Board on Higher Education & Workforce:

A revised Excel Data Table for the NRC Data-Based Assessment of Research-Doctorate Programs in the United States is now available. A summary of changes for each program can be found here. Those who wish to compare the September 28, 2010 version of the Data Table to the revised rankings, may find the old rankings here.
The revisions are in response to communications and queries received by the NRC since the first Data Table was released on September 28, 2010. At that time, the NRC agreed to follow up on queries about the data and these were received from approximately 450 doctoral programs from 34 institutions. Ten of these institutions had queries for 10 or more of their programs.
The most common questions centered around faculty lists and related characteristics: publications per allocated faculty member, citations per publication, the allocation of faculty, and the measure of interdisciplinarity that used this measure. The NRC was not able to permit changes in faculty lists from what universities had originally submitted. That would have required enormous expense to completely redo the study with the 2005/6 data.
