South Africa’s Research Excellence Landscape Evolves
The National Research Foundation (NRF) rating system stands as a cornerstone of South Africa’s efforts to benchmark and elevate research quality. Established researchers undergo rigorous peer evaluation based on outputs and impact over the preceding eight years. Recent data reveal both encouraging expansion in the number of rated scholars and ongoing challenges related to geographic and institutional concentration.
Key Growth Metrics from 2020 to 2024
Between 2020 and 2024 the total pool of NRF-rated researchers expanded by 11 percent, reaching 4 728 individuals. This growth reflects sustained investment in human capital development across the higher-education sector. Younger researchers under the age of 40 now number 688, up from 526, although they still represent only 15 percent of the rated cohort.
Breakdowns by rating category show 134 A-rated scholars, 731 B-rated, 2 948 C-rated, 17 P-rated and 898 Y-rated researchers. The A-rated group, representing unequivocally leading international scholars, increased modestly from 124 to 134, with the majority of South African nationals within that group rising from 100 to 108.
Disciplines Driving Excellence
Health and medical sciences account for 24.3 percent of A-rated researchers, followed closely by biological and agricultural sciences at 22.6 percent. Prominent themes include infectious diseases, HIV/AIDS research, ecology and applied mathematics. Approximately 42 percent of A-rated scholars engage in interdisciplinary work, particularly bridging health, ecology and quantitative fields.

Regional Concentration Remains Pronounced
Western Cape and Gauteng provinces together host more than 80 percent of A-rated researchers, a distribution confirmed as statistically significant. The University of Cape Town and the University of the Witwatersrand together account for over half of this elite group. This pattern mirrors historical infrastructure advantages and continues to shape national research capacity discussions.
Institutional Performance Highlights
Leading universities continue to strengthen their rated researcher cohorts. The University of Johannesburg now hosts 347 rated researchers. The University of Fort Hare recorded an 82.8 percent surge, moving from 29 to 53 rated scholars. Central University of Technology and other institutions report steady gains across established and emerging categories.
Policy Implications and Capacity Building
The observed concentration underscores the need for targeted interventions. Policymakers and university leaders are exploring mechanisms to distribute research excellence more evenly. Initiatives include expanded research chairs, mentorship programmes and infrastructure support in historically disadvantaged institutions.

Interdisciplinary Trends and Future Outlook
The rise of interdisciplinary approaches among top-rated researchers signals a maturing research ecosystem. Continued growth in Y-rated and P-rated scholars offers optimism for the next generation. Sustained monitoring through NRF Data Insights publications will remain essential for tracking progress toward a more balanced and globally competitive system.
Stakeholder Perspectives
University administrators emphasise the prestige and funding advantages associated with higher NRF ratings. Early-career researchers highlight the motivational role of the Y and P categories. Government stakeholders stress alignment with national development priorities, particularly in health, agriculture and emerging technologies.
