US News & World Report has published its 2022 Best Global Universities rankings, which includes a list of the top 13 tertiary learning institutions in South Africa – 10 of which, including Unisa, are ranked among the top 900 in the world.
For the second consecutive year, the rankings placed Unisa at 9th in the country and 851st globally, up from 921st in the previous year.
Nine SA universities saw their global position improve, while four dropped down the ranking.
The overall ranking encompasses 1 750 top institutions, up from nearly 1 500 last year, and spread across more than 90 countries, up from 86 last year.
The University of Cape Town remains the top university locally and in Africa. However, it dropped from its highest point on the listing at 103rd, to 109th.
