<p>As far as I know, no one does a TA while on fellowship. However, you might be able to slightly supplement the NSF with another fellowship or an RA (i.e. your advisor’s grant money). Like going from 30k/year to 34k/year. I don’t know of any cases where you can get the full 30k from NSF and the full 15-30k from another source and just add them to get 45-60k. If the school offers more money and doesn’t allow supplementing, then you would turn down NSF (your choice). More likely, the school wouldn’t offer that much funding for 5 straight years so you would delay either the school’s funding or the NSF’s funding and use them serially. E.g. school funding for 2 years, then NSF for 3 years.</p>

That is unlikely to occur. And in the case that it does, and you turn down NSF so that your school now pays your full stipend out of its pocket, I don’t think they’ll be too happy about that.</p>
<p>Most schools ensure that their NSF applicants don’t receive a lower stipend than their unfunded students. And some schools (WashU if I remember correctly) offer a little bonus for students who receive NSF.
As far as TAships, NSF just instituted a new policy this year that no fellows may accept any paid internships or jobs…so you can’t be a TA if there’s payment associated with it.</p>
<p>And you can’t receive more than 5k in stipends from any source if you get the NSF. Often schools will give you a 5k bonus as incentive for you to take the NSF: you get a little more money and they save a lot.</p>
