The ShanghaiRanking Consultancy has published its 2023 Academic Ranking of World Universities, highlighting what it deems to be the best 1,000 universities in the world – including eight located in South Africa.
The University of Cape Town (UCT) once again remains the best-ranked university in the country and is the only local institute to be ranked within the top 300 globally (201-300).
This is followed by the University of the Witwatersrand (301-400), with Stellenbosch University and the University of Pretoria in the next ranking range of 401-500.
The University of Johannesburg dropped back into the lower range in 2023 after being the only climber in 2022. It is now ranked 501-600, along with the North-West University and the University of KwaZulu-Natal.
Closing up the rankings is Unisa, within the 901-1000 range. The rankings do not factor in more recent developments in the local university space, such as Unisa potentially being placed under administration.
Instead, the ARWU uses six objective indicators to rank world universities:
- The number of alumni who win Nobel Prizes and Fields Medals (10%)
- The number of staff who win Nobel Prizes and Fields Medals (20%)
- The number of highly cited researchers in 21 broad subject categories (20%)
- The number of papers published in Nature and Science (20%)
- The number of papers indexed in the Science Citation Index-expanded and Social Sciences Citation Index (20%)
- The per capita academic performance of an institution (10%)
