University Rankings are a major factor for many students when selecting which university to attend. They are generally perceived as an important indication of prestige of the university and quality of their research and education.
There are many university rankings published annually. Some rankings evaluate universities within a single country, while others assess institutions worldwide. In the United States, U.S. News and World Report, The Wall Street Journal and Forbes Magazine are among the more recognized rankings. In Korea the Korean Council for University Education evaluates universities.
Times Higher Education (THE), QS World University Rankings®, U.S. News & World Report and Academic Ranking of World Universities (ARWU) also known as Shanghai rankings are among the more recognized global university rankings.
THE World University Rankings 2023 included 1,799 universities across 104 countries. It used 18 performance indicators (PIs) to determine the rankings. Research environment and research quality make up 59% of the grade with teaching 29.5%. International collaboration and international outlook are also considered (10%)
QS world university rankings are prepared by the British Company Quacquarelli Symonds (QS). The 20th edition of the rankings featured 1,500 universities across 104 locations. The highest weighted PI in QS ranking is the Academic Reputation of the University (30%) followed by faculty citations (20%). Since 2023, QS has included Sustainability, Employment Outcomes and International Research Network (each 5%) in their methodology. Teaching related measures (faculty student ratio) only determines 10% of the grades.
The 2022-2023 U.S. News & World Report Best Global Universities Rankings included 2000 universities from 95 countries. The rankings are based on thirteen PIs, all of which are research oriented with no teaching related indicators involved.
ARWU published by Shanghai Ranking Consultancy, considers every university that has any Nobel Laureates, Fields Medalists, Highly Cited Researchers, or papers published in Nature or Science. In addition, universities with a significant amount of papers indexed by Science Citation Index-Expanded (SCIE) and Social Science Citation Index (SSCI) are also included. In 2022 a total of more than 2500 universities were ranked, and the best 1000 were published.
ARWU uses four general indicators consisting of quality of education (10%), quality of faculty (40%), research output (40%) and per Capita Performance (10%). Quality of education and faculty are determined by such measures as the number of alumni and faculty receiving Nobel Prizes, Field Medals and highly cited research.
As it can be seen, these rankings are heavily focused on research and reputation of the universities. THE is probably a more balanced ranking system which includes teaching among its PIs.
University rankings have been criticized by many. One of the main criticisms has been that rankings reduces the universities’ performances to a set of numbers alone which can not convey the broader experience of education. Furthermore, these rankings pay minimal attention to the real-world undergraduate experience. Factors that can make a huge difference to a positive education.
As a result, some universities have been accused of “fudging” the data or “playing the numbers game” to improve their rankings without any consideration for the quality of their education. As an example, a number of Law Schools started to put more emphasis on LSAT scores after U.S. News gave more weight to the average LSAT scores of entering students. This came at the price of all other measures that could indicate the success of students.
Another problem with university rankings is the focus on perceived reputation. The QS and Shanghai rankings have been criticized for their overemphasis on these factors. Would hiring more Nobel Prize laureates on faculty really improve quality of education, particularly undergraduate education, where many of them may not even teach?
As a result of these controversies some universities have recently dropped out of rankings such as U.S. News. Withdraws form U.S. News rankings is most significant among Law schools and Medical Schools where almost all of the major universities such as Harvard, Columbia, John Hopkins, etc. Have recently dropped out. Among undergraduate program rankings, Colombia is the most recognized school that will no longer participate.
The general recommendation of many educators to students is that they should not consider rankings as the only (and even most significant) criterion for selecting schools. They should rather evaluate which university and program fits their profile and needs best and allows them to achieve their full potential.
