University of Ibadan Retains Nigeria’s Top Spot in Latest Research Ranking

The University of Ibadan has retained its position as Nigeria’s leading university in the latest edition of the AD Scientific Index, strengthening its standing as one of the country’s most prominent research institutions.

The latest index, refreshed on October 1, 2026, places Nigeria 48th among 221 countries globally and third in Africa, with 384 Nigerian institutions and 53,580 scientists included in the database.

The findings were contained in a statement signed by the Chairman of the Nigerian Tertiary Education Ranking Advisory Committee, Emeritus Professor Peter Okebukola, on Friday.

UI Maintains National Leadership

According to the latest research-based ranking, the University of Ibadan remains in first position among Nigerian universities.

The institution was ranked 889th globally among nearly 19,800 universities, placing it within the top 4.5 per cent of universities included in the global ranking.

It was also ranked 14th in Africa.

The latest position represents an improvement from its global position of 904th in mid-August 2026 to 889th as of October 1.

The ranking further identified UI as the only Nigerian university within the global top 1,000 in the AD Scientific Index.

The university has also maintained its first-place national position across recent editions of the index, indicating sustained research visibility rather than a one-off movement.

Strong Presence of Federal Universities

One of the notable features of the latest ranking is the dominance of federal universities among Nigeria’s leading institutions.

At least eight of the country’s top 10 positions are occupied by federal universities.

The University of Nigeria, Nsukka, retained second position nationally, while the University of Lagos, Obafemi Awolowo University, University of Ilorin, Ahmadu Bello University, Nnamdi Azikiwe University and Bayero University were also listed among the country’s leading institutions.

The distribution is significant because it suggests that research strength is not restricted to one geographical area or a small number of institutions.

However, the dominance of federal universities should not be interpreted to mean that state and private universities lack research strength. Different ranking systems use different methodologies and indicators, and institutional performance can vary considerably depending on what is being measured.

Research Strength Behind UI’s Position

The latest figures also highlight the contribution of individual researchers to the University of Ibadan’s position.

UI has 1,586 indexed scholars, while five of its researchers appear among Nigeria’s 25 most-cited researchers in the latest assessment.

Mayowa Owolabi of the University of Ibadan was identified as Nigeria’s most-cited researcher, with 257,748 citations. He was placed 676th globally among more than 2.6 million indexed researchers.

Another UI researcher, Olayinka Ilesanmi, ranked third nationally with 185,602 citations.

These figures demonstrate how individual research output and citation impact can contribute substantially to the international visibility of a university.

Nigeria’s Research Footprint Is Expanding

The report also points to an expansion in Nigeria’s research presence internationally.

The number of Nigerian universities included in the AD Scientific Index has increased substantially from the 2024 edition, while the number of indexed Nigerian scientists has also risen.

The latest assessment records 53,580 Nigerian scientists, compared with 53,214 in November 2025.

Nigeria now has more indexed scientists than South Africa and Egypt, according to the report.

However, the figures also reveal an important challenge.

Nigeria’s researchers are distributed across a considerably larger number of institutions. The report estimates an average of about 140 indexed scientists per Nigerian institution, compared with 267 in South Africa and 387 in Egypt.

This means that increasing the number of researchers and institutions represented in international databases is only part of the challenge.

The next stage is improving the concentration, quality and global impact of research produced by Nigerian universities.

What the Ranking Actually Measures

It is important to understand what the AD Scientific Index ranking represents.

The index relies substantially on publicly available scholarly records, particularly Google Scholar profiles. It uses indicators including the H-index, i10-index and total citations to assess researchers and institutions.

Consequently, being ranked highly in this particular system primarily reflects research visibility and citation-related performance.

It should not automatically be interpreted as proof that one university is superior to another in every aspect of university education.

Teaching quality, student experience, infrastructure, graduate employability, professional training, funding, internationalisation and other factors may be assessed differently by other ranking systems.

This distinction is particularly important for prospective students and parents who may be tempted to treat a single university ranking as a complete measure of institutional quality.

Different Rankings Can Produce Different Results

The latest development also demonstrates why university rankings should be read according to their methodology.

For example, the 2027 Times Higher Education World University Rankings, released on October 1, placed Covenant University, the University of Ibadan and the University of Lagos in the same global 801–1000 band. The three institutions therefore share that global band, even though their positions and performance indicators differ.

This does not contradict the latest AD Scientific Index finding.

Rather, it demonstrates that different ranking organisations can produce different results because they measure different dimensions of university performance.

The AD Scientific Index places particular emphasis on researcher-level scholarly indicators, while broader university rankings use combinations of teaching, research, industry engagement and international outlook, among other measures.

Therefore, the statement that UI is Nigeria’s leading university should be understood within the methodology and edition of the particular ranking being discussed.

Obafemi Awolowo University Also Features

The latest AD ranking is particularly relevant to universities in South-West Nigeria because Obafemi Awolowo University, Ile-Ife, is among the Nigerian institutions highlighted in the leading group.

OAU also has researchers represented among Nigeria’s most-cited scholars.

The university’s inclusion reinforces the continued research contribution of major Nigerian federal universities outside the country’s commercial and political centres.

For students and researchers in Osun State, such rankings also provide an indication of the international visibility being generated by institutions within the region.

More Research Quality Needed

Despite the progress recorded, the report does not portray Nigeria’s research system as having reached its desired level.

Instead, it calls for greater concentration on research quality and impact.

The report specifically points to areas including citation impact, research output per academic staff, international collaboration and the number of Nigerian researchers represented among the world’s highly cited scholars.

It also recommends stronger doctoral training, support for highly cited research groups and improved international research partnerships.

These recommendations are important because a university’s research reputation is not built solely by producing a large number of publications.

The influence of those publications, their usefulness to society, their citation by other researchers and their contribution to solving practical problems are also important measures of research strength.

A Challenge for Nigerian Universities

The latest figures present both an achievement and a challenge for Nigeria’s higher education system.

On one hand, the country has increased the number of universities and researchers represented in international research databases.

On the other hand, the relatively low average number of indexed scientists per institution compared with some other major African research systems indicates room for deeper institutional research capacity.

Universities therefore need to move beyond simply increasing the number of publications.

Greater investment in laboratories, research grants, postgraduate education, academic collaboration, research infrastructure and international partnerships could help Nigerian researchers produce work with stronger global visibility and practical impact.

Rankings Should Be Used Carefully

University rankings can be useful tools for understanding trends in higher education, but they should not be treated as the only basis for choosing a university.

A prospective student considering UI, OAU, UNILAG, UNN, ABU, UNILORIN, a private university or another institution should examine the specific course, accreditation, teaching resources, facilities, cost, location, accommodation, graduate outcomes and opportunities available in the programme of interest.

A university may perform exceptionally in research while another may have particular strengths in industry partnerships, international outlook or another area.

The most useful approach is therefore to consider several credible indicators rather than relying on a single ranking.

Nigeria’s Research Future

The latest AD Scientific Index nevertheless provides evidence that Nigerian scholarship continues to gain international visibility.

The presence of more than 53,000 indexed Nigerian scientists and hundreds of institutions shows the scale of the country’s academic research community.

The continued performance of the University of Ibadan also demonstrates the value of maintaining strong research institutions over several decades.

The challenge now is to ensure that this progress extends across more Nigerian universities while improving the global impact of the country’s strongest researchers.

For UI, the latest ranking represents another recognition of its research strength.

For Nigeria, however, the bigger question is how to transform individual institutional successes into a stronger, better-funded and more internationally influential university research system.

The latest ranking therefore offers more than another list of universities. It provides a snapshot of where Nigerian research stands internationally—and a reminder of how much more can still be achieved.
