Grant agencies are organizations that provide funding to support various projects, research, and initiatives. These agencies can be government bodies, private foundations, or non-profit organizations. They typically have specific goals and criteria for the types of projects they fund, which can range from scientific research to community development. To apply for funding, individuals or organizations usually submit a proposal outlining their project, budget, and expected outcomes. Successful applicants receive grants, which are financial awards that do not need to be repaid. Examples of grant agencies include the National Institutes of Health and the National Science Foundation.
