NIOSH Exploratory/Developmental Grant Program (R21)

The NIOSH Exploratory and Developmental Grant Program is administered by the Centers for Disease Control and Prevention within the U.S. Department of Health and Human Services. Through its National Institute for Occupational Safety and Health division, the agency supports research aimed at improving workplace safety and reducing occupational illness and injury across the United States. This funding opportunity is categorized as a discretionary federal grant and is listed under the Occupational Safety and Health Program. The program is part of a broader federal effort to generate scientific knowledge that can inform policy, workplace practices, and preventive interventions that protect workers in a wide range of industries. The primary purpose of this grant program is to advance understanding of occupational diseases and injuries through exploratory and developmental research. Applicants are expected to focus on identifying risks and conditions that contribute to workplace health issues, developing strategies to mitigate or eliminate these risks, and translating scientific discoveries into practical prevention tools and methods. The program specifically encourages innovative concepts, new model systems, and the development of tools or technologies that could significantly improve occupational health outcomes. Emphasis is placed on early stage or high risk research ideas that may not yet be fully developed but show strong potential for impact. Funding under this opportunity supports projects that clearly define a specific occupational health burden and propose research activities that directly address that burden. Applicants must demonstrate how their proposed work will generate outputs that contribute to reducing work related hazards and improving worker safety. The scope of allowable activities includes research design, data collection, development of interventions, and evaluation of potential prevention strategies. Projects are expected to articulate both short term outputs and long term outcomes, including how findings may be translated into practice or policy. The program does not require cost sharing or matching funds, which lowers barriers for a wide range of applicants. Eligible applicants include a broad spectrum of entity types such as small businesses, higher education institutions, nonprofit organizations with or without 501c3 status, and various levels of government including state, county, and tribal entities. However, eligibility is restricted to domestic entities within the United States. Foreign organizations and non U.S. components of U.S. institutions are not permitted to apply, and foreign components are explicitly disallowed under federal grant policy. The application process is expected to follow standard federal submission procedures, with all applications submitted electronically through Grants.gov by the specified deadline. Applicants must provide a detailed research proposal that includes a clear description of the occupational health issue being addressed, the methodology for conducting the research, and the anticipated outputs and impacts. The application must also outline how the proposed activities align with NIOSH priorities and demonstrate feasibility within the project period. Submissions must be completed by the stated deadline time of 1159 pm local time of the applicant organization. The timeline for this opportunity indicates that it is currently in a forecast stage, with an estimated posting date in mid December 2026 and an application due date in mid February 2027. Awards are anticipated to be announced in early August 2027, with project start dates beginning in September 2027. Approximately ten awards are expected to be issued, with total program funding estimated at three million dollars. Individual awards may reach up to three hundred thousand dollars, supporting short term exploratory projects. The opportunity is expected to follow standard due dates for future cycles, suggesting a recurring structure aligned with federal research grant schedules.
