Research Supplements to Promote Diversity in Health-Related Research (PA-23-189)
NIH diversity supplements (PA-23-189) add funding to an existing NIH grant to support a trainee from an underrepresented group — including undergraduates, post-baccs, predoctoral, and postdoctoral candidates. The KEY point for an undergrad: YOU do not apply directly; your faculty mentor (the parent-grant PI) submits on your behalf. Applications are rolling. The parent grant must have enough time remaining (e.g., ~1 year for post-bacc, ~2 years for predoctoral).

NIH Research Supplements to Promote Diversity (PA-23-189)
This is arguably the most accessible federal research funding for an undergraduate in cancer research — because it does not require you to win a national competition. Instead, an existing NIH grant gets supplemental money to support you as a mentored trainee from an underrepresented background.
How it actually works (read this first)
You, the trainee, do not submit the application. The Principal Investigator of an active NIH research grant (your faculty mentor) requests an administrative supplement to add you to their funded project (PA-23-189). This is why building a relationship with a funded mentor matters more than any single deadline.
Who is eligible (candidate)
Candidates from groups underrepresented in biomedical/behavioral research — including by race/ethnicity, disability, or disadvantaged background — across all stages:
- High school and undergraduate students (summer and/or academic year).
- Post-baccalaureate candidates and master's-degree holders.
- Predoctoral students.
- Postdoctoral and investigator-level candidates.
Eligibility is established by a signed statement from an institutional official, including citizenship documentation (PA-23-189).
The parent-grant constraint
The mentor's grant must have enough time left:
- ~1 year remaining for post-baccalaureate candidates or master's holders.
- ~2 years remaining for predoctoral candidates.
- ~18 months for postdoctoral/investigator-level candidates.
