<p>I would think that many students who want to study astrophysics in top undergraduate programs would seriously consider going on to doctoral programs in related fields. To these students, it might be important to observe which college departments seem to do the best job of attracting students, then motivating and preparing them to complete PhDs in those fields.</p>
<p>According to National Science Foundation data available on the webcaspar.com site, these are the 25 top colleges for PhD production in physics (based on the percentage of alumni earning doctorates in physics between 2007-2011):</p>
<p>California Institute of Technology
Harvey Mudd College
Massachusetts Institute of Technology
Swarthmore College
Reed College
Bryn Mawr College
Harvard University
Lawrence University
Williams College
University of Chicago
Haverford College
Princeton University
Carleton College
Stanford University
Rice University
Cornell University
Grinnell College
Rensselear
Vassar College
University of California-Berkeley
Colorado College
Johns Hopkins University
Columbia University in the City of New York
Oberlin College
Brown University</p>
<p>(Compare to the “physical science” list on this page: <a href=“Doctoral Degree Productivity - Institutional Research - Reed College”>http://www.reed.edu/ir/phd.html</a>)</p>
<p>My list is based on alumni PhDs earned in physics during 2007,2008,2009,2010, and 2011.<br>
It does not include PhDs earned in astronomy.
The ranking above is based on the percentage of all alumni earning physics PhDs, which I approximate based on the number of PhDs earned over the 5 year period, divided by the number of undergraduates (available from Wikipedia).</p>
<p>There are other methods to measure and compare PhD productivity (for example, normalizing by program size, i.e. measuring only the percentage of physics majors who go on to earn physics PhDs). Using this method, according to my calculations based on Common Data Set data (section J, “degrees conferred”), the colleges where the greatest percentage of physics majors go on to earn physics PhDs (> 20%) include: Caltech, Harvey Mudd, Swarthmore, and Lawrence. The colleges where the next greatest percentage of physics majors go on to earn physics PhDs (10% - 20%) include: MIT, Harvard, Princeton, Berkeley, Stanford, and Williams. I don’t have CDS data for Chicago. I haven’t calculated the percentage for every school listed above (nor for colleges not listed above). One might get a more accurate count of graduating majors by using IPEDS rather than CDS and enrollment data.</p>
<p>Of course, many strong physics (/astronomy) students, even in the best physics (/astronomy) programs, won’t choose to pursue graduate degrees at all. PhD productivity is but one possible outcome measurement (although I believe that of all available outcome metrics, it may be the one that best reflects department academic quality.)</p>
