School rankings can help you compare universities, but each ranking measures different things. Learn what QS, THE, and ARWU actually measure, what rankings miss, and how to use them wisely.
A university can rank in the top 100 in one list and much lower in another. That is not a mistake. It happens because each ranking uses its own formula. This guide helps you read rankings the smart way, so they support your decision instead of making it for you.
Compare programs, not just rankings

What the Major Global Rankings Measure
The three best-known global rankings are QS, Times Higher Education (THE), and ShanghaiRanking's Academic Ranking of World Universities (ARWU). Each one rewards different strengths.
Note: Because each ranking uses a different formula, the same university can appear in very different positions. A school that is strong in research may rank high on ARWU, while a school with a strong global reputation may do better on QS. Neither tells you how good a specific program is for you.
Overall Rankings vs. Subject Rankings
Overall rankings judge a whole university. But you will study one program. QS and THE both publish subject rankings that compare universities in specific fields, such as computer science, business, or nursing. A university that ranks lower overall may be one of the best in your subject. If you use rankings at all, subject rankings are usually more useful.
What Rankings Do Not Tell You
Global rankings leave out many things that matter to international students:
- Teaching quality in your program: Rankings focus mostly on research and reputation, not how well your classes are taught.
- Cost and value: Rankings do not consider tuition, living costs, or scholarships.
- Career outcomes in your field: A high overall rank does not guarantee jobs in your area.
- Support for international students: Orientation, counselling, and career services are not measured.
- Visa and post-study work options: These depend on the country and program, not the ranking.
- Colleges and polytechnics: Most global rankings only include research universities. Excellent colleges, polytechnics, and applied institutions are usually not ranked at all.
Check Official Recognition First
Before you look at any ranking, make sure the school is officially recognized and allowed to enrol international students. This matters more than any ranking, because it affects your visa and whether your qualification will be accepted.
For Germany, Spain, Singapore, and the UAE, check the official list of recognized institutions with the national education authority, or ask your ApplyBoard expert. ApplyBoard only works with recognized institutions.
Warning! Be careful with claims like "ranked number one" in advertising. Ask which ranking, which year, and which subject. Some lists are paid promotions or use very narrow measures. A trustworthy school will tell you exactly where a ranking comes from.

How to Use Rankings the Smart Way
- Start with your own priorities. Decide what matters most to you, such as cost, location, career outcomes, or work placements, before you look at rankings.
- Use subject rankings, not just overall rankings. They are closer to what you will actually study.
- Compare more than one ranking. If a school does well across several lists, that is a stronger signal than one high position.
- Look at ranges, not exact positions. The difference between number 150 and number 180 is usually very small.
- Check official outcome data. Tools like Discover Uni (UK) and QILT ComparED (Australia) show real graduate results by course. See how to use outcome data.
- Treat rankings as one input, not the answer. Use them to add schools to your list, not to rule out good options.
Frequently Asked Questions
Some do, especially in competitive fields like finance, consulting, and research. But most employers care more about your skills, work experience, and the relevance of your program. A strong program with good work placements often matters more than a school's overall rank.
Most global rankings are built around research output, so they mainly include research universities. That does not mean an unranked college or polytechnic is poor quality. Many offer excellent practical training and strong job outcomes.
No single ranking is the best. Each one measures different things. Choose the ranking that measures what you care about, read its methodology, and compare it with others. Subject rankings and official outcome data are usually the most useful for students.
Rankings are a useful starting point, but they are only one piece of the picture. The best school for you is the one that is officially recognized, strong in your subject, affordable for your budget, and able to support your career goals.
