Individual fellowships and career awards (F30, F31, F32, F99/K00, K99/R00)

Institutional programs need a campus with an award. Individual fellowships don't. A student or postdoc applies with a sponsor, and the award follows that person's project.

Short answer

Individual NIH fellowships (F30, F31, F32) are applied for by the trainee with a sponsor, use standard due dates of April 8, August 8 and December 8, and require US citizenship, noncitizen national status or permanent residency. The K99/R00 Pathway to Independence award has no citizenship requirement and uses February 12, June 12 and October 12.

What are individual fellowships?

Individual fellowships are NIH awards that a student or postdoc applies for personally, with a faculty sponsor, to fund a specific research training plan. They differ from institutional programs such as T32s, where the institution holds the grant and appoints trainees to slots.

Which award fits which stage?

Award Stage Citizenship Standard due dates
F30 MD/PhD student NRSA rules (citizen, national, permanent resident) April 8, August 8, December 8
F31 PhD student NRSA rules April 8, August 8, December 8
F32 Postdoc NRSA rules April 8, August 8, December 8
F99/K00 Late PhD into postdoc Set by the announcement Set by the announcement
K99/R00 Postdoc moving to independence No citizenship requirement February 12, June 12, October 12
K08, K23, K25 Clinician or quantitative researchers in early career Citizens, nationals or permanent residents for most mentored K awards February 12, June 12, October 12

When a standard date lands on a weekend or federal holiday, it moves to the next business day. The timeline builder applies that rule for you.

How do fellowships fit with the 2025–2026 changes?

They are the most stable part of the landscape. The institutional programs that ended in 2025 were mostly diversity-focused T32, T34, R25 and K12 programs. The parent fellowship announcements continued, and NIGMS still lists them in 2026. For a student whose campus lost an IMSD or G-RISE award, the F31 is often the most direct way to keep funded, structured training.

A practical note for NIGMS's F30: it is meant for students at institutions without an NIH-funded dual-degree training program. Students at MSTP institutions are generally expected to be supported through the MSTP.

What makes an application competitive?

Reviewers read fellowships as training plans, not just research proposals. Strong applications show a sponsor with funding and a track record of training, a specific plan for skills the applicant doesn't have yet, and a project the applicant can realistically finish. An individual development plan is a good starting draft for the training section.

Questions people ask

Can I hold an F31 while I'm on a T32?

Not at the same time for the same period; NRSA support can't be stacked. Many students move from a T32 slot to an F31 when the fellowship is awarded, which frees the T32 slot for someone else.

Does every NIH institute accept F31 applications?

Most do, but each institute sets its own policies, and some don't accept every fellowship type. Check the participating-institute table in the parent announcement and the institute's own fellowship page.

Can international postdocs apply for a K99/R00?

Yes. The K99/R00 has no citizenship requirement. It does cap how much postdoctoral experience you can have when you apply, so check the window in the current parent announcement.
