This was the first big ranking. It started in 2003. The order is determined by a number of indicators for good research. For example, consider the number of Nobel Prizes and Fields Medals won by staff members and alumni, the number of citations and the number of articles published in ‘Nature' and ‘Science'.
Education, impact of citations and research play important roles in this ranking. On top of that, Times Higher Education also looks at international perspectives and research income from corporations.
This ranking is based on research achievements. Among other things, CWTS includes the share in the 10 % most cited publications.
The NTU fully focuses on scientific output: the number of scientific publications, the number of citations and the number of 'highly cited papers' and publications in 'high impact journals'.
The compilers of the QS Ranking look at scores for research quality (citations and peer review), the staff-to-students ratio, the number of international scientific staff members and students, and the reputations of universities among employers.
This list is compiled based on research reputation, primarily of publications and the impact they have.
Studiekeuze123 holds a survey among several hundreds of thousands of students at applied-science universities and universities. Among other things, they test the content of the education programmes, the quality of the lecturers, the education facilities and how challenging education is.
The Nationale studentenenquête asks students to 'Indicate how satisfied you are with your education in general.' This forms the basis of Elsevier's ranking. This opinion magazine takes the average of the answers provided by full-time students. Of the number of degree programmes rated in this way, Elsevier observes how many of them were rated more positive than the average.
The Keuzegids (Choice Guide) converts results of the Nationale Studenten Enquête into a mark and takes the average from among several degree programmes. The factors they measure are education, communication, art and culture, law and governance, economics, social, health, Earth and environment, exact sciences and ICT, engineering and interdisciplinarity.
