About the program

The GRFP funds people, not projects: a portable fellowship for research-based master’s and PhD students in NSF-supported fields, awarded early — senior year of undergrad or the first years of grad school — on the strength of the applicant’s potential. The proposed research plan demonstrates how you think; you are not bound to execute it.

Review runs on NSF’s two merit criteria, intellectual merit and broader impacts, weighted equally — and the broader-impacts half is where otherwise-strong applications die. Concrete, evidenced engagement (teaching, outreach, mentoring, community work, with outcomes) beats aspiration every time.

Who can apply

  • US citizens, nationals and permanent residents only.
  • Early-career limit: apply as an undergraduate senior, before starting, or once during the first two years of a graduate program (rules on prior enrollment are strict — read them).
  • Research-based MS/PhD programs in NSF-supported fields; clinical practice-oriented degrees are excluded.

Writing a competitive application

  • Give broader impacts equal wordcount and equal specificity — with receipts (what you did, for whom, with what result).
  • The personal statement should show a research arc: how each experience changed what you can do, not a chronological résumé in prose.
  • Ask recommenders to address both criteria explicitly; reference letters are scored against them too.
  • A feasible, hypothesis-shaped research plan with a named methodology reads better than a grand vision — reviewers know plans change.

Frequently asked questions

When is the GRFP deadline?
Annually in mid-to-late October, with the exact day varying by discipline group (and reference letters due shortly after). The current cycle’s dates are on nsfgrfp.org.
How many times can I apply to the GRFP?
Broadly: once as an undergraduate/pre-enrollment and once as an early graduate student. The enrollment rules are precise and unforgiving — verify your situation against the current solicitation before assuming eligibility.
Do I have to do the research I proposed?
No. The research plan is an evaluation instrument, not a contract — fellows routinely change projects, advisors and even subfields within NSF-supported areas.
