<p>UCB, throwing a word like "silly" in this discussion is my way of keeping a modicum of humor in this discussion.</p>
<p>The reality is that we all know that the PA will not change much from year to year, and that its objective has been well documented by Morse of USNews. I also think we all know that it is hardly what people pretend it to be. There are sufficient accounts of its shortcomings --mostly at the level of the interpretation on how to fill the survey and integrity/knowledge of the surveyees. In turn, we are trying to reengineer or deconstruct a measurement that is utterly resistant to logic and hard data when individual schools are placed under the microscope. </p>
<p>IMHO, there are no good ways to explain the differences in PA between Cal, and UCLA, just as a VALID explanation for the PA of Smith versus Harvey Mudd is impossible. </p>
<p>In the end, nobody denies that all the schools discussed here are amazing institutions. All our debates merely reflect the fact that there are NO mechanism that can --or should-- measure the quality of education. Any of us can focus on minute items and defeat the arguments of others. </p>
<p>Fwiw, I'll repeat that I believe that the PA should be an important metric. Actually, I believe it should be expanded and broken down in sub-categories, and I believe that one metric should underscore the importance of a world-known faculty at the graduate level. I do think, however, that USNews does muddy the waters by mixing the PA with the remaining data. For this reason, I would love to see two sets of rankings on separate pages. </p>
<p>This way, all of us would be happy as we focus on what is important in our individual eyes.</p>
