NIH Request for Information: Proposed Changes to Peer Review Reporting

NIH is seeking public feedback on proposed changes to how peer review outcomes are reported. Under the proposal, applications would be categorized as Most Competitive, Competitive, or Not Discussed, based on overall impact scores.

If implemented, applicants and NIH program staff would no longer have access to numerical overall impact scores or percentiles.

Comments are due October 13. Members of the research community are encouraged to review the proposal and submit feedback directly through the NIH RFI.
