<p>The Selectivity list from US News is as follows:</p>
<ol>
<li>Harvard</li>
<li>MIT
Yale</li>
<li>Caltech
Princeton</li>
<li>UPenn
WashU</li>
<li>Brown
Stanford</li>
<li>Columbia
Dartmouth
Duke
Rice</li>
</ol>
<p>Clearly this ■■■■■■■■■■■ list is incomplete if not completely wrong. If you were to base selectivity only on admissions rates (the US News ranking takes into account other things) than Caltech would still be on that list (21% acceptance rate in 04)</p>
