Academic Ranking of World Universities
The Shanghai Ranking is considered the most recognizable and prestigious international ranking. It is based on a relatively small number of indicators. ARWU uses six objective indicators to rank world universities, including the number of alumni and staff winning Nobel Prizes and Fields Medals, number of highly cited researchers selected by Clarivate Analytics, number of articles published in journals of Nature and Science, number of articles indexed in Science Citation Index - Expanded and Social Sciences Citation Index, and per capita performance of a university. More than 1800 universities are ranked by ARWU every year and the best 1000 are published.
Only two Polish universities are among the 500 best universities in the world - the University of Warsaw and the Jagiellonian University. In 2018 the number of HEIs included in the ranking was increased to 1000 and 12 Polish universities were on the list, including Lodz University of Technology. In 2019 there were only 9 Polish HEIs and in 2020 – 8 HEIs. Unfortunately, in the latest edition of the ranking all Polish universities, except for University of Warsaw, have recorded a decrease.
