The University of California, San Diego was ranked as the 15th best university in the world by the 2017 Academic Ranking of World Universities (ARWU).
The school was also recognized Friday as the 13th best university overall in the U.S. and the world' third best public college.
"UC San Diego is honored to be recognized by the Academic Ranking of World Universities for our commitment to academic excellence," said Chancellor Pradeep K. Khosla. "With a campus culture that embraces risk-taking and collaboration, UC San Diego leverages boundary-breaking research and world-class education to benefit humankind and our planet."
The ranking was based on six objective indicators, according to the ARWU--the number of alumni and faculty winning Nobel Prizes and Fields Medals, the number of highly cited researchers, the number of articles published in journals of Nature and Science, the number of articles indexed in Science Citation Index and per capita performance.
This is not the first time UC San Diego has been ranked among some of the top universities in the world.
Times Higher Education World Reputation Rankings 2017 placed the university as 29th.
The year before, the U.S. News & World Report's 2016 Best College guidebook named UC San Diego as the ninth best public university in the nation.
