Some questions to ponder while we all continue to wait for the new NRC rankings: Are the data that will be used in the rankings losing their analytical validity since they will be from the 2005-2006 academic year? Why wasn't the NRC able to produce its rankings more quickly, using more up-to-date information? How many faculty members have switched institutions and departments since the NRC first started collecting data in fall 2006? This is very important because faculty data are a key part of the NRC's analysis.
