For the second year in a row, Caltech has been ranked the best university in the world by the British magazine Times Higher Education.
Harvard dominated the top spot on the magazine's World University Rankings from 2004 to 2010. But Caltech raised to the top in 2011 and held onto its title again this year.
The magazine ranks universities based on a number of factors, including research, teaching, citations and international outlook. The Pasadena institute also received high marks in subjects such as engineering, technology and physical sciences.
