The 2015 Times Higher Education World University Rankings: California Institute Of Technology Emerges As The World’s Top Research University For The Fifth Consecutive Year

The California Institute of Technology has been ranked by the Times Higher Education in London as the world's top research university for its fifth straight year, reported Los Angeles Times on Wednesday.

The Times Higher Education ranking gives more impact on research reputation as compared to other university rankings. Some of its rating categories include the amount of scholarly publications, income generated from research and how international the students and faculties are.

Washington Post noted on Wednesday that The Times Higher Education website says, "The Times Higher Education World University Rankings 2014-2015 list the best global universities and are the only international university performance tables to judge world class universities across all of their core missions - teaching, research, knowledge transfer and international outlook."

According to the president of California Institute of Technology, Thomas F. Rosenbaum, in his statement released on Wednesday, the ranking highlighted his university's strength in "venturing into unexplored realms, defining new fields in science and engineering, and pushing interdisciplinary boundaries in the service of discovery,"

 "It also points to the competitive nature of higher education, where maintaining a culture of intellectual risk taking is essential to attract the most creative and original scholars, scholars who have choices among many exceptional academic institutions across the world," added Rosenbaum.

Contenders for the World University Rankings are required to teach undergraduates and produce at least 200 research articles annually. They are then judged by the Times Higher Education through the following criteria: teaching, research, citations, international outlook and industry income, noted The Street on Friday.

The editor of the Times Higher Education World University Rankings, Phil Baty, noted that the U.S. prevailed the rankings, with 63 institutions among the top 200.

"The U.S. will have to raise its game to ensure its dominance does not erode," said Baty.
