When critics question the validity of the calculations U.S. News & World Report uses to rank colleges, one answer the editors of the magazine have given is to note that it publishes not only the total rank, but also data on how colleges perform in the various categories that go into the rankings. So a prospective student who cares more about faculty resources or competitiveness or any other factor can see how colleges do there, and judge accordingly.
But if the factor that would-be students and their families care about is a percentage of full-time faculty, you can’t count on the numbers about research universities to be correct. The two universities with the top scores in this category (both claiming 100 percent full-time faculty) have both acknowledged to Inside Higher Ed that they do not include adjunct faculty members in their calculations. U.S. News maintains that colleges do count adjuncts (or are told to) so that figure gives a true sense of the percentage of faculty members who are full time. But the two with 100 percent claims are not alone in boosting their numbers by leaving adjuncts out.
Some colleges that do so say that they read the instructions from U.S. News that way, and others say the magazine is itself inconsistent, in effect inviting them to do so. Others just leave the adjuncts out and don’t indicate that unless asked.
