PA-25-426: Ruth L. Kirschstein NRSA Individual Fellowship for Dual-Degree Students at NIH-Funded Institutions (Parent F30)

PA-25-426: Ruth L. Kirschstein NRSA Individual Fellowship for Dual-Degree Students at NIH-Funded Institutions

If your institution has an NIH-funded Medical Scientist Training Program (MSTP), Dental Scientist Training Program (DSTP), or a similar NIH-supported predoctoral dual-degree pathway, PA-25-426 may fit your training plan. It is the companion to PA-25-425, which serves students at institutions without an NIH-funded institutional predoctoral dual-degree program. Check the institutional program and the participating NIH Institute or Center requirements before preparing an application.

This is an NIH parent Notice of Funding Opportunity (NOFO), rather than a one-time topic-specific call. Its research scope is tied to the missions of participating NIH Institutes and Centers, while its central purpose is support for integrated research and clinical training. PA-25-426 is active through its published expiration date, and its standard receipt dates recur on the schedule below.

The notice was posted June 13, 2025 and opened July 8, 2025. NIH announced in January 2026 that it was removing dedicated AIDS application due dates beginning with applications for the January 2027 Advisory Council review. The listed AIDS dates after the policy change are therefore not additional submission opportunities; applicants should use the standard receipt dates in the current notice and applicable NIH policy.

Key details at a glance

The stipend and allowance figures are NIH-wide FY2026 NRSA levels, not a guaranteed total award amount. The award combines the applicable stipend with tuition and fees and the appropriate institutional allowance. Amounts depend on the fiscal-year funding rules and the candidate’s institution; NIH’s FY2026 notice is the source for these figures.

Why this opportunity matters for 2026/2027 planners

For teams building a near-term calendar, PA-25-426 remains open. The August 8, 2026 standard due date has passed, but the next listed standard date is December 8, 2026, followed by additional cycles through April 8, 2028. These are fixed submission dates, not a rolling application window. Allow time for institutional registrations, reference letters, internal review, and NIH validation before each date.

Candidates should plan around the dates in the NOFO and their institution’s internal deadlines. NIH encourages early submission so errors found during processing can be corrected by the due date. The F30 award supports training over a mentored fellowship period; it does not reimburse the full cost of a dissertation research project.

The NOFO is also explicit about who it serves: students in formal dual-degree programs at institutions where those programs are already NIH-funded. This reduces ambiguity about institutional context. It does not replace topic selection; it defines the funding architecture around career-stage training and institutional environment.

Consider this opportunity for the December 2026 or later cycle if:

• your trainee is in a formal dual-degree program with a clearly defined dissertation project,
• the institution has NIH-supported predoctoral dual-degree structures,
• and the requested award period can devote at least half its time to full-time graduate research training leading to the research doctorate.

What PA-25-426 actually covers

This opportunity exists to support research and clinical training integration for selected dual-degree predoctoral students. The NOFO is clear: the fellowship is for predoctoral candidates pursuing combined professional and research doctorates through a dual-degree path, with a mentoring and research-training experience intended to strengthen transition into independent research leadership.

It is not a project-only scholarship; it is a fellowship training instrument. The funding model includes stipend, tuition/fees support, and institutional allowance for health insurance, supplies, equipment, travel to scientific meetings, and other fellowship training costs.

The NOFO also states that no separate Facilities & Administrative (F&A) reimbursement is provided; the institutional allowance absorbs administrative and fellowship support structure. This is an important budget implication for sponsor teams that assume normal grant overhead language applies.

The NOFO sets the candidate’s core mission as:

• strengthen the candidate’s rigor in research design, experimental methods, and quantitative analysis,
• deepen transition toward scientific independence as a clinician-scientist pathway,
• and require integrated clinical and research training as part of a supported trajectory.

Exact eligibility gates: where teams often fail early

The first step is understanding the NOFO’s institutional and candidate splits. Because PA-25-426 and PA-25-425 are easy to confuse, teams often submit to the wrong parent path.

Institutional eligibility gate

The NOFO states eligibility is limited to applicant organizations with NIH-funded institutional predoctoral dual-degree programs, including NIH-supported MSTP or DSTP structures or similar programs.

This means:

• You generally need institutional context where the candidate is enrolled in a dual-degree path with an NIH-supported framework,
• Applicant organizations must be eligible under the NIH Grants Policy Statement and complete required registrations,
• But foreign entities are not eligible as primary applicants,
• The sponsoring institution must provide an actual training environment, not just administrative support in name.

Candidate gate: dual-degree status and stage

The NOFO defines a candidate pathway in detail:

• Candidate must be in a formal dual-degree program,
• Must have identified a dissertation research training project,
• Must have one or more sponsor(s), and
• Should be able to show integration of professional and research training goals.

The NOFO is explicit on timing:

• Most MD/PhD and DO/PhD candidates should apply within 48 months of matriculation and no later than 24 months into dissertation research training,
• Across dual-degree tracks, the fellowship should prioritize research training, with most of the support period directed toward graduate research,
• The NOFO requires at least 50% of total award time generally devoted to full-time graduate research leading to the doctoral research degree,
• Overly late applications can fail even before review if the training timeline is inconsistent with this expectation.

Exception pathways are possible for non-standard dual-degree structures and approved leave cases, but these need justification and documentation.

Legal and individual status gate

The NOFO requires the fellowship candidate (PD/PI level in this mechanism context) to be a U.S. citizen, non-citizen national, or lawful permanent resident by the time of award. This is a common compliance point that teams discover too late when proposal content is nearly done.

Sponsorship gate

Applicants must identify sponsor(s) before submission. The sponsor team is not ceremonial:

• one primary sponsor must be designated and actively responsible,
• training supervision quality and alignment are explicitly reviewed,
• foreign components may be included when allowed under NIH policy; consult the NOFO and NIH staff about the proposed arrangement.

What the NOFO says about the application package

PA-25-426 requires the application package accessed through one of the electronic systems listed in the NOFO. Candidates and applicant organizations must follow the current NIH Fellowship (F) Application Guide together with the NOFO’s additional instructions. Noncompliant applications may be delayed or not accepted for review.

Accounts, registrations, and submission routes

The NOFO provides three electronic submission routes:

1. NIH ASSIST,
2. Grants.gov Workspace,
3. institutional system-to-system integration (with Grants.gov + eRA Commons).

Whichever route you use, the applicant organization must complete required registrations before submission. NIH warns registration can take six weeks or more and incomplete registration is not a valid reason for a late application. The organization needs an active SAM registration. The candidate (PD/PI) needs an eRA Commons account affiliated with the applicant organization, and the eRA Commons profile must be linked to a valid ORCID ID. Sponsors must include their eRA Commons IDs in the Senior/Key Person Profile credentials as required by the notice. Ask the institutional signing official and grants administrator to confirm the roles and registrations needed for the chosen route. Account setup can take time, so start well before the intended submission date.

Application sections that actually matter

PA-25-426 uses the Fellowship (F) application format. The PHS Fellowship Supplemental Form contains:

• Candidate section,
• Research training plan,
• commitment to mentoring and training environment,
• additional sections,
• budget,
• appendix.

Follow the current NIH Fellowship Application Guide and the program-specific instructions in PA-25-426, including page limits. Required reference letters use a separate process: referees submit them directly through the eRA Commons Submit Reference Letter link during the allowed period. They are not included in the Grants.gov application, and missing required letters mean the application will not be reviewed. Coordinate letter requests separately from the application upload.

For human subjects, clinical trials, and additional compliance forms, the NOFO cross-references the NIH application guide and requires exact completion of required records.

What review reviewers will score

The review framework is structured and hard to overprepare outside scope.

The three scored criteria

Reviewers score by:

1. Candidate’s Goals, Preparedness, and Potential

   • does the candidate’s background support the training design,
   • is there evidence of strong research understanding and motivation,
   • and will this fellowship plausibly increase long-term independence trajectory.

2. Research Training Plan

   • whether goals are coherent,
   • whether planned activities and milestones are realistic,
   • whether training addresses clear skill gaps,
   • and whether sponsor and environment can execute.

3. Commitment to Candidate, Mentoring and Training Environment

   • quality of mentorship structure,
   • depth and continuity of support,
   • feasibility of training milestones,
   • and whether environment aligns with intended research training outcomes.

A large share of scoring failure here comes from treating the candidate package as if it were a single-project grant. In this program, the candidate and mentoring story carries equal weight with the technical plan.

Additional review considerations (not scored, but influential)

Even when not scored directly, these are explicit in the process:

• responsible conduct of research (RCR) plan quality,
• safety and biosafety,
• bioresources and data sharing, including resource-sharing commitments,
• resource authentication where needed,
• human subjects, and
• budget justification against requested duration.

RCR has non-trivial explicit detail in the NOFO: a complete training plan is required with appropriate format, subject matter breadth, faculty participation, at least eight contact hours, and repeated instruction over time.

Selection logic after review

The NOFO states that top half applications generally move into deeper scoring dynamics, with secondary-level NIH Institute or Center review applying relevance, merit, and fund availability. This is standard NRSA but worth restating for candidate expectation management: reviewer scoring is only part of the process.

Submission timeline and planning strategy

The next standard due date after the August 8, 2026 cycle is December 8, 2026. The notice also lists standard dates on April 8, 2027, August 8, 2027, December 8, 2027, and April 8, 2028. Its listed expiration date is May 8, 2028. Applications are due by 5:00 PM local time of the applicant organization. NIH’s January 2026 policy notice removes AIDS-specific due dates for applications intended for the January 2027 Advisory Council review and later; use the standard dates for these cycles, not an AIDS-only date.

For a December 2026 submission, work backward from the official due date and allow time for institutional review and NIH processing:

• About three months ahead: confirm the candidate and institutional pathway qualify; agree on the sponsor team, proposed training period, and research project.
• About two months ahead: check SAM, eRA Commons, and institutional submission registrations. Ask referees to plan for the separate reference-letter process.
• About one month ahead: assemble the PHS Fellowship Supplemental Form and other SF424(R&R) components using the current Fellowship Application Guide and the NOFO’s additional instructions.
• In the final weeks: check page limits, required forms, human-subjects or clinical-trial information if applicable, credential fields, budget, and reference-letter receipt. Follow the institution’s internal deadline.
• By the due date: submit through ASSIST, institutional system-to-system, or Grants.gov Workspace early enough to review the assembled application in eRA Commons and address errors before the 5:00 PM local deadline.

The NOFO text explicitly recommends early submission due to correction cycles. Teams should not interpret the deadline as a binary “single-shot” line item.

Common mistakes in PA-25-426 applications

1. Applying under the wrong F30 parent NOFO

   • Institutions with NIH-supported dual-degree programs should use this mechanism; institutions without should use PA-25-425.

2. Late sponsor identification or weak sponsor alignment

   • if sponsor readiness is unclear, the review process penalizes that early and harshly.

3. Overlooking the 50% research training requirement

   • in dual-degree paths, time split matters. The NOFO language is explicit about research-time composition.

4. Incomplete registrations or credentials

   • The applicant organization needs active required registrations. Candidate and sponsor eRA Commons identifiers and the candidate’s ORCID link must be correct before submission.

5. Submitting before checking timeline fit for dual-degree candidacy

   • candidates beyond accepted training stage boundaries or with weak dissertation alignment lose credibility at compliance and scoring stages.

6. Treating compliance attachments as optional

   • limited Appendix and strict e-forms process means administrative precision is a reviewer-side risk reducer.

7. Underestimating foreign component justification

   • foreign training is possible but not automatic; scientific advantage must be explicitly proven.

What to prepare: a reviewer-aligned package

A strong PA-25-426 application is a coherent sequence of five proofs:

1. Candidate readiness proof

   • explain the training need and why now is the right point in the dual-degree timeline.

2. Mentoring proof

   • sponsor commitment, environment capacity, measurable milestones.

3. Methods and skills proof

   • clear training activities, milestones, and measurable output pathway.

4. Compliance proof

   • registrations, identity/credentials, form instructions, letter process, and policy checklists.

5. Execution proof

   • how the project and training will be managed in calendar terms with realistic full-time effort expectations.

Frequently asked questions

Does PA-25-426 have a fixed amount?

No single dollar total is printed in the NOFO in the same format as a fixed award ceiling. The funding structure is component-based (stipend, tuition/fees, institutional allowance) and NIH updates amount details through policy channels and current NRSA guidance. For application planning, budget rates should be pulled from current NIH NRSA policy notices and current fellowship links.

Who is this pathway for?

Predoctoral dual-degree trainees at institutions with NIH-funded dual-degree infrastructure, including MSTP and DSTP-like contexts, where the candidate has an identifiable dual-doctoral training plan and dissertation research project with mentoring support.

Is this only for MD/PhD students?

No. The NOFO explicitly references broader dual-degree formats such as DO/PhD, DDS/PhD, AuD/PhD, DVM/PhD, and similar combinations.

Can the training include clinical exposure?

Yes, integrated clinical experiences can be part of the training plan when they align with the candidate’s program structure and research training trajectory.

Can fellows renew?

Individual fellowship awards are generally not renewable. Rare continuation needs are possible but not the default and require specific advisory paths.

Can candidate-led independent clinical trials be proposed?

No. The NOFO explicitly restricts candidate-led independent clinical trials, but sponsor-led training experiences are possible in defined conditions.

Can non-U.S. institutions apply?

Foreign organizations are not eligible as principal applicants. U.S. applicants can involve foreign components where policy allows and only where scientific advantage is justified.

Preparation playbook for institution teams

The most effective teams treat this as a 3-layer readiness process:

• Pathway fit check: confirm candidate institution category and dual-degree timing.
• Process readiness check: verify registrations, accounts, and ORCID completion by at least two weeks before submission.
• Content coherence check: align candidate story with mentor statement, training plan, budget, and facilities.

In many cases, the process readiness layer is where teams lose cycles; the scientific layer is usually salvageable.

A practical template:

• Week 1: confirm candidate is in eligible institutional context,
• Week 2: map training milestones and 50%-research-time expectation,
• Week 3: final sponsor mapping and mentorship plan,
• Week 4: build section-by-section checklist against NIH fellowship form rules,
• Week 5: final compliance run including reference letters and SAM/eRA status,
• Week 6: dry-run submission and correction buffer.

How PA-25-426 compares with nearby alternatives

If your institution does not have NIH-funded dual-degree infrastructure, PA-25-425 (partner pathway for non-MSTP/DSTP settings) is likely the correct route. If it does, PA-25-426 is the right structural match.

If your candidate is postdoctoral, PA-25-423 is generally the applicable framework. If you need fully senior-stage retraining support, PA-25-424 is the pathway for established investigators.

This sibling-set structure is important: the difference is not prestige, but institutional and career-stage fit.

Bottom line

PA-25-426 is the right NRSA parent route when both of these are true:

1. your dual-degree program sits in an institution with NIH-funded predoctoral dual-degree infrastructure,
2. the candidate is early to mid-stage in a formal dual-degree training arc and can document a rigorous sponsor-guided training plan.

For 2026/2027, it remains a practical and active route because of recurring cycles and consistent review architecture. The strongest applications are not just scientifically strong; they are administratively precise, sponsor-aligned, and candid about timeline and training feasibility. If those conditions are met, this is one of the most structured ways to secure NIH-backed dual-degree training support.
