<p>When you look at the per-capita top ten undergrad schools producing future PhDs in all disciplines, five are LACs, so it’s a wash. LACs have the advantage of no TAs, small classes, and close personal mentorship; non-LACs have the advantage of top research facilities, famous professors and broad programs. Both systems work very well, and have their own strengths.</p>
<p>Per capita is important to a HS senior. All other things being equal (though they never are), her chances are better, e.g., at a school where 25 of 100 go on to later earn a PhD, rather than 50 of 1000.</p>
