The Shanghai ranking is limited to very few criteria, and these are often contested. It is particularly questionable that the number of Nobel Prizes held by alumni is a major indicator for the quality of teaching.

Nobel Prizes

The quality of research at an institution of higher learning is measured by the number of Nobel Prizes and Fields Medals; these indicators make up 30% of the overall ranking.
It is highly problematic that these prizes only recognize achievements in a narrow field of disciplines. Excellent achievements in many natural and social sciences – and especially in the arts and humanities – fall under the radar.
An additional problem is that these prizes were generally awarded decades ago. When considering Nobel Prizes awarded to alumni – whose student days are even farther in the past – the proxy becomes even less relevant. Clearly, the number of Nobel Prizes awarded does not make a conclusive statement about current research excellence. Yet another negative side effect of using this parameter is that older universities are generally at a greater advantage, as it is unlikely that a newly established university can quickly catch up on the number of Nobel Prize winners it educates or employs.

Thomson Reuters is source of data

Many critics point out that the data basis used by Thomson Reuters (Web of Science) is not representative of research achievements in many disciplines: the database contains only a limited type of publication (mainly articles in journals), while completely ignoring other important publications (e.g. monographs). Furthermore, journals and publications in English are heavily favored, with the result that research achievements in other languages are underrepresented. Finally, the indexes in the database disregard differences in publishing practices in the various disciplines.

Per capita performance

The Shanghai Ranking also only makes an adjustment of 10% for the size of a university. In 90% of all assessments, big, well-connected universities are at a major advantage when measuring research output.


UZH believes the Shanghai Ranking does not live up to its own goal of making an objective assessment of universities. Its small number of highly problematic indicators and its non-representative bibliometric basis reduce the value of the results and, consequently, of any statements regarding the quality of research and teaching at universities.
