Put to the test: Website ranks the best ag schools in the worldMary Delany, interim dean of the College of Agricultural and Environmental Sciences at UC Davis, said the university is thrilled to receive the number one ranking.

"At the institutional level, this ranking signifies rich teaching and research programs that developed and were built during our more than 100 years of service," she said. "And at the personal level, it reflects the devotion of more than 300 faculty members who are passionate about their fundamental, translational and applied research, and thoroughly devoted to training the next generation of scientists and agriculturalists."

QS World University Rankings have provided university rankings for three years, but this is the first year ranking schools in the agriculture and forestry division. The firm evaluated 2,858 universities and ranked 678 of those institutions in 30 subject areas.

The firm uses six indicators to rank each university: academic reputation, employer reputation, citations per faculty, faculty-student ratio, proportion of international students and proportion of international faculty -- to form an international ranking of universities.

QS World University Rankings are prepared by Quacquarelli Symonds (QS), a British firm that previously was the data provider for the annual Times Higher Education rankings. The firm is widely considered to be one of the most influential international university rankings providers.
