NSF Grants Guide: National Science Foundation
America's Science Funder
The National Science Foundation is the primary federal funder of basic research across all scientific and engineering disciplines — except biomedical research, which is NIH's territory. NSF funds research at universities, colleges, and non-profit research institutions, and runs major STEM education programs that reach from K-12 through graduate training.
If you're a researcher at a university, an NSF grant is a career-defining achievement. If you're an educator working to improve STEM instruction, NSF has programs designed specifically for you. If you're a small business doing science and technology innovation, NSF's SBIR/STTR program is one of the best in the federal government.
How NSF Is Organized
NSF is organized into directorates, each covering a broad scientific domain. The directorates most relevant for different applicants:
- Biological Sciences (BIO) — molecular biology, genomics, ecology, evolutionary biology
- Computer and Information Science and Engineering (CISE) — computer science, information systems, networking, AI
- Engineering (ENG) — chemical, civil, electrical, mechanical, and biomedical engineering
- Geosciences (GEO) — atmospheric science, ocean science, earth science
- Mathematical and Physical Sciences (MPS) — chemistry, materials science, mathematics, physics, astronomy
- Social, Behavioral and Economic Sciences (SBE) — sociology, psychology, economics, anthropology
- Education and Human Resources (EHR) — STEM education at all levels, workforce development
- Technology, Innovation and Partnerships (TIP) — applied research, NSF SBIR/STTR, innovation translation
NSF Research Grants
The standard NSF research grant is the individual investigator award — a faculty member at a university proposes a research project and is funded to carry it out over three to five years. Awards typically range from $150,000 to $500,000 per year for standard grants; major programs like Major Research Instrumentation and Grants for Large Instrumentation can be substantially larger.
NSF review is conducted by scientific peers — other researchers in your field. The two primary review criteria are intellectual merit (the quality and significance of the proposed research) and broader impacts (the potential benefit to society and the broader scientific community). Both must be addressed explicitly in the proposal.
NSF Education Programs
EHR houses NSF's education portfolio, which includes:
- Discovery Research K-12 (DRK-12) — research and development of STEM education resources, models, and tools for K-12
- Advanced Technological Education (ATE) — improving technician education at community colleges in STEM fields
- INCLUDES — broadening participation in STEM for underrepresented groups
- Improving Undergraduate STEM Education (IUSE) — improving STEM teaching and learning in undergraduate settings
NSF SBIR/STTR
NSF's SBIR program funds small business research and development on topics identified by the companies themselves — unlike most agencies where the topics are set by the agency. NSF SBIR Phase I awards are up to $275,000 for a six-month feasibility study. Phase II awards are up to $1 million over two years for technology development.
NSF is explicit that SBIR proposals must demonstrate both scientific merit and commercial potential. Strong commercial viability framing is essential — reviewers are looking for proposals that will lead to real products and services, not just interesting research.
Tips for NSF Applications
Read the specific solicitation for the program you're applying to, then read NSF's general proposal preparation guidelines. NSF has strict formatting requirements and proposals that don't follow them can be returned without review.
The program officer is your ally. Contact them with a one-paragraph summary of your project idea before investing significant time in a proposal. They'll tell you whether your idea fits the program, which directorate or program to apply to, and what the review panel will be looking for.
