<p>I don’t know. I never applied as an undergrad, so I can’t tell you. It really depends on the graduate department you are looking at, and the subprogram within the department. I had cross-registered at MIT and my research resume and the recommendations did it for me, I imagine.</p>
<p>Graduate school admissions (everywhere, not just at MIT) are done by department, so it’s meaningless to talk about “grad student admissions” without the context of a particular department or field’s admissions practices.</p>
<p>Many of MIT’s graduate programs do have lower admit rates than the undergraduate program, and the competition is much stiffer.</p>
<p>I know from personal experience that the biology department interviews about a third of applicants and accepts about half of interviewed students (17%).</p>
<p>And some of the department admit rates are misleadingly high – from information I’ve seen, aero/astro has a high admit rate overall, but they admit virtually 100% of applicants who did their undergraduate work at MIT. The admit rate for applicants from outside MIT is much lower.</p>
<p>You can find a lot of them at petersons.com. Keep in mind that they don’t separate master’s from PhD admissions when they display the rates, though.</p>
<p>Also this:</p>

<p>A lot of the MIT grad departments favor their own (though not all - physics and math, for instance, pretty much won’t take their own).</p>
