For GRFP applicants reading their feedback
NSF GRFP Ratings Decoder and Reapply Plan
Your NSF GRFP feedback in plain words: what your band and ratings mean, whether you can apply again, and what to change first.
Free to start. No card needed.
How to read your GRFP feedback yourself
To read your GRFP feedback, start with the ratings, not the band, because the ratings show which criterion needs work. Save a copy of everything the GRFP module shows, then line up your Intellectual Merit and Broader Impacts ratings side by side. One lower rating among strong ones may be one reader's view, but the same lower rating from everyone usually means your statements never made the case. NSF 26-5261 calls each criterion "necessary but neither, by itself, is sufficient," so a strong one can't carry a weak one.
If your feedback is from 2025 or earlier, sort each written comment into a strength or a fix, and tie every fix to a paragraph. GRFP Help2, an unofficial site that shares past applicants' essays, posts the 2025 ratings sheet of an applicant named an Honorable Mention despite five Excellent ratings out of six. One reviewer's Excellent for Intellectual Merit came with a fix: "If explicit hypothesis was stated it would have further strengthened the proposal." The next year, the applicant won with a new wetland plan listing four numbered hypotheses.
Feedback from the 2026 competition came without comments, so use NSF's own review factors as your checklist. For Intellectual Merit, reviewers consider abilities such as "Plan and conduct research" and "Persist and overcome challenges"; for Broader Impacts, outcomes such as "Increase participation in STEM." Mark each factor that your statements support with a specific example, and the gaps behind a weaker rating usually show. Rules shift too: NSF 26-5261 dropped the STEM Education and Learning Research field and now excludes research on conservation practice, so check the GRFP eligibility guide before you rewrite.
How it works
What do GRFP ratings and bands mean?
GRFP ratings and bands are the feedback NSF gives reviewed applicants once fellowship offers are out. For the 2026 competition, which took applications in fall 2025, NSF's FAQ3 says applicants receive a band rank and qualitative ratings for Intellectual Merit and Broader Impacts. The band roughly places your application among the others in your field's review panel. NSF collected no written comments for that competition and hasn't said which bands lead to a fellowship, so your ratings are the part you can act on.
River's ratings decoder reads what you paste or drop, from a 2026 band and ratings to an older sheet full of reviewer comments. It lays out every rating by criterion, says what NSF has and hasn't said, and answers whether you can apply again under NSF's current rules. Then it ranks up to five changes, pointing to exact paragraphs when you add the statements you submitted. It never guesses your odds, and it never changes your files.
The 2026–27 cycle is closed: letters were due October 16, 2026, applications October 19 to 23, and NSF expects results by early April 2027. NSF hasn't announced next year's dates, so watch for its next solicitation; this cycle's came out August 25, 2026. If you can apply again, test your topic with the eligibility checker, and if Broader Impacts was your lower rating, rebuild that section with the Broader Impacts builder. Then get a panelist's read of the new draft from the mock review.

A doc with what your ratings mean, whether you can apply again, what to change first and a plan.
Revise and recheck
Ask River to revise your weakest section in a new doc, or review the new draft like a panelist.

What you'll get
What your band and ratings mean, and what to change next
- Your band and ratings in plain words, and what NSF has and has not said about them
- Whether you can apply again under NSF's current rules, and when
- The sections to change first, tied to your weakest criterion
Before and after
Your ratings in. A plan out.
Application Band: Band 2. Quality Ratings, Intellectual Merit | Broader Impacts: Excellent | Very Good, Excellent | Good, Very Good | Very Good. I applied as a senior, graduated in May and now work as a lab technician.
Your ratings lean strong on Intellectual Merit and softer on Broader Impacts, where no reviewer rated you Excellent. Can you reapply? Yes, under NSF's current rules, since you haven't enrolled in a graduate program. Next year's deadlines aren't out yet. Change first (general advice until you add your statements): make your Broader Impacts plans specific, with who, where, how often and how you'll know they worked.
NSF has not published how bands map to awards, so River reads your ratings for direction, not odds.
What lands in your doc

Questions GRFP applicants ask
Common questions
What does a GRFP band mean?
It shows roughly where your application ranked in your field's review panel. NSF's FAQ3 says the band and ratings offer "insight into how their applications were ranked relative to others within their field of study review panel." NSF hasn't published how bands map to fellowships or Honorable Mentions, so read your band as a position and your ratings as the guide to what to change.
Why didn't I get written reviewer comments?
Because NSF didn't collect any for the 2026 competition. Its FAQ says "No written reviewer comments were collected as part of the 2026 GRFP review process," so applicants get a band and ratings instead. Sheets from 2025 and earlier gave each reviewer's written explanation, and you can read real ratings sheets next to their essays. NSF hasn't said what 2026–27 applicants will get.
What does Honorable Mention mean on the GRFP?
It's NSF's recognition for strong applicants who weren't offered a fellowship, and it carries no funding. NSF 26-5261 says it "is considered a significant national academic achievement," and NSF named 1,470 Honorable Mentions in the 2026 competition, alongside 2,500 fellowships. Upgrades can happen: in June 2025, after first offering only 1,000 fellowships, NSF offered full fellowships to 504 people on its Honorable Mention list, C&EN reported4.
Can I reapply to the GRFP?
It depends on your stage. Under NSF 26-526, seniors and bachelor's graduates who have never enrolled in a graduate program can apply unlimited times. Graduate students get one try, in the first year of their first graduate program, and second-year students can't apply. So if you applied as a senior and started graduate school in fall 2026, the October 2026 deadline was your last chance under the current rules.
When does GRFP feedback come out?
After NSF makes its fellowship offers, which it expects by early April. NSF's information for reviewers5 says applicants can view what reviewers provided once offers are made. NSF then emails each reviewed applicant when the assessment is ready in the GRFP module. It doesn't publish a release date, so watch your email and save a copy as soon as it arrives.
How do I decode my GRFP feedback with River?
Paste your band and ratings into the box at the top of this page, or drop your ratings sheet, and add your statements if you have them. Under River's privacy policy, none of it is used to train AI models. River explains what your ratings mean, whether you can apply again and what to change first, in a doc in your free River workspace.
Is the GRFP ratings decoder free?
Yes, it is free to start. Your decoded feedback opens in a River workspace, where you can edit it, share it with an advisor or ask River to change it. Paid plans add more AI use and access to the most advanced models.
