The National Science Foundation (NSF) is an independent Federal agency created by Congress in 1950 to “promote the progress of science; [and] to advance the national health, prosperity, and welfare” by supporting research and education in all fields of science and engineering.

From those first days, NSF has had a unique place in the Federal Government: it is responsible for the overall health of science and engineering across all disciplines. In contrast, other Federal agencies support research focused on specific missions such as health or defense. The Foundation also is committed to ensuring the nation’s supply of scientists, engineers, and science and engineering educators.

NSF highly encourages the leadership, partnership, and contributions of individuals who are members of groups underrepresented and/or underserved in STEM education programs and careers in all NSF opportunities. This includes leading and designing STEM research and education proposals for funding; serving as peer reviewers, advisory committee members, and/or committee of visitor members; and serving as NSF leadership, program, and/or administrative staff. NSF strongly promotes and expects that all individuals, including those from groups that are underrepresented and/or underserved in STEM are treated equitably and inclusively in the Foundation’s proposal and award process.

NSF encourages institutions of higher education (IHEs) that enroll, educate, graduate and employ individuals who are members of groups underrepresented and/or underserved in STEM education programs and careers to lead, partner, and contribute to NSF opportunities, including leading and designing STEM research and education proposals for funding.

NSF funds research and education in most fields of science and engineering. It does this through grants and cooperative agreements to approximately 3,000 institutions of higher education, K-12 school systems, businesses, informal science organizations and other research organizations throughout the U.S. The Foundation accounts for about one-fourth of Federal support to academic institutions for basic research.

The Foundation considers proposals[1] submitted by organizations on behalf of individuals or groups for support in most fields of research. Interdisciplinary proposals also are eligible for consideration.

NSF does not normally support technical assistance, pilot plant efforts, research requiring security classification, the development of products for commercial marketing, or market research for a particular project or invention. Biological research on mechanisms of disease in humans, including on the etiology, diagnosis, or treatment of disease or disorder, is normally not supported. Biological research to develop animal models of such conditions, or the development or testing of procedures for their treatment, also are not normally eligible for support. However, research with etiology, diagnosis- or treatment-related goals that advances knowledge in engineering, mathematical, physical, computer, or information sciences is eligible for support. Bioengineering and assistive information technology research to aid persons with disabilities also is eligible. See “Funding” and “Awards” on the NSF website for additional information.

NSF receives more than 43,600 proposals each year for research, education, and training projects, of which approximately 11,300 are funded. In addition, the Foundation receives more than 13,000 applications for graduate and postdoctoral fellowships. One of NSF’s flagship programs, the NSF Graduate Research Fellowship Program (GRFP) helps ensure the vitality and diversity of the scientific and engineering workforce; the program awards about 2,000 fellowships each year. Guidance regarding the GRFP program may be found in the program solicitation, as well as in the GRFP Administrative Guide. The agency operates no laboratories itself but does support National Research Centers, user facilities, certain oceanographic vessels, and Antarctic research stations.

The Foundation also supports cooperative research between IHEs and industry, technical research and development on innovations from the small business community, U.S. participation in international scientific and engineering efforts, and educational activities at every academic level. For example, the Directorate for Technology, Innovation and Partnerships (TIP) collaborates with all the NSF directorates to advance critical and emerging technologies addressing societal and economic challenges and opportunities; accelerate the translation of research results from the lab to market and society; and cultivate new education pathways leading to a diverse skilled technical workforce comprising researchers, practitioners, technicians, and entrepreneurs. TIP accomplishes these objectives by catalyzing strategic partnerships that link IHEs, industry, government, nonprofits, civil society, and communities of practice to cultivate innovation ecosystems throughout the U.S., growing regional economies, creating the jobs of the future, and enhancing the Nation’s long-term competitiveness. Through TIP, America’s Seed Fund powered by NSF - the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs – annually provides approximately 400 startups and small businesses with research and development (R&D) funding to create and develop a prototype or conduct proof-of-concept work, as the foundation for the introduction of innovative new products or services, getting research, much of it NSF-funded, out of the lab and into the market. NSF’s Innovation Corps (I-Corps) program supports NSF-funded researchers in the form of entrepreneurial education, mentoring and funding to accelerate the translation of knowledge derived from fundamental research into emerging products and services. Scientists and engineers can also increase the impact of their NSF-funded research discoveries by developing their technology into a prototype or proof-of-concept through the Partnerships for Innovation (PFI) program, one of the National Science Foundation's technology translation programs. Guidance regarding the NSF’s SBIR, STTR, I-Corps and PFI programs may be found in their respective program solicitations.

NSF is structured much like an IHE with divisions/offices for the various disciplines and fields of science and engineering and for STEM education. NSF also uses a variety of management mechanisms to coordinate research in areas that cross traditional disciplinary boundaries. The Foundation is assisted by advisors from the scientific and engineering communities who serve on formal committees or as ad hoc reviewers of proposals. This advisory system, which focuses on both program directions and specific proposals, involves approximately 50,000 scientists and engineers each year. NSF staff members who are experts in a certain field or area make award recommendations; Principal Investigators (PIs) receive unattributed verbatim copies of peer reviews.

Recipients are wholly responsible for conducting their project activities and preparing the results for publication. Thus, the Foundation does not assume responsibility for such findings or their interpretation.

NSF has Telecommunications Device for the Deaf (TDD) and Federal Information Relay Service (FIRS) capabilities that enable individuals with hearing or speech impairments to communicate with the Foundation about NSF programs, employment, or general information.  TDD may be accessed at (703) 292-5090 and (800) 281-8749, FIRS at (800) 877-8339.
