<p>I think your comments have some merit. No method is going to be perfect and I can’t speak to how they manage their way through the issues you raise. That doesn’t mean that they don’t do it very professionally and systematically, but you’re right that we don’t know. </p>
<p>One way that I check this is to read some of their materials on a dozen or so schools that I have fairly good knowledge of. As I posted earlier, I’ve been impressed by how much they get right. Is 100% accurate? No, but it’s pretty good and certainly a heckuva lot more relevant to most prospective students than the abominations of the PA scoring.</p>
