An NSF panelist is an outside expert who reads and rates a group of proposals for the National Science Foundation and then discusses them with other reviewers, either in person or virtually. The role is a volunteer route, not an application: you register in Research.gov, tell the relevant program staff what you know, and wait to be invited. This guide lays the whole path out in order, from volunteering through the payment condition that catches panelists out. Everything below is as described on the official NSF pages on 2026-10-29.

Suggested question: “How do I become an NSF reviewer?”
What it is and who runs it
NSF’s merit review can use “ad hoc reviewers, a panel of experts, or a combination of both.” NSF program officers typically identify the external reviewers, who are experts in the fields the proposals represent. A program officer manages each panel. Reviewers assess every proposal against NSF’s two criteria, Intellectual Merit (advancing knowledge) and Broader Impacts (benefit to society); the full criteria, rating scale and conflict rules are in the NSF merit review panel entry. Reviewer input is one factor in NSF’s portfolio decisions, not the decision itself.
A panelist reviews a relatively large number of proposals, rates each one, and takes part in a multiday discussion that can be held in person or virtually. For the wider funding picture, see the NSF grants overview.
Eligibility
NSF’s volunteer page lists no formal eligibility criteria. It states that NSF welcomes “qualified reviewers from academia, industry, nonprofits and the government sector.” Selection is made by program staff for each meeting, so volunteering does not guarantee an invitation. Providing demographic information when you register is voluntary, there is no adverse consequence for declining, and the information is protected under the Privacy Act.
What the role requires
- A Research.gov reviewer profile (new or updated), with multi-factor authentication. NSF’s panelist page says NSF began requiring MFA on Oct. 27, 2024. The invitation code in your email starts a five-step profile process.
- Form 1230P, “NSF conflicts-of-interests and confidentiality statement for NSF Panelists.” You disclose potential conflicts and agree to keep proposals and applicant identities confidential.
- A conflict-of-interest briefing video before the meeting.
- The reviewer orientation video “The art and science of reviewing proposals” (20 minutes), if you have not viewed it in the past 12 months.
- Travel and reimbursement registration (personal and banking information) before meeting day, even if the panel is virtual.
- Written reviews prepared in the Proposal Evaluation System (PES).
Application and participation steps
1. Volunteer
Register on Research.gov by completing the volunteer-to-review process and listing your areas of expertise. Then contact the directorate or program. Several directorates (BIO, CISE, ENG, GEO, MPS, EDU, GRANTED, EPSCoR and GRFP) have their own interest survey or form. For the others, email the program officer or officers whose work fits yours from your registered email address, introduce yourself, name your expertise and attach a two-page CV with current contact information.
2. Accept the invitation and finish your profile
Use the invitation code to complete the five-step profile. Find the meeting in Research.gov under Reviews, panels and other meetings, on the Panels and meetings tab, click the meeting ID and accept the legal notices. If PES shows an error, the one-time profile setup may be outstanding; look for the email with the subject “NSF – Action Needed: Provide Reviewer Profile Information.”
3. Sign Form 1230P
Complete it from the Meeting details page and sign electronically. NSF emails a confirmation to the program officer and the meeting coordinator.
4. Register for travel and reimbursement
Do this before the meeting day. If you travel, airline and train tickets must be purchased by the NSF travel agency. In-person panelists are reimbursed for travel to NSF headquarters in Alexandria, Virginia.
5. Write your reviews in PES
The review form has an optional Proposal Synopsis. Strengths and Weaknesses are required for both Intellectual Merit and Broader Impacts, solicitation-specific criteria appear only if program staff add them, and a Summary Statement is required. There is no character limit, and you select one or two ratings from six options. Reviews auto-save every 10 seconds but are visible to others only after you click “Submit to System.” Ratings and reviews can be updated until the panel is closed. Working comments are not part of the official record.
6. Attend and record attendance
For a virtual panel, test your setup beforehand; program staff send the meeting link. For an in-person panel, arrive at least 30 minutes early at the Panel Conference Center (second and third floors). Record your attendance each day.
7. Agree to the panel summary
The managing program officer appoints a Scribe, who drafts the panel summary and clicks Submit for Comments. Only the Scribe accepts or rejects edits, and only accepted edits are incorporated. Assigned panelists click Agree with Panel Summary, and everyone on the agreement list must agree. The panel’s recommendation is separate from the summary. For the cutoff date for summary changes, ask the program officer.
How payment works
In-person and virtual panelists receive a flat rate for their time; ad hoc reviewers are not reimbursed for time. The condition that is easy to miss: you are compensated only if you complete both the daily attendance check-in and the travel and reimbursement registration, and NSF requires that registration even for virtual panels. Missing either one leaves the payment incomplete.
Typical timeline phases
| Phase | What happens |
|---|---|
| Before the meeting | Volunteering, invitation, profile and MFA, conflict briefing, Form 1230P, travel and reimbursement registration, orientation video, drafting reviews in PES |
| During the meeting | Daily attendance check-in, multiday panel discussion, rating updates as needed |
| After the discussion | Scribe drafts the panel summary, panelists agree to it, the panel is closed and reviews can no longer be updated |
| Afterwards | NSF aims to tell applicants whether their proposals are declined or recommended for funding within six months |
Common mistakes
- Skipping travel and reimbursement registration for a virtual panel. It is still required for payment.
- Missing a daily check-in. You must record your attendance each day of the panel.
- Leaving Form 1230P unsigned. It carries both your conflict disclosure and your confidentiality commitment.
- Assuming a draft is shared. Auto-saved reviews stay private until you click Submit to System.
- Treating working comments as the record. They are not part of the official record.
- Editing the summary directly. Only the Scribe accepts or rejects edits.
- Buying your own tickets. Airline and train tickets must be purchased by the NSF travel agency.
Related roles
| Role | Proposals | Meeting | Time compensation |
|---|---|---|---|
| Panelist | A relatively large number, each rated | Multiday discussion, in person or virtual | Flat rate; travel reimbursed for in-person |
| Ad hoc reviewer | One proposal at a time, rarely two | No panel meeting | Not reimbursed for time |
Ad hoc ratings are passed to panelists after submission and before panel discussion. For proposers on the other side of the process, see NSF proposal types and the NSF PAPPG, which holds the conflict and confidentiality rules (Chapter III).
FAQ
How do I become an NSF reviewer?
Register on Research.gov through the volunteer-to-review process, list your areas of expertise, then complete the relevant directorate’s interest form or email the fitting program officers with a two-page CV.
Do NSF panelists get paid?
Yes. In-person and virtual panelists receive a flat rate for their time, and in-person panelists are reimbursed for travel. Payment requires both the daily attendance check-in and travel and reimbursement registration. Ad hoc reviewers are not reimbursed for time.
Can early-career researchers serve?
NSF’s volunteer page lists no formal eligibility criteria and says it welcomes qualified reviewers from academia, industry, nonprofits and the government sector.
What is the difference between a panelist and an ad hoc reviewer?
A panelist rates many proposals and joins a multiday discussion. An ad hoc reviewer reviews one proposal at a time, rarely two, with no panel meeting.
Can I change my review after submitting it?
Yes. Panelist reviews and ratings can be updated until the panel is closed.
