When you start researching options to study abroad, global university rankings are almost always your first port of call. Names like the QS World University Rankings, Times Higher Education (THE), or the Shanghai Ranking appear in nearly every forum and information leaflet.
It is easy to be impressed by the numbers and assume that a university ranked at number 50 is automatically the right choice for you, while one at number 150 should be dismissed.
However, looking blindly at rankings is one of the biggest mistakes an international student can make. To make an intelligent decision, you need to understand the scenes behind these figures and what they actually evaluate.
What Do Rankings Really Measure?
Global rankings do not measure “student happiness” or the “quality of practical teaching”. They are calculated based on mathematical formulas that give different weightings to various institutional criteria.
Here is an example of the typical breakdown of criteria from one of the most famous rankings in the world, the QS World University Rankings:
| Evaluation Criterion | Weight in Final Score | What it means in practice |
| Academic Reputation | 40% | Academics’ views on research quality. |
| Citations per Faculty | 20% | The impact and relevance of scientific research. |
| Faculty/Student Ratio | 20% | Teaching closeness and class sizes. |
| Employer Reputation | 10% | How much your degree is valued in the job market. |
| International Faculty | 5% | Attracting global teaching talent. |
| International Students | 5% | Cultural diversity on campus. |
As you can see, a massive slice of the score (40%) comes from Academic Reputation, which is based on opinion surveys sent to thousands of professors and researchers worldwide. Another 20% is allocated to Citations per Faculty, which measures the number of scientific papers published by that university’s staff.
This means that more than half of a university’s score in a ranking depends on its volume of scientific research. A faculty might have brilliant professors publishing ground-breaking studies—securing an excellent position in the ranking—but undergraduate classes might be taught in massive lecture theatres with 300 students, where you will never get to speak directly to the lecturer.
Three Things to Keep in Mind When Analysing Rankings
To use these tables to your advantage, you should follow these three golden rules:
- Look for Subject Rankings: A university might be ranked number 300 globally but sit within the global Top 20 for a specific course like Civil Engineering or Hospitality Management. Always analyse the reputation of your specific department rather than just the institution’s overall name.
- Assess the Faculty-to-Student Ratio: If you value close, dynamic guidance, look at the score for the Faculty/Student Ratio. The higher this score, the more lecturers there are for each group of students, which translates into smaller classes and greater individual support.
- Pay Attention to Employer Reputation: This is one of the most valuable pieces of data for your future. It measures the opinions of global companies regarding how well-prepared a university’s graduates are. A good score here means the job market recognises and values your degree when you send out your CV.
The Ideal Ranking is the One That Suits Your Profile
The biggest mistake is choosing a university solely based on the prestige of its number in an official table. What is the use of studying at the 80th best university in the world if it is located in an isolated town where you cannot adapt, or if the cost of living completely exceeds your family’s budget?
Factors such as the local cost of living, the country’s culture, work placement opportunities included in the course, and your own learning style are far more decisive for your success than any statistical position on the internet.
At StudyWing, we teach students how to read between the lines of this data. We help you cross-reference the actual reputation of courses with your financial, geographical, and professional needs. Our goal is to find the perfect institution where you will build a successful career and enjoy the best experience of your life.
