Sept. 28, 2010 — The National Research Council today released its assessment of U.S. doctoral programs, which includes data on over 5,000 programs in 62 fields at 212 universities nationwide.  The assessment is designed to help universities evaluate and improve the quality of their programs and to provide prospective students with information on the nation's doctoral programs. (See Full Report)

"This report and its large collection of quantitative data will become in our view an important and transparent instrument for strengthening doctoral education in the United States," said the presidents of the National Academy of Sciences, National Academy of Engineering, and Institute of Medicine in a foreword to the assessment.  NAS President Ralph Cicerone, NAE President Charles Vest, and IOM president Harvey Fineberg serve on the governing board for the National Research Council. "All those interested in graduate education can learn much from studying the data, comparing programs, and drawing lessons for how programs can be improved," they added.

The assessment includes a report explaining the study committee's methodology and general findings about doctoral education, along with an Excel spreadsheet containing data on characteristics for each program.  The spreadsheet also includes five sets of illustrative rankings that show how the data can be used to compare programs based on the importance of particular program characteristics to various users -- in this case, to faculty at participating universities.  The rankings are not endorsed by the Research Council as an authoritative conclusion about the relative quality of doctoral programs, but illustrate the kinds of valuations that can be generated from the data. 

A spreadsheet containing the data and illustrative rankings for all programs can be found at, along with the full text of the report and a detailed guide to the study's methodology.  

The assessment provides data on the following characteristics for participating Ph.D. programs.  The data were collected from institutions for academic year 2005-2006 through questionnaires distributed to faculty, administrators, and students, as well as from public sources.  The data set will allow universities to update key information on a regular basis.

-- Median time to degree
-- Percent students with academic plans           
-- Student work space                               
-- Student health insurance                                 
-- Number of student activities offered             

Illustrative Rankings Based on Data, Faculty Values

The data presented in the assessment also were incorporated into illustrative rankings of programs in each field.  While the illustrative rankings should not be interpreted as definitive conclusions about the relative quality of doctoral programs, they provide important insights on how programs can be ranked according to different criteria and on the characteristics faculty value most. 

Two different methods were used to determine how much importance or "weight" faculty in each field attach to 20 different program characteristics (19 in the case of computer science and the humanities fields).  These weights were then applied to data on the characteristics for all of the programs in the field, resulting in two sets of illustrative rankings for each program.  The illustrative rankings are given as ranges of numbers -- rather than a strict "1,2,3"-style ordering of programs -- to reflect some of the uncertainties inherent in any effort to rank programs by quality. 

In addition to these two "overall" ranges of rankings, illustrative rankings are included for each program for three separate aspects of graduate education: the research activity of program faculty, student support and outcomes, and diversity of the academic environment.  

The report urges prospective students, administrators, faculty members, and others to consider which characteristics are most important to them and to compare programs accordingly.  Tutorials that demonstrate how to use the spreadsheets to compare programs can be found at  In addition,, an independent web site not affiliated with the National Research Council, has incorporated data from the assessment into its Graduate School Guide.  Users of's Guide can assign weights to the program characteristics measured by NRC and others, and rank graduate programs according to their own priorities.

Trends in U.S. Doctoral Education

The study committee also assessed the data to discern trends in U.S. doctoral education since the National Research Council's last assessment was released in 1995, based on data collected for 1993.  The following comparisons are limited to programs that participated in both studies.

The report also includes general findings on doctoral education in the U.S. -- for example, on the amount of time it takes students to finish their degrees.  Over 50 percent of students in agricultural science and engineering complete their degrees in six years or less, while only 37 percent of those in the social sciences do -- the same percentage of humanities students who complete by eight years. 

The National Academy of Sciences, National Academy of Engineering, Institute of Medicine, and National Research Council make up the National Academies.  They are independent, nonprofit institutions that provide science, technology, and health policy advice under an 1863 congressional charter.  A committee roster follows.
