Duke is tied with Harvard University for No. 1 nationwide in terms of graduate outcomes in the latest set of Wall Street Journal/Times Higher Education rankings. 

The rankings also placed Duke at No. 5 overall, higher than Yale University, Princeton University and the University of Pennsylvania. Ahead of Duke were Harvard University, Columbia University, Stanford University and the Massachusetts Institute of Technology. 

The rankings are based on 15 individual performance indicators, some of which are based on responses from 200,000 current students, according to the Times website. The indicators are categorized into four sections: resources, engagement, outcomes and environment.

For graduate outcomes, the rankings take into account graduation rates, the salaries that graduates own and the debt they carry. 

Earlier this year, the U.S. News and World Report dropped Duke down to No. 9 from its No. 8 spot last year.
