<p>[Department</a> of Mathematics at MIT | Graduate Study : Financial Aid](<a href=“Graduate”>Graduate)</p>
<p>Padad, not all the math programs are fully funded via TA or RA positions. My understanding is that MIT’s math Ph.D. program does not 100% fund all of its students (which isn’t to say some aren’t 100% funded for tuition plus heath plus a stipend, but simply that according to that site, some aren’t even 50% funded and those students don’t qualify for health insurance coverage on the university’s tab either). I suspect some other doctoral programs also don’t fully finance all students, and for master’s programs, I would expect the funding to be less common than for the doctoral programs.</p>
