World University Ranking — Indicators and Weights for ARWU
As of August 2016

CriteriaIndicatorCodeDefinitionWeight
Quality of Education Alumni of an institution winning Nobel Prizes and Fields MedalsAlumni The total number of the alumni of an institution winning Nobel Prizes and Fields Medals. Alumni are defined as those who obtain bachelor, Master's or doctoral degrees from the institution. Different weights are set according to the periods of obtaining degrees. The weight is 100% for alumni obtaining degrees in 2001-2010, 90% for alumni obtaining degrees in 1991-2000, 80% for alumni obtaining degrees in 1981-1990, and so on, and finally 10% for alumni obtaining degrees in 1911-1920. If a person obtains more than one degrees from an institution, the institution is considered once only.10%
Quality of FacultyStaff of an institution winning Nobel Prizes and Fields MedalsAward The total number of the staff of an institution winning Nobel Prizes in Physics, Chemistry, Medicine and Economics and Fields Medal in Mathematics. Staff is defined as those who work at an institution at the time of winning the prize. Different weights are set according to the periods of winning the prizes. The weight is 100% for winners after 2011, 90% for winners in 2001-2010, 80% for winners in 1991-2000, 70% for winners in 1981-1990, and so on, and finally 10% for winners in 1921-1930. If a winner is affiliated with more than one institution, each institution is assigned the reciprocal of the number of institutions. For Nobel prizes, if a prize is shared by more than one person, weights are set for winners according to their proportion of the prize.20%
Highly cited researchers in 21 broad subject categoriesHiCi The number of Highly Cited Researchers in 21 subject categories. These individuals are the most cited within each category. If a Highly Cited Researcher has two or more affiliations, he/she was asked to estimate his/her weights (or number of weeks) for each affiliation. More than 2/3 of those multi-affiliated Highly Cited Researchers provided such estimations and their affiliations receive the weights accordingly. For those who did not answer, their first affiliation is given a weight of 84% (average weight of the first affiliations for those who replied) and the rest affiliations share the remaining 16% equally.20%
Research Output Papers published in Nature and Science*N&S ¹The number of papers published in Nature and Science between 2007 and 2011. To distinguish the order of author affiliation, a weight of 100% is assigned for corresponding author affiliation, 50% for first author affiliation (second author affiliation if the first author affiliation is the same as corresponding author affiliation), 25% for the next author affiliation, and 10% for other author affiliations. Only publications of 'Article' and 'Proceedings Paper' types are considered.20%
Papers indexed in Science Citation Index-expanded and Social Science Citation IndexPUBTotal number of papers indexed in Science Citation Index-Expanded and Social Science Citation Index in 2011. Only publications of 'Article' and 'Proceedings Paper' types are considered. When calculating the total number of papers of an institution, a special weight of two was introduced for papers indexed in Social Science Citation Index.20%
Per Capita Performance Per capita academic performance of an institutionPCP The weighted scores of the above five indicators divided by the number of full-time equivalent academic staff. If the number of academic staff for institutions of a country cannot be obtained, the weighted scores of the above five indicators is used. For ARWU 2012, the numbers of full-time equivalent academic staff are obtained for institutions in Australia, Austria, Belgium, Canada, China, Czech, France, Italy, Japan, Netherlands, New Zealand, Norway, Saudi Arabia, Slovenia, South Korea, Spain, Sweden, Switzerland, UK, USA etc.10%

CriteriaIndicatorDefinitionWeight ²
Research productivityPUBNumber of papers authored by an institution and indexed in Scopus in a specific subject area for the latest five calendar years. The publication types include articles, reviews as well as conference papers.100
High quality research outcomesTOP25Number of world top 25% most cited papers an institution has for the latest five calendar years.100
High quality research outcomesTOP1Number of world top 1% most cited papers an institution has for the latest five calendar years.100
 The institution's research quality as compared with the world average.FWCIHow the number of citations received by an institution's publications compares with the average number of citations received by all other similar publications in each engineering subject the Scopus database.200
International collaborationICCaptures the extent to which an institution's publications have international co-authorship. The data is collected for the latest five calendar years.100
Academic-corporate collaborationCCPercentage of an institution's publication with academic and corporate or industrial co-authors. The data is collected for the latest five calendar years. 200
Number of researchers with globally academic influencesMCRThe top 150-300 researchers in each subject with the highest  number of citations received.100
Academic achievement and recognitionAWARDNumber of the staff of an institution wining a significant award in an engineering subject. Different weights are set according to the periods of winning the prizes. The weight is 100% for winners after 2011.100
¹ Seven subjects in Engineering area are ranked: Chemical Engineering, Energy Science & Engineering, Civil Engineering, Electrical & Electronic Engineering, Mechanical Engineering, Environmental Science & Engineering, and Materials Science & Engineering.
² For each indicator, institutions are calculated as a percentage of the top scored institution and then multiplied by the allocated weight. A final score is arrived by adding scores for all indicators and the final score is ranked in descending order.
