With hundreds of universities to choose from globally, rankings can offer a quick snapshot of academic excellence and reputation. But how are these rankings created, and how much should they influence your decision?

We will break down the most trusted global ranking systems, explain what they measure, and help you understand how to use (and not misuse) them when planning your academic future. 

Major university ranking systems

Not all rankings are created equal. Here are the most influential global university ranking systems: 

  • QS World University Rankings: Known for prioritising academic reputation, employer reputation, and international student/faculty ratios. 

  • Times Higher Education (THE): Focuses on teaching, research, citations, international outlook, and industry income. 

  • Academic Ranking of World Universities (ARWU/Shanghai Rankings): Research-heavy, giving weight to publications, Nobel Prizes, and prestigious academic performance. 

  • U.S. News & World Report (Best Global Universities): Emphasises research reputation and output. 

Each ranking has its own formula, so the same university may rank differently across them.

Factors considered in World University Rankings

Most ranking bodies use a mix of the following indicators: 

  • Academic reputation (based on surveys of academics worldwide) 

  • Employer reputation (surveyed opinions of employers about graduate quality) 

  • Faculty/student ratio 

  • International student and staff numbers 

  • Research output (publications, citations) 

  • Teaching environment 

  • Industry income and innovation impact 

  • Awards and recognitions (e.g., Nobel Prizes) 

Criticism and limitations of World University Rankings

It’s important not to rely solely on rankings. Here’s why: 

  • Overemphasis on research: Teaching quality often takes a backseat. 

  • Limited student-focused metrics: Many don’t measure student satisfaction, support services, or campus life. 

  • Lack of context: A high rank doesn’t always mean a great fit for your goals or background.
