There are many factors that go into determining a university’s position in global rankings, some obvious and some less so. This guide looks at the main rankings, what they value in a university, and how you can use this information to find a university better suited to you.
Because indicators are weighted differently, and sometimes measured differently, the same university can be “excellent” by one model and merely “strong” by another. Rather than telling you how these rankings should be interpreted, this guide simply lays out the information so that you can decide for yourself which criteria matter most. For the exact component weights used by each ranking system, please check the official pages of each ranking system.
The QS World University Rankings, one of the most widely used systems across Europe, use a mixed model that combines reputation surveys, bibliometrics, and proxies like internationalisation and sustainability. This weighting means that a university can climb significantly on reputation and employment outcomes alone, with reputation and employment outcomes accounting for 50% of the score, while research accounts for 20%. Internationalisation, sustainability, and the student-to-faculty ratio make up the remaining 30%. It is important to note that the QS World University Rankings by Subject use different ranking criteria, with a heavier focus on citations and reputation.
THE is particularly useful if you care about a university’s research environment and influence, with 59% of its weighting tied to research-related indicators, while still placing substantial emphasis on teaching quality, which accounts for 29.5%. International outlook and industry make up the remaining 11.5%.
Shanghai’s ARWU is the most “old-school” global ranking in the sense that it is overwhelmingly about research prestige and output, with no reputational survey and very limited attention to teaching proxies. It considers criteria like alumni and staff who have won Nobel Prizes and Fields Medals, which account for 30%, and places a heavy focus on STEM subjects, including 20% for papers published in Nature and Science.
Alongside the global rankings, UK students commonly use domestic tables, which tend to be more student-oriented. The Guardian explicitly builds its subject tables from student lifecycle metrics such as satisfaction, staff ratios, spend per student, continuation, value-added, and career outcomes. The Times combines several indicators, including satisfaction, outcomes, entry standards, research, and sustainability, into both overall and subject views. The Complete University Guide is also widely used for its broad, multi-measure approach, which includes satisfaction, entry standards, research measures, graduate prospects, completion, and spend metrics.
QS Best Student Cities is designed to rank the places where institutions are located, making it a useful supplement to university tables that ignore the lived environment around a campus. It aggregates indicators across themes such as university quality, student mix, employer activity, affordability, and a student voice component derived from student survey responses. It is a useful guide when choosing universities; however, I would still recommend visiting in person if possible.
Ultimately, rankings are best used to understand how universities perform under different models of “excellence”, not as a definitive authority on the exact ranking of any institution. Crucially, many decisive factors sit outside any methodology: the city’s cost of living, housing availability, transport, safety, community, and cultural life can shape your experience as much as any metric. Tools like QS Best Student Cities help to bring place back into the picture, but the most reliable test is still a practical one: if you can, visit, walk the campus, explore the neighbourhoods students actually live in, and speak to current students.
