QS World University Rankings Explained: Everything International Students Need to Know

Quacquarelli Symonds, also known as QS, is a  UK-based higher education analytics company publishing global rankings of higher education institutions annually. It was launched in 2004, and since then it has become one of the most famous and trustworthy ranking systems worldwide.

Numerous universities get evaluated every year worldwide in consideration of factors such as academic reputation, research quality, employability, international diversity, and sustainability. With the help of this ranking, students get to compare institutions not only based on where they are situated but also where the university is standing globally.

Lately, not only students or universities but also employers and governments trust  QS rankings as a crucial factor to examine any institution’s performance or reputation.

QS evaluates universities using nine key performance indicators, each contributing a specific percentage to the overall score.

1. Academic Reputation (30%)

In QS methodology, academic reputation is one of the most influential factors.

QS survey is one of the world’s largest academic surveys, interviewing professors, researchers, and academics to shortlist top-notch universities offering best-quality teaching and research according to them.

A university that consistently earns recognition from global academics receives a higher score in this category.

2. Citations per Faculty (20%)

Research excellence is another major component of the ranking.

QS measures the impact of a university’s research by analyzing how frequently its published research papers are cited by other researchers. Instead of simply counting the number of publications, this indicator evaluates the influence and quality of the research produced.

Universities that contribute groundbreaking or widely referenced research generally perform well in this category.

3. Employer Reputation (15%)

A university’s reputation among employers is equally important.

QS surveys employers worldwide to determine which universities produce graduates with the knowledge, skills, and workplace readiness that organizations value most.

This indicator helps students understand how well graduates from a particular university are regarded in the global job market.

4. Faculty-to-Student Ratio (10%)

This indicator assesses the number of academic staff relative to the student population.

A higher faculty-to-student ratio often indicates:

• Smaller class sizes
• Better interaction with professors
• More personalized academic support
• Enhanced learning experiences

Although it does not directly measure teaching quality, it provides insight into the resources available to students.

5. International Faculty Ratio (5%)

Universities with faculty members from different countries create a more diverse academic environment.

This indicator measures the proportion of international faculty employed by an institution, reflecting its global appeal and ability to attract academic talent from around the world.

6. International Student Ratio (5%)

A diverse student community enriches the learning experience.

QS evaluates the percentage of international students enrolled at each university, recognizing institutions that successfully attract learners from different cultures and backgrounds.

For international students, this often translates into greater networking opportunities and a more inclusive campus environment.

7. International Research Network (5%)

Modern research increasingly depends on global collaboration.

This indicator measures how effectively universities work with international institutions through collaborative research projects and co-authored publications, highlighting their contribution to the global academic community.

8. Employment Outcomes (5%)

Beyond employer perception, QS also evaluates how effectively universities prepare students for successful careers.

This indicator considers graduate employability, alumni achievements, and the institution’s ability to produce professionals who make meaningful contributions across industries and society.

9. Sustainability (5%)

Recognizing the growing importance of environmental and social responsibility, QS introduced sustainability as a ranking indicator.

Universities are assessed on factors such as environmental initiatives, social impact, governance, and sustainability-related research, encouraging institutions to contribute positively to global challenges.
