How are the world’s best universities ranked, and what do systems like the QS World University Rankings consider in the top institutions?

Globally recognised and produced by Quacquarelli Symonds, a higher education publisher, the QS World University Rankings is one of the most widely read and reputable university ranking systems.

It has consistently based its ranking methodology on key metrics including academic reputation, employer reputation, faculty/student ratio, citations per faculty, international faculty ratio and international student ratio. Three new metrics were recently introduced—international research network, employment outcomes and sustainability. All metrics contribute a percentage towards an institution’s final score.

The results come from the analysis of millions of academic papers, and expert opinions of over 250,000 academics and employers.

QS ranking metrics explained

Academic reputation (30%)

Carrying the heaviest weightage, the academic reputation metric is based on a survey of faculty members, researchers, and professionals in academia from around the world, who nominate institutions based on academic excellence, research quality, impact and innovation.

Employer reputation (15%)

This metric evaluates the reputation of a university among employers, an indicator of employability of students. A survey sent to thousands of employers around the world collates their ratings of the best universities for producing relevant graduates.

Faculty/student ratio (10%)

QS looks at the ratio of faculty to students as an indicator of the learning and teaching environment in an institution. The more academic staff resource available to students, such as teaching and curriculum development, the better the experience expected.

Citations per faculty (20%)

To determine this metric, QS evaluates the number of academic citations in papers an institute produces, factoring in the size of the university, across a five-year period.

QS also performs a normalisation to keep the influence of research broadly equal for the different academic fields, considering that certain fields publish more papers than others.

International student ratio and international faculty ratio (5% each)

These metrics show how effective the institute is in attracting faculty members and students from all over the world. With a sizeable number of international faculty and students, an institution would offer a multicultural environment and benefits from diversity, networking and cultural exchanges.

International Research Network (5%)

An indicator of the quality of an institution’s research partnerships and collaborations on the international stage.

Employment outcomes (5%)

Another indicator of employability, this metric measures an institution’s graduate employment rate and alumni impact.

Sustainability (5%)

Recognising the importance of social and climate issues to students, QS became the first among the major world rankings to include sustainability as a key metric. It evaluates social and environmental impact, with governance factored in.

How to use rankings to decide where to study

The QS World University Rankings are one of the most trusted tools for comparing top universities globally, and provide valuable insights into an institution’s academic reputation, faculty quality, employer recognition and global outlook, which are areas to look into when choosing where to study.

However, rankings are just one part of it. Other crucial factors should be part of your decision-making process, such as tuition fees, career opportunities, university location and your personal goals.
