Searches for “NIH authorship guidelines” usually assume NIH issues its own authorship rulebook the way ICMJE or a journal does. It doesn’t — not for the roughly 80% of NIH’s budget that funds extramural research at universities and other institutions. For extramural grantees, NIH does not define who qualifies as an author on a resulting publication; that determination is left to the authors themselves, applying whatever standard the target journal enforces (almost always the ICMJE authorship criteria). Where NIH policy does touch authorship, it does so indirectly, through grants-administration mechanisms, and in one specific case — NIH’s own intramural research program — directly, through an internal policy that applies only to NIH’s in-house scientists, not to grant recipients anywhere else.
This guide separates those threads: what NIH actually requires of grantees, what NIH requires of its own intramural staff, and where each connects to the broader authorship and contributorship standards research administrators already work with.
NIH has no independent authorship standard for grant-funded research
Nothing in the NIH Grants Policy Statement defines authorship criteria for papers arising from NIH-funded extramural research. NIH’s own Office of Intramural Research states plainly that “NIH generally follows the ICMJE recommendations” — and that statement is made in the context of NIH’s internal guidance to its own researchers, not a rule NIH imposes on outside grantees. In practice, this means:
- NIH does not adjudicate authorship disputes on grant-funded papers. That responsibility sits with the authors and, if needed, their institution and the publishing journal — the same allocation of responsibility ICMJE itself specifies: authorship determination is “the collective responsibility of the authors, not the journal.”
- NIH does not require a specific number of authors, a specific author order, or a specific contributorship disclosure format (such as a CRediT statement) as a condition of an award. Individual journals may require these; NIH as a funder does not.
- NIH’s Public Access Policy (governing deposit of NIH-funded peer-reviewed manuscripts into PubMed Central) requires acknowledgment of NIH funding and compliance with a repository-deposit timeline — it does not touch who is listed as an author.
So when a research administrator or investigator is asked “what does NIH require for authorship,” the accurate answer is: NIH defers to whatever authorship standard the publishing journal enforces, and in practice that is almost always ICMJE’s four criteria (contribution to the work, drafting or substantively revising it, final approval of the version published, and agreement to be accountable for it).
Where NIH grants policy actually intersects with authorship
Although NIH does not define authorship criteria, several grants-administration requirements sit adjacent to authorship and are frequently confused with an “authorship policy”:
Multiple PD/PI Leadership Plans
When an application designates more than one Program Director/Principal Investigator, NIH requires a Leadership Plan describing governance across the collaborating PIs — decision-making process, resource allocation, conflict resolution, and, specifically, how publication and authorship decisions will be made among the participating investigators. This is a grants-administration requirement (part of the application, reviewed for scientific merit) rather than an authorship standard in itself: it requires a plan for making authorship decisions, not a definition of who qualifies.
Biosketch “Contribution to Science” reporting
Every senior/key person on an NIH application must submit an NIH biosketch, which historically included a “Contribution to Science” narrative describing up to five significant contributions, each supported by up to four citations. As of applications due on or after January 25, 2026, this narrative format was replaced by the structured NIH Biographical Sketch Common Form. Either version documents an individual’s track record of contributions to the field — useful evidence for reviewers assessing an investigator’s qualifications — but it is not an authorship-eligibility test and doesn’t determine who should be listed as an author on any specific paper.
Data management, sharing, and acknowledgment requirements
NIH’s Data Management and Sharing Policy and the NIH Public Access Policy both require compliance steps tied to publication (a Data Management and Sharing Plan; PMC deposit and an NIH funding acknowledgment), but neither specifies authorship criteria for the resulting paper.
The one place NIH does have its own authorship policy: intramural research
The exception to “NIH has no authorship policy” is scoped narrowly: NIH’s Intramural Research Program (IRP) — NIH’s own in-house laboratories and scientists, as distinct from the extramural grantees at outside institutions — maintains internal authorship resources through its Office of Intramural Research (OIR). These include:
- A graphic developed by the NIH IRP Committee on Scientific Conduct & Ethics, “Research Contributions to Consider When Making Authorship Decisions,” laying out typical roles and the circumstances under which each may merit authorship.
- An explicit pointer to the ICMJE recommendations as the baseline standard, plus a reference to the CRediT Contributor Roles Taxonomy as a useful framework for identifying and resolving disputes over the many distinct types of contribution that can merit authorship.
- A formal NIH IRP Authorship Conflict Resolution Policy for adjudicating disputes among NIH intramural staff — something ICMJE itself explicitly leaves to authors and institutions to work out.
- A manuscript clearance step: papers with NIH-affiliated authors from the intramural program go through an internal approval process before submission, separate from journal peer review.
The scope matters: this policy governs NIH’s own employees publishing as NIH scientists. It has no bearing on a university-based investigator’s NIH R01, U01, or other extramural award — those researchers follow their institution’s and target journal’s authorship standard, not an NIH-specific one.
What this means in practice
| Situation | Who sets authorship criteria |
|---|---|
| Extramural NIH grant (R01, U01, K-series, T32, etc.) at a university or other outside institution | The authors, applying the target journal’s policy — almost always ICMJE’s four criteria |
| Multiple PD/PI extramural award | Same as above, but the Leadership Plan must describe the process for reaching those decisions among co-PIs |
| NIH Intramural Research Program (NIH’s own in-house scientists) | NIH IRP’s internal authorship guidance, which itself defers to ICMJE and adds an internal conflict-resolution process and pre-submission clearance step |
Frequently asked questions
Does NIH require a CRediT statement for grant-funded publications?
No. NIH does not mandate a CRediT contributor-roles statement as a condition of a grant award. Many journals do require one independent of the funder — see CRediT author statement samples for how that’s typically formatted.
Does the NIH biosketch determine who should be an author on a paper?
No. The biosketch (Contribution to Science narrative, or the current Biosketch Common Form) documents an investigator’s track record for grant review purposes. It’s evidence of past contributions, not a mechanism for deciding authorship on any given manuscript. See the NIH biosketch worked example for the current format.
If NIH doesn’t set authorship rules, who resolves an authorship dispute on an NIH-funded paper?
For extramural awards, the authors themselves, typically with input from their institution’s research integrity office if they can’t agree — NIH is not the adjudicating body. See resolving authorship order disputes. The one exception is NIH’s own intramural program, which has its own internal conflict-resolution policy for its employees.
Is NIH’s Public Access Policy an authorship policy?
No. It requires that NIH-funded peer-reviewed manuscripts be deposited in PubMed Central and that NIH funding be acknowledged; it does not define or constrain who is listed as an author.
