National Science Foundation: An Overview Summary

Core Content

The National Science Foundation (NSF) is an independent federal agency established by Congress through the National Science Foundation Act of 1950. Its mission is to "promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense; and for other purposes." The NSF supports basic research and education in non-medical sciences and engineering, and is a major source of federal funding for U.S. university research, especially in social sciences, mathematics, and computer science. It also plays a significant role in STEM education programs and student aid.

Main Viewpoints

• Autonomy vs. Accountability: The NSF's independent status, characterized by its freestanding position in the executive branch and its 24-member National Science Board (NSB), provides it with greater autonomy than many other federal agencies. However, this independence can be seen as conflicting with the need for public accountability, particularly in how funds are allocated and managed.
• Leadership Structure: The NSF is governed by the NSF director and the NSB. The director oversees daily operations, while the NSB sets policies, approves budgets, and serves as an advisory body to Congress and the President.
• Workforce Composition: In FY2020, the NSF had over 2,000 employees, including 175 temporary "rotators" from the research community. Rotators can be either under the Intergovernmental Personnel Act (IPA) or the Visiting Scientist, Engineer, and Educator (VSEE) program.
• Funding Allocation: The NSF is the second-largest source of federal funding for basic research after the Department of Health and Human Services. In FY2020, it distributed 74% of its funds through grants, 21% through cooperative agreements, and 5% through contracts. Approximately 80% of its funding goes to colleges, universities, and academic consortia.
• Competitive Review Process: The NSF funds research through a rigorous, merit-based process involving three phases and multiple layers of evaluation, including peer review, program officer review, and final business and policy assessments. In FY2020, the success rate for competitively reviewed proposals was 28%.

Key Information

Funding Profile

• FY2021 Appropriations: $8.49 billion, with 81.4% allocated to Research and Related Activities (RRA), 11.4% to Education and Human Resources (EHR), and 2.8% to Major Research Equipment and Facilities Construction (MREFC).
• Funding Trends: After remaining relatively flat from FY2010 to FY2019, NSF funding saw slight increases in FY2020 and FY2021, adjusted for inflation.

Directorates and Offices

The NSF is organized into seven directorates, each focusing on a specific academic discipline, and two offices that manage agency-wide programs:

• Directorates:

  • Mathematical and Physical Sciences (MPS): Largest directorate with $1.491 billion in FY2019 funding.
  • Biological Sciences (BIO): Focuses on understanding life and biological systems, with $784 million in FY2019 funding.
  • Computer and Information Science and Engineering (CISE): Promotes interdisciplinary collaboration and supports AI research, with $985 million in FY2019 funding.
  • Education and Human Resources (EHR): Aims to improve STEM education, with $935 million in FY2019 funding.
  • Engineering (ENG): Invests in engineering research and innovation, with $991 million in FY2019 funding.
  • Geosciences (GEO): Supports research in atmospheric, earth, ocean, and polar sciences, with $970 million in FY2019 funding.
  • Social, Behavioral, and Economic Sciences (SBE): Focuses on human behavior and social systems, with $271 million in FY2019 funding.

• Offices:

  • Office of International Science and Engineering (OISE): Oversees international science and engineering initiatives.
  • Office of Integrative Activities (OIA): Coordinates cross-disciplinary and integrative research initiatives.

Selected Integrative Activities

• Artificial Intelligence (AI): The NSF has been a key player in AI research, with a focus on fundamental research, workforce development, and public-private partnerships. The National Artificial Intelligence Act of 2020 allocated $868 million in FY2021 for AI research, nearly double the FY2019 funding. The NSF also co-chairs an interagency committee on AI and is working on establishing a National AI Research Resource.
• Big Ideas: These are bold, cross-disciplinary research initiatives aimed at breaking down traditional scientific silos. Examples include:
  • AI and Big Data
  • Quantum Leap
  • Convergence Accelerator
  • Resilient and Sustainable Infrastructure
  • Understanding the Rules of Life
  • The Next Generation of Workforce

Conclusion

The NSF plays a critical role in advancing U.S. scientific research and education. Its independent status allows for greater autonomy in decision-making, but also raises questions about accountability. The agency's structure, funding mechanisms, and integrative initiatives reflect its commitment to fostering innovation and interdisciplinary research across a wide range of scientific and engineering fields.
