How to Read University Rankings Without Being Misled: QS, THE, Shanghai and U-Multirank Compared
By Muntasir Minhaz • Published Jul 21, 2025 • Guides, Study in Europe
QS, Times Higher Education (THE), Shanghai Ranking (ARWU), and U-Multirank each measure different things, so the same university can hold a different position in each one.
QS weighs reputation surveys of academics and employers heaviest, plus research citations and internationalization.
THE splits its score across teaching, research quality, research environment, international outlook, and industry income, at roughly 30/29.5/29/7.5/4 percent.
ARWU (Shanghai Ranking) counts Nobel Prizes, Fields Medals, and highly cited researchers, so it favors old, large research universities.
U-Multirank doesn't produce one ranked list. It lets you compare universities across five separate categories you choose yourself.
Check a programme's subject-specific ranking, not only the overall university position, before you decide.
Why the same university ranks differently everywhere
Global rankings measure different things and weight them differently, so comparing a university's QS position to its THE or Shanghai position tells you little on its own. Read the methodology behind any ranking before you trust its order, since the indicators decide what "best" actually means in that particular table.
| Ranking | Weighs most heavily | Best used for |
|---|---|---|
| QS | Academic and employer reputation surveys | International name recognition |
| THE | Research quality and research environment | Research-intensive universities |
| ARWU (Shanghai) | Research prizes, citations, publication volume | Long-term research prestige |
| U-Multirank | Whatever dimensions you select | Comparing specific criteria like teaching or regional links |
QS World University Rankings
QS builds its score mostly from reputation. Academic and employer reputation surveys, gathered from hundreds of thousands of respondents worldwide, carry the largest combined weight in the QS methodology, followed by research citations per faculty member, faculty-to-student ratio, and international student and staff numbers. QS added employability outcomes, sustainability, and international research network measures to its methodology in 2023, reducing the weight given to the older indicators. Because reputation surveys count so heavily, QS tends to favor universities with long-established international name recognition over younger institutions with strong but less visible research. Check the QS methodology page directly for the exact current weightings, since QS revises them most years.
Times Higher Education World University Rankings
THE splits its score across five pillars, according to its published methodology : research quality at 30 percent, teaching (the learning environment) at 29.5 percent, research environment at 29 percent, international outlook at 7.5 percent, and industry income at 4 percent. Research quality covers citation impact and research strength, while teaching combines a reputation survey with staff-to-student ratio and institutional income. Because research output and citations dominate the score, THE tends to favor large research-intensive universities with strong publication records, similar to QS but with less weight on employer opinion.
Shanghai Ranking (ARWU)
The Academic Ranking of World Universities, known as ARWU or the Shanghai Ranking, counts research prestige almost exclusively. Its published methodology weighs alumni who won Nobel Prizes or Fields Medals at 10 percent, staff who won the same prizes at 20 percent, highly cited researchers at 20 percent, papers published in Nature and Science at 20 percent, total papers indexed in the Science and Social Science Citation Indexes at 20 percent, and per capita academic performance at 10 percent. No survey data and no teaching measure appear anywhere in ARWU. It rewards decades of accumulated research prestige, so it favors old, large, science-heavy universities and rarely moves much year to year.
U-Multirank: comparison without a single league table
U-Multirank takes a different approach. Instead of one ranked list, it scores universities across five separate dimensions: teaching and learning, research, knowledge transfer, international orientation, and regional engagement, then lets you build your own comparison by picking which dimensions matter to you. A university can rank at the top for teaching and mid-table for research in the same tool. Try U-Multirank directly if you want to compare specific criteria like class size or graduate employment rather than one blended score.
Subject rankings use different weightings than overall lists
QS and THE both publish separate subject and regional rankings alongside their overall world rankings, and these use their own weightings rather than the overall formula. QS subject rankings, for example, weigh academic and employer reputation surveys even more heavily than the overall list, since a smaller, subject-focused audience of academics knows a specific department's reputation better than they know a whole university's. Always check whether a number you're looking at comes from the overall world ranking or a subject-specific one, since the two lists for the same university sometimes disagree by a wide margin.
How to use rankings without being misled
Check the subject-level ranking for your specific field before you look at the overall university position, since a university strong in medicine ranks poorly overall sometimes, and the reverse also happens. Read what each ranking actually rewards: reputation surveys favor famous, established names, citation counts favor large research output, and prize counts favor decades of accumulated prestige rather than current teaching quality. Treat rankings as one input next to accreditation status, programme content, and graduate outcomes data, not the deciding factor.
