Diversity Supplement and Re-Entry Program Guidelines

Advancing Diversity in Aging Research

NIA's supplement awards program supports emerging researchers with a mentor-directed opportunity that fosters and expands the research capabilities, knowledge, and skills of trainee-candidates in diverse aging research areas. NIA's Diversity Supplement and Small Business Diversity Supplement programs support the development of eligible trainee-candidates who seek independent and productive careers in research on aging and enhance diversity in the biomedical workforce. The Re-entry and Re-Integration Supplement program supports eligible individuals in reentering an active research career after life events have placed their research careers on hold.

Overview of NIA Supplement Programs

NIA Diversity Supplements at a Glance
Topic Description

Submission Deadlines

NIA accepts applications on a rolling basis and reviews applications in a monthly cycle. Applications will be reviewed within 2-3 months of receipt. Applications seeking consideration before September 30 must be received by May 1.

Clinical Trial

Independent or ancillary clinical trials are not allowed. Applicants are permitted to propose research experiences and activities in clinical trials led by a mentor or co-mentor. Visit this link to determine whether you are doing a clinical trial.

Parent Grant

Eligible parent grants are comprehensively listed in PA-23-189 and PA-21-345. The parent grant must have at least two years of active status left at the time of supplement application unless the performance period of the grant is less than two years. Supplements are not considered for grants in a no-cost extension.

Program Director/Principal Investigator (PD/PI)

Must be a PD/PI on an active parent grant. For Multiple Principal Investigator (MPI) parent grants, the Contact PI should submit the application through his or her institution even though work on the supplement may be conducted at another institution. For multi-component parent grants, the overall Contact PI should submit the application from his/her institution on behalf of project/core PIs.


Consistent with the Notice of NIH’s Interest in Diversity (NOT-OD-20-031), eligibility for this program includes candidates from groups that are underrepresented in the biomedical, clinical, behavioral and social sciences, such as, individuals from underrepresented racial/ethnic groups, with a disability, or from disadvantaged backgrounds.

NIA accepts diversity supplement applications to support high-school students, undergraduates, postbaccalaureate, Master’s, PhD, postdoctoral, and eligible new investigator candidates who are developing their independent research careers. Established investigators who are or become disabled are eligible to apply for a diversity supplement to support reasonable accommodation as described in the in PA-23-189 and PA-21-345. Candidates must be U.S. citizens or permanent residents.

Award Budget

Varies based on career level of the candidate

Award Duration

2 years or less

In alignment with the respective notices of funding opportunity PA-23-189PA-21-345, and NOT-OD-21-134, NIA’s diversity and re-entry and re-integration programs are not intended to provide additional or alternative means for supporting individuals who are receiving funding from other Public Health Service (PHS) sources. Removing an individual from current PHS funding does not confer eligibility for support. The only exception is where current funding is term-limited and does not exceed 6 months in its entirety. Details specifying current PHS funding must be included, e.g., in the candidate eligibility statement, at the time of submission of the supplement application. Short-term support from the parent PHS grant is allowable.

Guidelines for Submission

Applications must be submitted electronically as described in PA-23-189, PA-21-345, and NOT-OD-21-134.

  • A parent grant may support more than one individual on a diversity supplement. A separate application is required for each candidate and each application will be evaluated independently.

Applicants are strongly encouraged to inform their program officer and to copy the supplement program contact ( prior to and immediately following submission.

Clinical Trials Not Allowed. NIA diversity and re-entry and re-integration supplements are not designed for applicants proposing an independent or ancillary clinical trial. Applicants to this Notice of Funding Opportunity (NOFO) are permitted to propose research experiences and activities in clinical trials led by a mentor or co-mentor. For more information to determine whether a project meets the NIH definition of a behavioral or clinical trial, please review this resource: Need help determining whether you are doing a clinical trial?

Eligible Activities. Diversity Supplement applications are accepted under R00, R03, R21/R33, and R15 awards for support of high-school students, undergraduates, postbaccalaureate or terminal masters' candidates only. For all other activity codes, NIA accepts diversity supplement applications to support high-school students, undergraduates, postbaccalaureate, master’s, Ph.D., postdoctoral, early-stage, and new investigator candidates. Career development awards and training grants are not eligible. All research project activities are eligible to apply for a disability supplement. For eligible parent grants for re-entry and re-integration supplements, please refer to NOT-OD-21-134.

Candidate Eligibility. NIA follows NIH guidelines as articulated in the diversity (PA-23-189 and PA-21-345) and the re-entry and re-integration (NOT-OD-21-134) announcements. Diversity supplements are also available to PI(s) of research grants who are or become disabled and need additional support to accommodate their disability to continue to work on the research project.

  • A candidate who is currently receiving support from another PHS funding source (including the parent grant) is not eligible to receive overlapping supplement funding. Investigators seeking supplement support should inquire with the supplement program contact ( about eligibility based on their funding status.
  • Candidates who have had support on a National Research Service Award (NRSA) training grant or a previous diversity or disability supplement are eligible for support once they have completed their appointment. Candidates for a second diversity supplement award should outline clearly in their biographical sketch their accomplishments during the prior supplement period and the reason(s) for a second supplement request at this later stage in their training.
  • Current and former PDs/PIs who have been the recipients of the following NIH grants are not eligible to be named as a candidate for a diversity supplement unless they are or become disabled: R01 and R01-equivalent grants, P01, P50 (including subproject/core leads), K01, K07, K08, K22, K23, K25, K76, K99/R00. R01-equivalent grants are defined as activity codes DP1, DP2, DP5, R37, R56, RF1, RL1, U01 and R35.
  • Starting in FY22, candidates receiving pilot support from an NIA-funded parent grant who are receiving a salary from pilot funds may be considered for a Diversity Supplement. If approved, funding will begin only when pilot funding ends. If a candidate is not receiving a salary from pilot funds, a Diversity Supplement may be submitted for non-duplicative costs. If approved, funding may be concurrent with pilot funds.

Period of Support. Generally, a minimum of two years should remain on the project period of the grant. NIA awards diversity and re-entry and re-integration supplements for 2 years or less. In all cases, the research/training proposed should be appropriate for the time requested, with stated milestones and a mentoring and career development plan. For grants with performance periods of less than two years, and for requests for a single year award, the proposed supplement should justify the need for a strategic training activity appropriate for the shortened performance period. Supplement awards are not provided to grants in a no-cost extension.
