KNUST tops world ranking for helping to achieve UN SDG 4 devoted to Quality Education

The Kwame Nkrumah University of Science and Technology (KNUST) is number one in the world for helping to achieve the United Nation's Sustainable Development Goal 4 (UN SDG 4) which is devoted to Quality Education.


The ranking was announced in the 2023 edition of the Times Higher Education Impact Rankings published on Thursday, June 1, 2023. 

The Times Higher Education (THE) Impact Rankings is the sole global performance tables that evaluate universities based on the United Nations' Sustainable Development Goals (SDGs). 

Employing meticulously calibrated indicators, the ranking provides comprehensive and impartial comparisons across four key areas: research, stewardship, outreach, and teaching.

The 2023 Impact Rankings, the fifth edition, encompassed a total of 1,591 universities from 112 countries.

Demonstrating unparalleled excellence, the KNUST secured the top position globally with an outstanding score of 93.1, surpassing all other universities worldwide in terms of providing quality education. 

The SDG 4 - Quality Education category evaluates universities' contributions to early years and lifelong learning, research, and their dedication to inclusive education. 

The 2023 feat is a massive improvement over the 2022 rankings which placed the University at number one (1) in Africa and 14th globally in terms of (SDG4).

Expressing his reaction to the latest ranking, Dr. Daniel Norris Bekoe, the University Relations Officer, highlighted that this remarkable achievement reflects the substantial and strategic investments made by the university's management over the years. 

In a press release issued on June 2, 2023, he praised the past and current administrations for massive investments in infrastructure, ICT, and e-learning resources, which he said had significantly enhanced the educational experience at KNUST.

“This significant achievement stands as a testament to the collective efforts and unwavering commitment exhibited by the entire KNUST community”, he said.

Impact Rankings 2023: quality education (SDG 4) methodology

This ranking focuses on universities’ contribution to early years and lifelong learning, their research on quality education and their commitment to inclusive education. Because early years provision and lifelong learning are not the main focus of education at universities, this table should not be used to assess the overall quality of teaching at a university.

View the methodology for the Impact Rankings 2023 to find out how these data are used in the overall ranking.


Research on early years and lifelong learning education (27%)

  • Proportion of research papers that are viewed or downloaded (10%)
  • Proportion of research papers in the top 10 per cent of journals as defined by Citescore (10%)
  • Number of publications (7%)

This focuses on research that is relevant to quality education, measuring paper views, the proportion of papers in the top 10 per cent of cited journals and the volume of research produced.

The data are provided by Elsevier’s Scopus dataset, based on a query of keywords associated with SDG 4 (quality education) and supplemented by additional publications identified by artificial intelligence. The data include all indexed publications between 2017 and 2021 and are normalised across the range using Z-scoring.

To understand how a university is supporting early years education, we measure the proportion of its graduates who receive a degree that would entitle them to teach at primary school level in their country. The data relate to the number of graduates in the 2021 academic year.

The data were provided directly by universities and normalised across the range using Z-scoring.

Lifelong learning measures (26.8%)

  • Free access to educational resources for those not studying at the university (5%)
  • Educational activities that are open to the general public, such as lectures or specific courses (5%)
  • Educational events that provide vocational training for those not studying at the university (5%)
  • Educational outreach activities in the local community, including schools (5%)
  • Policies to ensure that these activities are open to all, regardless of ethnicity, religion, disability, immigration status or gender (6.8%)

The evidence was provided directly by universities, evaluated and scored by THE and not normalised.

Proportion of first-generation students (30.8%)

This is defined as the number of students starting a degree who identify as being the first person in their immediate family to attend university, divided by the total number of students starting a degree. All data are provided as full-time equivalents.


The data were provided directly by universities and normalised across the range using Z-scoring.


When we ask about policies and initiatives – for example, the existence of mentoring programmes – our metrics require universities to provide the evidence to support their claims. In these cases, we give credit for the evidence, and for the evidence being public. These metrics are not usually size normalised.

Evidence is evaluated against a set of criteria, and decisions are cross-validated where there is uncertainty. Evidence need not be exhaustive – we are looking for examples that demonstrate best practice at the institutions concerned.

Time frame

In general, the data used refer to the closest academic year to January to December 2021. The date range for each metric is specified in the full methodology document.



The ranking is open to any university that teaches at either undergraduate or postgraduate level. Although research activities form part of the method­ology, there is no minimum research requirement for participation.

THE reserves the right to exclude universities that it believes have falsified data, or are no longer in good standing.

Data collection

Institutions provide and sign off their institutional data for use in the rankings. On the rare occasions when a particular data point is not provided, we enter a value of zero.

Two universities in Africa ranked first in individual SDGs

Two universities in Africa are included in the overall top 100 of the Times Higher Education (THE) Impact Rankings 2023, which are geared to assessing institutions’ contribution to the United Nations Sustainable Development Goals (SDGs), and two placed first globally for their contributions to individual SDGs, reports the University World News.

In the overall ranking, in which a total of 1,705 universities were assessed, two South African universities ranked highest in Africa: the University of Johannesburg (UJ) was placed in 46th position and the University of Pretoria (UP) in 69th place.

UJ was also placed first for the work it does in areas related to SDG 1 (no poverty).


The Kwame Nkrumah University of Science and Technology (KNUST) reigns first for its contribution to SDG 4 (quality education).

“It is gratifying to see that our university has once again been recognised for its significant contribution to societal impact, sustainability and innovation, through the SDGs. We are very proud of this achievement and excited to see even more outputs from our scholars in the near future.

“This is a testament to the outstanding work and dedication of our staff, postdoctoral fellows, students, research associates, research divisions, centres and institutes,” Professor Letlhokwa Mpedi, UJ’s vice-chancellor and principal, told University World News following the announcement.

According to him the university will continue to emphasise societal impact in what it does, including research on Global Excellence and Stature (GES) and the Fourth Industrial Revolution, “thus, GES 4.0 – for Societal Impact”.

In a media release the Kwame Nkrumah University of Science and Technology said: “Management expresses profound gratitude to the diligent staff and students, invaluable partners, and esteemed stakeholders for their immense contributions leading to this remarkable milestone. This significant achievement stands as a testament to the collective efforts and commitment displayed by everyone at KNUST.”

In addition to UJ and KNUST’s achievement, several other institutions also fared well in the work done in areas related to individual SDGs.

UP was placed 4th globally for SDG 8 (decent work and economic growth), and the University of Cape Town (UCT) 9th for clean water and sanitation.

According to the THE, South Africa has done well on SDG 8 (decent work and economic growth) with two universities in the top 10 – UP and UJ at 6th.

What is measured?

The THE ranking assesses commitment to sustainability across four broad areas: research, stewardship, outreach, and teaching based on self-submitted data from universities. However, a university’s ranking is based on its performance in SDG 17 – partnerships to achieve the goals – and three other SDGs, rather than across all the SDGs.

The ranking, now in its 5th year, is the world’s only one that specifically measures universities’ contributions to the SDGs although there are other rankings that assess universities’ contribution to sustainability, such as the QS World University University Ranking, and UI Green Metric.

Among the global regions, Western Sydney University, Australia (1st) was top overall in the world and Australasia; Queen’s University, Canada (3rd) was the top-ranked institution in North America; the University of Manchester, UK (2nd) came out on top in Europe; Universiti Sains Malaysia (up one place to 4th) was top in Asia; the National Autonomous University of Mexico (32nd) was first in Latin America and UJ in Africa.

The nine countries that participated in the rankings for the first time this year are Brunei, Curaçao, Ethiopia, Mauritius, Mozambique, Panama, Serbia, Syria and Zimbabwe.

Broader focus than traditional rankings

Universities in 115 countries were assessed.

Progress was measured for each of the individual 17 SDGs, and across the goals as a whole, which saw 18 universities from 10 countries and regions achieve number one positions.

Phil Baty, THE’s chief knowledge officer, said: “It moves away from the traditional and more narrow approach to rankings and looks at far broader issues – examining how universities are improving our world.”

To appear in the overall ranking table, universities must have submitted to SDG 17 (partnerships for the goals) and a minimum of three other SDGs. The total score was calculated as follows:

• SDG 17 – 22%
• Top scoring SDG – 26%
• Second best scoring SDG – 26%
• Third best scoring SDG – 26%

In addition, the score for the overall ranking is an average of the last two years’ total scores.

According to THE communications manager Ben Miller, this scoring measure was implemented for the first time this year to “increase the stability of the overall ranking, and to recognise the overall ranking's position as a broader assessment of a university's institution-wide commitment to sustainability in general”.

Baty said the impact rankings are an “extremely valuable tool” for universities, governments, funders, and policymakers to understand how universities are supporting the drive to meet the UN’s SDGs and what must be done to improve their performance even further in this massively important area.

He said that the rankings “are also vital for millions of prospective students who are increasingly demanding to see evidence that the universities they consider for their education are committed to sustainability and to helping them to become sustainably minded citizens”.
