Opportunity Information: Apply for PA 21 231
The NICHD Small Research Grant Program (R03 Basic Experimental Studies with Humans Required), funding opportunity number PA-21-231, is a National Institutes of Health (NIH) discretionary grant designed to support small, focused projects that fit within the mission of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). It is specifically intended for basic experimental studies that involve human participants and that meet the NIH definition of a clinical trial because the study prospectively assigns people to one or more conditions. Even though these projects are considered clinical trials under NIH policy, the emphasis here is on basic research, meaning the primary goal is to understand fundamental biological or behavioral mechanisms rather than to test a product, finalize a process, or move a specific application toward implementation.
A key feature of this opportunity is the type of study it is trying to capture, as described in NIH guidance (NOT-OD-18-212) about prospective basic science studies involving human participants. Projects should experimentally manipulate one or more independent variables by assigning participants to different conditions and then measure biomedical or behavioral outcomes in humans. The intent is to generate foundational knowledge about how phenomena work (for example, understanding underlying cognitive, developmental, physiological, or behavioral processes) without being driven by a near-term practical application such as product development, clinical efficacy testing for a specific intervention, or implementation of a particular service model. If a study is primarily aimed at a specific application, process optimization, product testing, or other applied goals, the announcement indicates it should be routed to a different, more appropriate NIH clinical trial required funding opportunity.
The mechanism is an R03 small grant, which generally signals a smaller scope project and a more limited budget compared with larger NIH mechanisms, and the listed award ceiling in the source information is $50,000. The program falls under the Health, Income Security and Social Services funding activity category and is associated with CFDA number 93.865. The original closing date provided in the source data is 2025-01-07, and the opportunity record shows a creation date of 2021-04-21.
Eligibility is broad and spans many types of organizations. It includes various levels of U.S. government entities (state, county, city or township, and special district governments), independent school districts, and public housing authorities/Indian housing authorities. Higher education institutions are eligible, including public and state-controlled universities and colleges as well as private institutions of higher education. The opportunity also allows nonprofit organizations both with and without 501(c)(3) status, and it includes for-profit organizations (other than small businesses) as well as small businesses. Tribal eligibility is explicitly included, covering federally recognized Native American tribal governments and other Native American tribal organizations, plus Indian/Native American tribal governments that are not federally recognized. In addition, the announcement highlights other eligible applicant groups such as Alaska Native and Native Hawaiian Serving Institutions, Asian American Native American Pacific Islander Serving Institutions (AANAPISISs), Hispanic-serving Institutions, Historically Black Colleges and Universities (HBCUs), Tribally Controlled Colleges and Universities (TCCUs), faith-based or community-based organizations, eligible federal agencies, regional organizations, non-U.S. (foreign) organizations, and U.S. territories or possessions.
In practical terms, this grant opportunity is best suited for investigators who want to run a tightly scoped, experimentally controlled human study that advances basic science questions relevant to NICHD priorities, and who can clearly justify why the work qualifies as both a clinical trial (because of prospective assignment) and basic research (because it is mechanism-focused rather than application-driven).Apply for PA 21 231

FAQs: NICHD Small Research Grant Program (R03 Basic Experimental Studies with Humans Required) - PA-21-231
What is this funding opportunity?
This opportunity is the NICHD Small Research Grant Program (R03 Basic Experimental Studies with Humans Required), funding opportunity number PA-21-231. It is a discretionary grant from the National Institutes of Health (NIH) intended to support small, focused research projects that align with the mission of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).
What type of research is this announcement designed to support?
It supports basic experimental studies with humans that meet the NIH definition of a clinical trial. The supported projects should be basic research focused on understanding fundamental biological or behavioral mechanisms (for example, cognitive, developmental, physiological, or behavioral processes), rather than research aimed at near-term practical applications.
Why does NIH consider these projects to be clinical trials?
Under NIH policy, these projects are considered clinical trials because they prospectively assign human participants to one or more conditions (that is, participants are assigned to different conditions as part of the study design) and then measure biomedical or behavioral outcomes.
How is "basic experimental studies with humans" described in the opportunity?

This framing aligns with NIH guidance about prospective basic science studies involving human participants (referenced as NOT-OD-18-212 in the opportunity description).
What is the primary goal of the research funded by this announcement?

What kinds of projects are likely NOT a fit for this specific announcement?
Projects that are primarily application-driven are indicated as better suited to other NIH clinical trial required funding opportunities. Examples described include studies mainly aimed at product development, clinical efficacy testing for a specific intervention, process optimization, finalizing a process, or moving a specific application toward implementation.
What grant mechanism is used for this program?
The program uses the NIH R03 mechanism, which is commonly used for small, focused projects with a more limited scope and budget compared with larger NIH award mechanisms.
