Differences with other university rankings

Compared with other university rankings, the Leiden Ranking offers more advanced indicators of scientific impact and collaboration and uses a more transparent methodology. The Leiden Ranking does not rely on highly subjective data obtained from reputational surveys or on data provided by universities themselves. Also, the Leiden Ranking refrains from aggregating different dimensions of university performance into a single overall indicator.

Improvements and new features

The CWTS Leiden Ranking 2013 includes a number of improvements and new features. In particular, the data collection methodology of the ranking has been extensively revised and statistics at the level of five broad fields of science have been added. New features include an indicator of university-industry collaboration and the possibility of excluding publications in special types of journals (e.g., non-international journals, trade journals, and popular magazines).

The CWTS Leiden Ranking 2014 will be released on April 30, 2014.
