Information | University Rankings

The focus of this system is on research activity, thereby enabling a uniform comparison between universities. This focus is based on the premise that good research results lead to good results in the other dimensions.

The positioning system is individualised for the top 100 universities, while from position 101 onwards positioning is grouped according to the categories defined by the ranking. Since 2003, ARWU has annually presented the world's top 2,000 ranked universities.

• Alumni (10%)number of students awarded the Nobel Prize or the Fields Medal,
• Prize (20%)number of employees awarded the Nobel Prize or the Fields Medal,
• HiCi (20%)Number of highly cited researchers in 21 fields, as defined by the ARWU service.,
• North & South (20%)number of scientific papers published in the scientific journals Science and Nature,
• Publication (20%)the number of academic papers registered in the Science Citation Index and the Social Science Citation Index and
• PCP (10%)"productivity per researcher at the institution", i.e. the sum of all the above indicators, divided by the number of the institution's full-time academic staff.

• performance in the Academic Ranking of World Universities by main scientific research fields, ARWU-FIELD:

• Social sciences

• performance in the Academic Ranking of World Universities by scientific research fields, ARWU-SUBJECT:

Since 2012, CWUR has been publishing an academic world university ranking that assesses the quality of education, student employment, research output and citations, without relying on surveys or data provided by the universities. Initially, the CWUR ranking presented the top 1,000 of over 18,000 universities analysed worldwide. Since 2019, the published ranking results have been expanded to include the top 2,000 universities.

1. Quality of education, measured by the number of a university's alumni who have won important international awards and medals relative to the university's size (15%).
2. Employment of alumni, measured by the number of alumni of a university who held managerial positions in the world's leading companies relative to the university's size (15%).
3. Quality of teaching staff, measured by the number of academics who have received significant international awards and medals (15%).
4. Research results, measured by the total number of scientific research papers (15%)
5. Quality publications, measured by the number of scientific research papers appearing in top-tier journals (15%)
6. Influence, measured by the number of scientific research papers appearing in high-impact journals (15%)
7. Quotes, measured by the number of highly cited research papers (10%)

In addition to the QS World University Rankings, this service also publishes and Specific rankings, according to the criteria introduced:

• QS Regional Rankings – European Regional Ranking, LATAM Ranking, BRICS Ranking, Asian Ranking,
• Quality Street World University Rankings – by fields of scientific research, classified into 5 groups (Arts and Humanities; Engineering and Technology, Natural Sciences, Bio-sciences and Medicine, and Social Sciences) and 48 research areas.
• Quality Street Top Under 50 50 World University Rankings – ranks the world's best universities that are under 50 years old, to allow some of the world's best young universities to stand out against those with much longer histories.

In addition to the aforementioned rankings, the QS World University Rankings service publishes a system for evaluating the performance of universities in various fields, called QS Stars University Ratings, whereby instead of comparing institutions with one another, they are assessed on their performance against the established standard.  This system for evaluating university performance functions as a review of the universities' strengths and weaknesses, through an analysis of the data provided across a dozen indicators.The audit awards stars both by category and on a global level, without imposing a limit on the number of universities that can achieve the highest score or a relative ranking among them.

1. Academic reputation (30%) – based on academic research into the quality of teaching and research at world universities.
2. Employer's reputation (15%) – based on research that asks employers to identify the institutions producing the most competent, innovative and efficient graduates. The QS Employer Survey is one of the largest of its kind in the world.
3. Teacher-pupil ratio (20%) – an indicator that assesses the extent to which institutions can provide students with meaningful access to professors and tutors.
4. Ratio of citations per research staff member (20%) – an indicator that measures the quality of institutional research by calculating the total number of citations for all papers produced by an institution over a five-year period, divided by the number of faculty members at that institution. To account for the fact that different research fields have very different publication cultures, citations are normalised, thereby ensuring an objective assessment of the impact of the research in various fields undertaken by an institution. This university ranking service, as a source for analysing scientific research papers and citations, uses Elsevier's Scopus database, with self-citations excluded beforehand, analysing publications from the last five years.
5. Ratio of international teachers to international students (5%) – an indicator of the advantages of universities that attract teachers and students from all over the world, which suggests they have a strong international reputation.
6. International research network (5%) – an indicator that reflects the ability of institutions to build diversified international research networks.
7. Employability outcome (5%) – an indicator that reflects the ability of institutions to provide a high level of employability for their graduates.
8. Sustainability (5%) – an indicator that indicates which institutions demonstrate a commitment to a more sustainable existence and sustainable development.

At present, several rankings are being published:

On a global level:

• The World University Rankings
• The World Reputation Rankings
• The University Impact Rankings
• THE Young University Rankings

For teaching:

• Wall Street Journal / THE College Rankings
• THE Europe Teaching Rankings

At regional level:

• The Emerging Economies University Rankings
• The Latin America University Rankings

By fields of knowledge:

• The Global Subject Rankings

• Teaching (30%)
• Research (30%)
• Quotes (30%)
• International perspective (7,5%)
• Industry revenue and knowledge transfer ((2,5%)

For this ranking service, the indicators They are divided into three groups intended to reflect the scientific, economic and social characteristics of the institutions. SCImagoIR provides global statistical data on the institutions' scientific publications and other outputs, thereby enabling comparisons to be made between institutions of different sizes.

The methodology is based on the following three global indicators, which represent groups of sub-indicators (each assigned a different weight), with the final values normalised on a scale from 0 to 100.

• Research indicators (50%, data extracted from Scopus)
• Innovation indicators (30%)
• Social impact indicators (20%)

The methodology has evolved significantly over the past decade, so that the results from the different editions are not directly comparable.

The methodology is based on the following indicators with appropriate weighting factors:

• Presence (5%) – number of pages on the institution's main web domain.
• Influence / Visibility (50%) – number of external networks that have links to the institutions' websites.
• Openness/Transparency (10%) – number of citations by the main authors, with the source being Google Scholar Citations.
• Excellence (35) – number of academic articles published in high-impact international journals, drawn from the top 101 most-cited authors in their respective scientific disciplines. The source of the indicator is Scimago.
