Leiden Ranking: Many Ways to Rate Research
My article on the Leiden Rankings in University World News can be found here.
It looks as though a two-tier international university ranking system is emerging.
At the top we have the 'big three', Shanghai's Academic Ranking of World Universities, the QS World University Rankings and, since 2010, the Times Higher Education World University Rankings.
These receive massive attention from the media, are avidly followed by academics, students and other stakeholders and are often quoted in promotional literature. Graduation from a university included in these has even been proposed as a requirement for immigration.
Then we have the rankings by SCImago and Webometrics, both from Spain, the Performance Ranking of Scientific Papers for World Universities produced by the Higher education Evaluation and Accreditation Council of Taiwan, and the Leiden Ranking, published by the Centre for Science and Technology Studies at Leiden University.
These rankings get less publicity but are technically very competent and in some ways more reliable than the better-known rankings.
