<p>Grad School admissions are a horse of another color. Yes, your undergrad institution will matter to a certain degree, but it’s not the be all-end all to grad school admissions. Neither is the GRE in most cases. Graduate committees are more interested in what you’ve done while in school (internships, research), how well you’ve done academically, what your goals are and your potential as a future academic. This is often more strongly the case for PhD programs than terminal MA/MS programs. Particularly important for PhD programs (if that is your anticipated road to take) is how well your interests mesh with the faculty with whom you’d be working.</p>
<p>The other thing with grad schools is that the “best (undergrad) schools” generally, may not be the “best school” for your grad program, so even if the data was available, it may not be meaningful to you unless you know your academic specialty and the faculty available in different programs. Harvard may be ranked in the top #5 for your given academic discipline, but it doesn’t mean it will be the best fit for you both academically or professionally. Another “lower” ranked school may have the right faculty that you want to work with, and that is generally one of the most important aspects of graduate school searching.</p>
