Understanding UCT’s latest ARWU ranking

Dear colleagues and students

The latest Academic Ranking of World Universities (ARWU) has been released, and the University of Cape Town (UCT) remains the top ranked university in Africa.

UCT has been ranked 286th globally in the 2026 ARWU, released on Sunday, 16 August 2026. This represents a movement from 258th in 2025.

I recognise that a movement of 28 places may raise questions, particularly given the importance we place on UCT’s research excellence and international standing. It is therefore important to look beyond the headline position and understand what the underlying data tells us.

ARWU is one of the world’s most research-intensive university rankings. It focuses heavily on research achievements and research output, including Highly Cited Researchers, publications in Nature and Science, Web of Science-indexed publications, major academic awards and per-capita academic performance.

The 2026 result presents a mixed picture of UCT’s performance.

Our score for Highly Cited Researchers increased from 2.9 to 3.3, while our Alumni score remained unchanged at 1.6. Three indicators declined: our score for Web of Science-indexed publications moved from 7.3 to 6.7; the Nature and Science indicator moved from 2.8 to 2.7; and per-capita academic performance moved from 1.8 to 1.7.

ARWU scores are relative measures, benchmarked against the highest-performing university on each indicator. A change in an indicator score therefore does not necessarily mean that UCT’s absolute research output has fallen by the same proportion – or even that it has fallen at all. It means that our performance on that measure has changed relative to the global benchmark.

The data periods used by ARWU also change between editions. The publication indicator in the 2026 ranking uses publications from 2025, while the previous edition used publications from 2024. The Nature and Science indicator uses a five-year window, and the Highly Cited Researchers indicator uses the latest Clarivate data.

It is also important to consider ARWU alongside other international benchmarks. In the QS World University Rankings 2027, UCT ranked 184th globally and first in Africa. In the Times Higher Education World University Rankings 2026, UCT ranked 164th globally and first in Africa, with particularly strong performance in its research-quality and research-environment measures. The latest CWUR 2026 placed UCT 276th globally and second in Africa.

Each ranking measures different dimensions of university performance. ARWU is particularly concentrated on research achievements, highly cited researchers and publication output; while QS, THE and CWUR incorporate different combinations of research, reputation, teaching, internationalisation, employability and other measures.

For UCT, the ARWU result provides both reassurance and areas for further attention.

Our strong performance in the Highly Cited Researchers indicator is evidence of the continued international influence of our research community. Our Alumni indicator remains particularly strong, with UCT ranking 104th globally on this measure. At the same time, the movement in the publication and per-capita indicators gives us useful information about areas that warrant closer analysis.

We should take those signals seriously. At the same time, we should not lose sight of the broader picture: UCT remains among the world's leading research-intensive universities, continues to lead Africa in several major global rankings, and continues to produce research of international significance.

Our purpose is to produce excellent scholarship, educate outstanding graduates and generate knowledge that contributes meaningfully to South Africa, Africa and the world. But rankings can provide useful comparative evidence of where we are strong and where there is an opportunity to do better.

We seek to sustain UCT’s excellence while ensuring that our scholarship has relevance and impact beyond the university – contributing to a fairer and more just society. We urgently need to make progress on our Strategy 2030 interventions to ensure that we remain a leading institution in a world where the higher education landscape has become much more competitive.

I would like to thank our staff and students for the contribution each makes to UCT’s research and academic enterprise. The international standing reflected in these rankings is ultimately the product of the collective work of our community.

We will use this result constructively: recognising the strengths it confirms, understanding the areas where we can improve and continuing to create the conditions in which excellent and impactful research can flourish.

Sincerely

Professor Mosa Moshabela
Vice-Chancellor
