Section I. Funding Opportunity Description
The overall goal of the NIH fellowship, research training, and career development programs is to help ensure a highly trained, heterogeneous pool of scientists is available across appropriate scientific disciplines to address the Nation's biomedical, behavioral, and clinical research needs. NIH fellowships support the training of predoctoral and postdoctoral scientists, dual-degree investigators, and senior researchers. More information about these fellowships is available on the NIH Research Training and Career Development website.
Note: This Notice of Funding Opportunity (NOFO) does not allow candidates to propose leading an independent clinical trial. However, candidates may propose research experience in a clinical trial led by a sponsor or co-sponsor.
Purpose The purpose of the Predoctoral to Postdoctoral Transition Award (Parent F99/K00) is to support promising graduate students as they complete their doctoral research training and transition to mentored postdoctoral career development opportunities in research areas relevant to the mission of participating NIH Institutes and Centers (ICs), preparing them to become productive, independent researchers.
Award Structure The F99/K00 provides up to 5 years of support across two consecutive phases.
| F99 Phase (Predoctoral): Provides 1 to 2 years of mentored research training to support completion of the research doctorate, including final experiments, dissertation preparation, and selection of a postdoctoral mentor. |
| K00 Phase (Postdoctoral): Provides up to 3 years of mentored postdoctoral research and career development support, contingent upon successful completion of the doctoral degree requirements and securing a postdoctoral position in a research area relevant to the mission of the participating NIH ICs. The K00 research direction should be within the mission area of the NIH IC that awarded the F99 phase. |
A K00 award will be made only to support a PD/PI who has successfully completed F99-supported training, secured a postdoctoral appointment, and, in coordination with the applicant institution, submitted to NIH a strong research and career development plan to be carried out in a supportive and rigorous research environment. Candidates are expected to obtain a postdoctoral position at an institution other than the one where they conducted their doctoral research.
Expectations Predoctoral students applying for the F99/K00 award are expected to propose an individualized research training plan for the final 1 to 2 years of predoctoral training, as well as a broad outline of up to 3 years of mentored postdoctoral research and career development activities that will prepare them for a productive, independent scientific research career in a biomedically relevant field.
The mentored research training and career development experience is expected to provide:
| a strong foundation in rigorous research design, experimental methods, and analytical techniques appropriate to the proposed research; |
| enhanced ability to conceptualize and think through research problems with increasing independence; |
| experience conducting research using appropriate, state-of-the-art methods, as well as presenting and publishing research findings as first author; |
| opportunities to interact with members of the scientific community at appropriate scientific meetings and workshops; |
| professional and scientific skills needed to transition to the next stage of the candidate's research career; and |
| opportunities to enhance and refine the candidate's understanding of the biomedical sciences and the relationship of the proposed research to health and disease. |
The F99/K00 award is intended for individuals who require at least 12 months of mentored research training in the F99 phase before transitioning to the K00 phase. Accordingly, individuals should propose a well-conceived plan for 1 to 2 years of substantive mentored predoctoral research training that will help them become competitive for postdoctoral research positions. An individual who cannot provide a compelling rationale for at least one year of additional mentored predoctoral research training at the time of award is not a competitive candidate for this fellowship.
Additional Information Because of the differences in individual Institute, Center, and Office (ICO) program requirements for this announcement, prospective candidates are strongly encouraged to consult the NIH Research Training and Career Development website to make sure that their application is appropriate for the requirements of one of the participating NIH ICOs.
Supported PD/PIs who can justify the need for additional mentored career development training beyond the K00 may work with their institutions to apply for additional NIH mentored career development awards.

F99 Eligibility: All institution/organization types listed above that grant PhD or equivalent research degrees (e.g., EngD, DNSc, DrPH, DSW, PharmD, ScD) are eligible to serve as a sponsoring institution. The sponsoring institution must have staff and facilities available on site to provide a suitable environment for performing high-quality research training. The training should occur in an environment that has appropriate human and technical resources and is demonstrably committed to training in the field(s) proposed by the candidate. All organizations with the appropriate resources and commitment are encouraged to apply. Multiple applications from an institution are allowed.
NIH Intramural Programs and other Federal laboratories are eligible to submit applications for the F99 phase (see note below).
K00 Eligibility: All institution/organization types listed above, with the exclusion of Federal laboratories, are eligible to submit K00 transition phase applications on behalf of individuals receiving support from F99 awards. There is no limit on the number of K00 awardees that an organization may sponsor.
Note: If the F99 candidate accepts a postdoctoral position in the NIH intramural research program or another federal agency, the postdoctoral phase will then be supported directly by the federal agency offering the postdoctoral position. The K00 will not be awarded, as federal employees are not eligible for NIH extramural grants. These postdoctoral scholars are invited to continue to participate in any relevant programmatic opportunities offered by the participating NIH Institutes and Centers.
An individual may request support for training abroad. In such cases, the candidate is required to provide detailed justification for the foreign training, including the reasons why the facilities, the sponsor, or other aspects of the proposed experience are more appropriate than training in a domestic setting. The justification is evaluated in terms of the scientific advantages of the foreign training as compared to the training available domestically. Foreign training will be considered for funding only when the scientific advantages are clear.
Foreign Organizations/International Collaborations
Non-domestic (non-U.S.) Entities (Foreign Organizations) are not eligible to apply.
Non-domestic (non-U.S.) components of U.S. Organizations are not eligible to apply.
Foreign components, as defined in the NIH Grants Policy Statement, are allowed.
NIH will no longer issue awards (i.e., new, renewal, or non-competing continuation) to domestic or foreign entities that involve foreign subawards/subcontracts. All NIH-funded research involving foreign subawards/subcontracts must be submitted in response to a NOFO that is specifically designated for funded international collaborations. See NIH Grants Policy Statement 16.8 Collaborative International Research Awards.
Applications involving foreign subawards/subcontracts submitted in response to this NOFO will be deemed noncompliant and will not be considered for funding. This policy applies to all monetary international collaborations resulting in foreign subawards/subcontracts, however, it does not preclude unfunded international collaborations or foreign components, funding for foreign consultants, or procurement of unique equipment or supplies from foreign vendors.
Required Registrations
Applicant Organizations Applicant organizations must complete and maintain the following registrations as described in the How to Apply - Application Guide to be eligible to apply for or receive an award. All registrations must be completed prior to the application being submitted. Registration can take 6 weeks or more, so applicant organizations should begin the registration process as soon as possible. Failure to complete registrations in advance of a due date is not a valid reason for a late submission, please reference NIH Grants Policy Statement Section 2.3.9.2 Electronically Submitted Applications for additional information.
System for Award Management (SAM) – Applicants must complete and maintain an active registration, which requires renewal at least annually. The renewal process may require as much time as the initial registration. SAM registration includes the assignment of a Commercial and Government Entity (CAGE) Code for domestic organizations which have not already been assigned a CAGE Code. Foreign organizations must obtain a NATO Commercial and Government Entity (NCAGE) Code (in lieu of a CAGE code) in order to register in SAM. Unique Entity Identifier (UEI)- A UEI is issued as part of the SAM.gov registration process. The same UEI must be used for all registrations, as well as on the grant application.
| eRA Commons - Once the unique organization identifier is established, organizations can register with eRA Commons in tandem with completing their Grants.gov registration; all registrations must be in place by time of submission. eRA Commons requires organizations to identify at least one Signing Official (SO) and at least one Program Director/Principal Investigator (PD/PI) account in order to submit an application. |
| Grants.gov Applicant organizations must have an active SAM registration in order to complete the Grants.gov registration. |
Program Directors/Principal Investigators (PD(s)/PI(s)) All PD(s)/PI(s) must have an eRA Commons account. PD(s)/PI(s) should work with their organizational officials to either create a new account or to affiliate their existing account with the applicant organization in eRA Commons. Obtaining an eRA Commons account can take up to 2 weeks.
All PD(s)/PI(s) must be registered with ORCiD. The personal profile associated with the PD(s)/PI(s) eRA Commons account must be linked to a valid ORCID ID. For more information on linking an ORCID ID to an eRA Commons personal profile see the ORCID topic in our eRA Commons online help.
Eligible Individuals (Program Director/Principal Investigator)
Any candidate(s) with the skills, knowledge, and resources necessary to carry out the proposed research as the Program Director/Principal Investigator (PD/PI) is invited to work with their sponsor and organization to develop an application for support. Multiple PDs/PIs are not allowed.
The candidate must be currently enrolled in a PhD or equivalent research degree program (e.g., EngD, DNSc, DrPH, DSW, PharmD, ScD) in the biomedical, behavioral, or clinical sciences at an eligible institution.
By the time of award, the individual must be a citizen or a non-citizen national of the United States or have been lawfully admitted for permanent residence (i.e. possess a currently valid Permanent Resident Card USCIS Form I-551, or other legal verification of such status).
At the time of award, the candidate must be in the dissertation research stage of training and is expected to require 1–2 years to complete their Ph.D. dissertation research training (F99 phase) before transitioning to mentored postdoctoral research training (K00 phase). If an individual begins a postdoctoral position or completes all Ph.D. dissertation requirements before an F99 award is made, neither the F99 award nor the K00 award will be issued.
Clinical Training and Health Professional Degrees Candidates must be enrolled in a research doctoral degree program that does not require post-degree clinical training. The Parent F99/K00 award may not be used to support studies leading to a MD, DDS, or other clinical, health-professional degree (e.g., DC, DMD, DNP, DO, DPM, DVM, ND, OD, AuD, PharmD, clinical PhD). The F99 and K00 phases are intended to be contiguous in time and cannot accommodate clinical training.
Dual-Degree Programs Students matriculated in a dual-degree program (e.g. MD/PhD, DO/PhD, DDS/PhD, or DVM/PhD) who seek support for both dissertation research training and clinical training are not eligible for the F99/K00 program because the F99/K00 does not support the clinical training component. Exceptions may be considered if there is no gap between the doctoral research training and postdoctoral phase, i.e., there is no clinical training period between completion of the PhD and the start of the postdoctoral research position. Students matriculated in a dual-degree program without a gap between the completion of the PhD and the postdoctoral phase should contact the appropriate IC program officer for approval prior to submitting an application. Alternatively, such students may apply for the Ruth L. Kirschstein National Research Service Award (NRSA) Individual Predoctoral MD/PhD or Other Dual-Doctoral Degree Fellowship (Parent F30) to support both dissertation research training and clinical training.
2. Cost Sharing
This NOFO does not require cost sharing as defined in the NIH Grants Policy Statement Section 1.2 Definition of Terms.

Candidate Section
Goals, Preparedness, and Potential All instructions in the How to Apply-Application Guide must be followed, with the following additional instructions:
This section should address both phases of the F99/K00.
A. Overall Training Goals Describe the long-term research and career goals and explain how the F99/K00 will enable the attainment of those goals. For each phase, describe how the proposed research training and career development plan will enhance the candidate's knowledge, technical expertise, and professional skills, keeping in mind existing strengths as well as any gaps in existing skills. Candidates are encouraged to discuss their alignment with the mission(s) of at least one participating NIH Institute/Center (IC). Consult IC Strategic Plans and the NIH Research Training and Career Development website for information on IC missions and areas of interest.
B. Candidate's Preparedness
| Address preparation for both phases of the F99/K00. |
| In this section, candidates may also provide an example of a challenge that they faced in research and have overcome using creativity and persistence. |
C. Candidate's Self-Assessment In addition to two to four specific areas of development during the F99 phase, include two to four specific areas of development during the K00 phase to attain the stated research training and career goals.
D. Scientific Perspective Address the scientific perspective of both phases of the F99/K00. Go beyond the information addressed in the Scientific Foundation and Rationale section of the Research Training Plan to demonstrate the significance of your specific research interests and goals in addressing key gaps in the broader scientific field.
Research Training Plan
Research Training Project Specific Aims and Strategy All instructions in the How to Apply - Application Guide must be followed, with the following additional instructions:
Training Activities and Timeline The plan and timeline must cover both the F99 and K00 phases of the award. The research training plan activities should not just be a list of activities; provide justification for planned activities based on your goals, strengths, and weaknesses identified in the candidate's self-assessment.
| Provide a timeline that spans both phases detailing the proposed research training, professional development, and other activities. For the F99 phase, describe planned activities in detail, by year. For the K00 phase, provide a broad overview of the desired scientific and professional activities. For both phases, identify the technical, conceptual, and analytical skills to be learned or enhanced during the award and how these will complement existing strengths and fill gaps, as described in the self-assessment. |
| For each phase, provide specific examples of how the proposed research training will facilitate the transition to the next career stage. If the K00 research direction is markedly different from the F99 research area, describe efforts and/or plans during the F99 phase training that provide preparation for the K00 research. |
| For the F99 phase, describe why the sponsor(s), collaborators, and research training environment are appropriate for the proposed research training plan and sufficient to address all the candidate's development goals. |
| For the K00 phase, a specific mentor does not need to be identified, but a plan for identifying and vetting a mentor(s) should be included, and an appropriate set of qualifications and mentor attributes should be described (research expertise, mentoring philosophy, etc.), as well as features of the postdoctoral scientific environment (resources, scientific specialization, size, etc). |
| When describing the collaborative process between the candidate and the sponsor(s) in preparing the research training plan, describe how the research training plan builds on current projects in the lab, while allowing the candidate to develop new skills and conduct research with increasing independence and intellectual contribution. |
Research Training Project - Specific Aims All candidates must use these two Specific Aims:
Specific Aim 1: The Dissertation Research Project.
Provide a detailed description of the overall dissertation research project, what has been accomplished to date (preliminary data may be included), and the research to be completed in the F99 phase.
Specific Aim 2: The Postdoctoral Research Direction.
Identify the research direction to be pursued for the K00 phase.
Research Training Project - Strategy Candidates should individually address the Scientific Foundation and Rationale and Approach for each Specific Aim and address the Scored Review Criteria indicated in Section V.1.
Specific Aim 1:
Scientific Foundation and Rationale
| Provide a thoughtful overview of the dissertation research, including the scientific question being addressed and its potential impact on the dissertation research field. |
| The Research Strategy should offer a clearly stated rationale and hypothesis, go beyond just experimental details, and provide perspective about the expected outcomes and significance. |
| Describe the strengths and weaknesses in the rigor of the prior research (both published and unpublished) that serves as the key support for the proposed project. |
| Explain how the proposed project will improve scientific knowledge, technical capability, and/or clinical practice in one or more broad fields. |
Approach The approach for this aim should be organized into two sections:
| A progress report on the dissertation research project thus far, including the approaches used, research outcomes obtained, and important methodologies learned and how they contribute to the long-term career goal; |
| A detailed research proposal for the work to be completed in the F99 phase, including experimental design, anticipated results, potential problems, alternative strategies, and potential follow-up studies, following the instructions in the How to Apply-Application Guide. Highlight new technical and professional skills to be learned and their contribution to the long-term career goal. Candidates must outline research and career development milestones for the transition from the F99 phase of the award to the K00 award phase. If the candidate is to gain experience in a clinical trial as part of their research training, describe the relationship of the proposed research project to the clinical trial. |
Specific Aim 2:
Scientific Foundation and Rationale
| Describe a specific scientific question or observation that will be investigated. Explain how this question or observation is related to the candidate's research interests and how this work will help advance this research direction. Explain the significance of and rationale for the K00 research direction. |
| The postdoctoral research plan does not have to be a continuation or within scope of the predoctoral research, but it should describe a logical trajectory from the predoctoral research to a productive career in the biomedical workforce. Explain how this question or observation is related to the candidate's research interests and how this work will help advance this research direction. |
| Describe the strengths and weaknesses in the rigor of the prior research (both published and unpublished) that serves as the key support for the proposed project. |
| Explain how the proposed project will improve scientific knowledge, technical capability, and/or clinical practice in one or more broad fields. |
Approach Provide a general description of how the research will be conducted, including approaches and methodologies to be used, anticipated results, challenges that might arise and how to address them. Career and professional development skills to be acquired should also be detailed.
Commitment to Candidate, Mentoring and Training Environment
| All instructions in the How to Apply - Application Guide must be followed, with the following additional instructions: | |
| If the candidate is proposing to gain experience in a clinical trial as part of his or her research training, the sponsor or co-sponsor must include a statement to document leadership of the clinical trial including source of funding, NCT# and appropriate expertise to guide the candidate in any proposed clinical trials research experience. The individual receiving support for the clinical trial (i.e., the sponsor/primary mentor or a co-sponsor) is the responsible individual of record for oversight of the trial though fellows can take part in all components of a clinical trial. Oversight includes (but is not limited to): interacting with relevant Institutional Review Board (IRB) staff; reviewing all informed consent documents; reporting potential serious adverse events; and maintaining responsibility for patient safety. However, the fellow can gain experience in all these components in conjunction with the mentor or individual leading the trial. |
| A. Mentoring Approach and Candidate Mentoring Plan | |
| The mentor must confirm that 1) the candidate is in a PhD program (include month and year of entry into the PhD program) 2) has reached the dissertation phase (include month and year of transition to dissertation phase) and 3) that the candidate has 1-2 years from the requested award start date before completion of their PhD (include month and year of anticipated graduation). | |
| The mentoring plan for the F99 phase should be individualized for the candidate and aligned with the Research Training Plan and the goals and activities identified in the Candidate section. It should not just be a list of activities; it should describe the candidate's strengths and gaps in needed skills, why these specific activities are appropriate for the candidate, and outline how the training plan will capitalize on the candidate's strengths and fill any gaps to help them achieve their stated career goals. | |
| Describe how the combined expertise of the sponsor, co-sponsor(s), collaborators, contributors, consultants, and/or advisory committee will ensure that all areas of the candidate's development and mentoring needs are adequately covered. | |
| Describe how the sponsor and co-sponsor(s) (as well as any collaborators, contributors, and/or consultants providing mentoring) will communicate and coordinate their efforts to mentor the applicant effectively. | |
| The plan should describe how the sponsor will facilitate the candidate's transition to the next stage of their career, including the search for the K00 mentor, and how the candidate's research and career development progress will be monitored and evaluated throughout the F99 phase, with specific milestones listed. | |
| While candidates are not necessarily expected to already have a first-authored publication from their graduate work, the Candidate Mentoring Plan should describe a plan and timeline for the candidate to achieve meaningful publishable results that will allow them to successfully transition into the K00 phase. Sponsors are encouraged to include the standards and expectations for authorship of publications in the sponsor(s) lab. |
C. Commitment to the Candidate's Research Training Plan Include a description of how the sponsor(s) promote(s) the development of candidate skills in approaches to rigorous experimental design, methods of data collection, data analysis, interpretation, and reporting as well as ethically sound and responsible scientific research.
D. Research Training Environment When describing opportunities for professional development and intellectual interactions, do not just list available opportunities, but indicate which opportunities the candidate will participate in during the research training period and how they will further the candidate's scientific development.
E. Candidate's Potential In this section, the sponsor should address both the candidate's potential for successful completion of the F99 and K00 phases and for becoming an independent investigator.
Clinical Trial Training (If proposed) If the candidate is proposing to gain experience in a clinical trial as part of his or her research training, the sponsor or co-sponsor must include a statement to document leadership of the clinical trial including source of funding, NCT# and appropriate expertise to guide the candidate in any proposed clinical trials research experience. The individual receiving support for the clinical trial (i.e., the sponsor/primary mentor or a co-sponsor) is the responsible individual of record for oversight of the trial though fellows can take part in all components of a clinical trial. Oversight includes (but is not limited to): interacting with relevant Institutional Review Board (IRB) staff; reviewing all informed consent documents; reporting potential serious adverse events; and maintaining responsibility for patient safety. However, the fellow can gain experience in all these components in conjunction with the mentor or individual leading the trial.
| Letters of Support from Collaborators, Contributors, and Consultants | |
| Letter(s) of support should confirm the writer's participation (including frequency of meetings), document the expertise they will contribute, and describe their specific role. | |
| Advisory committee members (if applicable): An advisory committee is optional. The advisory committee for this application may be the same as the Dissertation Committee, but that is not required. If included, signed statements must be provided by each member of the proposed advisory committee. Unless also listed as senior/key personnel, these individuals do not need to provide their biographical sketches. |
Other Plan(s) A Data Management and Sharing Plan is not applicable for this NOFO.
