University rankings

Shanghai-ranking (ARWU) is the oldest and most well known university ranking published by Shanghai Jiao Tong University. The comparison, which has appeared since 2003, emphasizes the Nobel and Fields Prizes, articles published in the journals Nature and Science, and references to research and researchers in its assessment.

The indicators and weights used to calculate the ranking:

• Alumni of an institution winning Nobel Prizes and Fields Medals 10 %
• Staff of an institution winning Nobel Prizes and Fields Medals 20 %    
• Articles published in Nature- ja Science 20 %
• Research citations 20 %
• Highly cited researchers 20 %
• All pre­vi­ous ele­ments in re­la­tion to the num­ber of aca­demic staff 10 %.

THE (Times Higher Education) ranks universities on the basis of teaching, research, research references, internationalisation and funding from companies. Teaching and research are evaluated in addition to numerical values through surveys.

The indicators and weights used to calculate the ranking:

• Teaching 30 %
  (Teaching reputation, ratio of number of doctorates awarded to number of academic staff, ratio of number of staff to number of students, ratio of doctorates to bachelor's degrees, university income relative to number of academic staff)
• Research 30 %
  (Research reputation, publications in relation to academic staff, research funding in relation to academic staff)
• Research cita­tions 30 %
• Internationalization 7,5 %
  (Share of foreign students, share of foreign academic staff, international co-publications)
• Research funding received from companies in relation to academic staff 2,5 %

QS ranking emphasizes the reputation of the university, the number of citations, the ratio of the number of teachers to students, and the proportion of international staff and international students. Reputation surveys for QS comparison are based on surveys for researchers and employers and have a high weight in comparison.

The indicators and weights used to calculate the ranking:

• University's reputation in surveys for researchers at other universities 40 %
• University's reputation in surveys for employers 10 %
• Number of citations relative to academic staff 20 %
• Ra­tio of stu­dents to teach­ers 20 %
• Ratio of international staff 5 %
• Ratio of international students 5 %

CWTS Leiden ranking lists universities based on publications. Leiden uses a partial method of calculation in the assessment, meaning the weighting of the publication is lower if there are authors from several universities. The default comparison is based on the spread number of publications, but better comparing the quality of publications takes into account those publications that rank in the most cited 10% in their field.
