The Top 400 World Universities

London Times & Thomson Reuters:

The Times Higher Education World University Rankings were developed in concert with our rankings data provider, Thomson Reuters, with expert input from more than 50 leading figures in the sector from 15 countries across every continent. We believe we have created the gold standard in international university performance comparisons.
Our rankings of the top universities across the globe employ 13 separate performance indicators designed to capture the full range of university activities, from teaching to research to knowledge transfer. These 13 elements are brought together into five headline categories, which are:
Teaching — the learning environment (worth 30 per cent of the overall ranking score)
Research — volume, income and reputation (worth 30 per cent)
Citations — research influence (worth 30 per cent)
Industry income — innovation (worth 2.5 per cent)
International outlook — staff, students and research (worth 7.5 per cent).

The University of Wisconsin-Madison ranks 27th.
