The peer assessment is a subjective ranking but it is far from random; it is quite valid. It IS scientific in the sense that PA is predictable from hard data. The judgements of the raters reflect real differences among schools. Reputations are earned and deserved, and the PA raters judgements reflect that. If PA were random it wouldn't be so closely related to other, objective factors.</p>

The link I gave you was to illustrate that the R-squared for predicting PA can be much higher than the .71 you quoted. I identified a model with a 94% R-square for predicting PA based on US News data alone. Trust me. If I get a chance, I will post it.</p>

Emory, Rice, Vanderbilt, Georgetown, Tufts, Wake Forest, William and Mary have closed the SAT gap on the Ivies by about 30 points in the last 40 years. It's surprising that they have not closed the gap more when you consider that the college-going population has more than doubled in the same time period. But, maybe the increase in college-going population has been more confined to lower-achieving students.</p>
<p>All these claims that the PA reflects graduate program quality are simply without basis. About 6% of the PA can be explained by NRC rankings, the rest can be explained by the data in US News. PA SHOULD be related a little to grad school quality because undergrads benefit from faculty scholarship and research opportunities.</p>
