For the fourth year in a row, Caltech is being rated the best research university in the world by the Times Higher Education magazine of Great Britain, according to a survey released Wednesday.
Three other California schools were in the journal's top dozen: Stanford, ranked fourth; UC Berkeley, eighth; and UCLA, 12th.
The Times Higher Education listing emphasizes research and research reputation more strongly than some other rankings of universities. Among its scoring categories are income from research, the amount of faculty research published in scholarly journals and the number of international students and faculty.
After the Pasadena campus, the rest of the magazine's top 10 in "World University Rankings" are Harvard, the University of Oxford, Stanford, the University of Cambridge, MIT, Princeton, UC Berkeley, with Yale and Imperial College of London tied at ninth.
Other California campuses in the top 100 were: UC Santa Barbara, 37; UC San Diego, 41; UC Davis, tied at 55 with Katholieke Universiteit Leuven of Belgium; USC, tied at 75 with the University of Basel in Switzerland; and UC Irvine, sharing 88 with Tufts.
Caltech issued a statement Wednesday attributing its success in the ranking to its faculty and researchers.
"At Caltech, our culture of curiosity, interdisciplinary collaboration, and intellectual freedom both inspires and depends upon an exceptional community of researchers, educators, and scholars," the statement said.
"Their focus on fundamental and applied research, and on crossing the boundaries between disciplines, results in new fields of inquiry and in transformational discoveries in science and technology. It is they who make Caltech what it is," the statement said.
