institute of Physics and TechnologyNational Research Nuclear University MePhI, the University of Iceland, and Paris-Sorbonne University - Paris 4. No other 2015-16 rankings positions have been affected.
