Behind the Rankings: Criteria and Methodology

The Quacquarelli Symonds’s website explains the criteria that are used to assign ranks. The basic categories are only four: 

• Learning/teaching environment, 
• Research reputation 
• Research impact 
• Internationalisation 

The categories are further broken down into indicators: 

Academic Reputation: 

Academic reputation index carries the highest weightage in the scale. Asks the question ‘Which universities are performing world-class research? The question is not only about the quality of research, but also about the ability to communicate research and make an impact.

Citations per Faculty: 

This too is a major index. It shows the relative intensity and volume of research being done at an institution. QS takes into account the size of the institution. 

Faculty Student Ratio:

Faculty student ratio is important because the more academic staff resources (teaching, supervision, curriculum development, and pastoral support) available to students, the better the department. 

Employment Outcomes:

Obviously, this has to be ranked. What could be more important to a student than the chance of finding a job after graduation. It’s why students enrol into a university in the first place. This index shows two things: the institution’s ability to place their graduates, and the ability to turn out future leaders who will have an impact on their respective fields. This also reflects what employers think of the institution. 

International Faculty Ratio: 

A high ratio of international faculty vis a vis overall staff, indicates that the institution has research and teaching diversity and collaboration and is good enough to attract overseas staff.
