United States National Research Council rankings

The United States National Research Council conducts a survey and compiles a report on United States Research-Doctorate Programs approximately every 10 years, although the time elapsed between each new ranking has exceeded 10 years.

Data collection for the most recent report began in June 2006; it was released on September 28, 2010. These rankings did not provide exact ranks for any university or doctoral program; rather, a statistical range was given. This was because "the committee felt strongly that assigning to each program a single number and ranking them accordingly would be misleading, since there are significant uncertainties and variability in any ranking process."

Two series of rankings were offered:

The factors included in these computations included the number of publications per faculty member, citations per publication (except in computer science and the humanities), fraction of the faculty supported by grants and number of grants per faculty member, diversity of the faculty and students, student GRE scores, graduate student funding, number of Ph.D.s and completion percentage, time to degree, academic plans of graduating students, student work space, student health insurance, and student activities.

The rankings have both been praised and criticized by academics.

Physicist Peter Woit stated that historically the NRC rankings have been the "gold standard" for academic department ratings. The rankings were also called "the gold standard" by biomedical engineer John M. Tarbell and in news releases by Cornell University and the University of California. The Center for a Public Anthropology praised the National Research Council's 2010 rankings as "an impressive achievement" for its move away from reputational rankings and toward data-based rankings, but also noted that the lack of specific rankings reduced clarity even as it improved accuracy.William Colglazier and Jeremiah P. Ostriker defended the rankings in the Chronicle of Higher Education, responding to a critique by Stephen M. Stigler.
