Advancing Research Careers (ARC) Predoctoral to Postdoctoral Transition Award to Promote Diversity (F99/K00 - Clinical Trial Not Allowed)

Funding Agency:
National Institutes of Health

The purpose of the Advancing Research Careers (ARC) Predoctoral to Postdoctoral Transition Award to Promote Diversity (F99/K00) program is to support promising, late-stage graduate students from diverse backgrounds, for example those from underrepresented groups (see Notice of NIH’s Interest in Diversity), to transition into and succeed in mentored postdoctoral research positions. It is anticipated that successful completion of this phased award program will position ARC scholars to advance in impactful careers in the biomedical research workforce that typically require postdoctoral training (e.g., academic research and teaching at a range of institution types, industry or government research). This two-phase award will provide support for late-stage graduate students pursuing research related to the mission areas of participating NIH Institutes, Centers, and Offices (ICOs) to facilitate the completion of doctoral dissertation projects and research training (F99 phase), and to transition into and succeed in postdoctoral biomedical research and career development opportunities (K00 phase). ARC F99 fellows/K00 scholars will be part of organized cohorts and will be expected to participate in mentoring, networking, and professional development activities coordinated by ARC Institutionally-Focused Research Education Award to Promote Diversity (PAR-23-221 UE5) recipients. 

This Notice of Funding Opportunity (NOFO) is designed specifically for candidates proposing research that does not involve leading an independent clinical trial, a clinical trial feasibility study, or an ancillary clinical trial. Candidates to this NOFO are permitted to propose research experience in a clinical trial led by a sponsor or co-sponsor.

Eligibility Requirements

F99 Eligibility: Domestic institution/organization types listed above that grant Ph.D. or equivalent research degrees (e.g., Dr.P.H., Sc.D.) are eligible to submit an application. More than one F99 application per institution is allowed.

K00 Eligibility: Domestic institution/organization types listed above, including Federal laboratories, are eligible to submit K00 transition phase applications on behalf of F99 awardees. There is no limit on the number of K00 awardees that an organization may sponsor. Note that if the F99 awardee accepts a postdoctoral position in the NIH intramural research program or another federal agency, the postdoctoral phase (K00) will not be awarded, as federal employees are not eligible for NIH extramural grants. The postdoctoral phase will then be supported directly by the federal agency offering the postdoctoral position, but these postdoctoral scholars are invited to continue to participate in the ARC UE5 mentoring, networking and skills development opportunities.

Multiple PDs/PIs are not allowed.

By the time of award, the candidate 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).

The candidate must have a baccalaureate degree and be currently enrolled as a student in a mentored, biomedical Ph.D. or equivalent research degree program (e.g., Dr.P.H., Sc.D.) at a domestic institution, and should propose research relevant to the mission area of one or more participating NIH Institutes, Centers or Offices.

By the time of award, the candidate must be at 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). 

This F99/K00 award may not be used to support studies leading to the M.D., D.D.S., or other clinical, health-professional degree (e.g., D.C., D.M.D., D.N.P., D.O., D.P.M., D.V.M., N.D., O.D., Au.D.). Students matriculated in a dual-degree clinician scientist training programs (e.g., M.D./Ph.D., D.O./Ph.D., D.D.S./Ph.D., or D.V.M./Ph.D.) are not eligible for the ARC F99/K00 program.

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.

Each candidate may submit one fellowship application at a time: An individual may not have two or more competing NIH individual fellowship applications pending review concurrently. A candidate for an ARC F99/K00 award may not simultaneously submit or have an application pending for any other PHS fellowship award (e.g., F31 or any other PHS award that duplicates any of the provisions of the F99/K00 award).
