About the Graduate School Guide

PhDs.org was originally funded by the Alfred P. Sloan Foundation, the Burroughs Wellcome Fund, the National Postdoctoral Association, and the Center for Science and the Media. Our goal is to provide the most accurate and recent data for every doctoral program in America. So far, the site has been a success. We've been mentioned for our custom rankings by the National Academy of Sciences and over the years helped thousands of students who used our profiles and rankings.

We understand some of the statistics and rankings reported from the NRC can be confusing. To help clarify how the rankings were created, we’ve explained the process in a set of articles. We recommend you read them in the order we set below, starting with the Frequently Asked Questions.
