How We Make Funding Decisions

Through its merit review process, the U.S. National Science Foundation ensures the proposals it receives are reviewed in a fair, competitive, transparent and in-depth manner.

An outline of NSF's proposal review process is provided on this page. This information is covered in greater detail in NSF's Proposal and Award Policies and Procedures Guide (PAPPG) Chapter III and on the NSF Merit Review site.

How we approach funding

NSF strives to invest in a robust and diverse portfolio of projects that enables breakthroughs across all areas of science and engineering. The foundation uses the following three principles in determining which proposals to fund as a part of its portfolio:

1.

All NSF projects should be of the highest quality and have the potential to advance, if not transform, the frontiers of knowledge.

2.

NSF projects, in the aggregate, should contribute more broadly to achieving societal goals.

3.

Meaningful assessment and evaluation of NSF funded projects should be based on appropriate metrics.

NSF's proposal review process

A brief outline of NSF's proposal review process is provided below. See Chapter III of PAPPG and the NSF Merit Review site for more details.

  1. Once NSF receives a proposal, its program officers conduct a preliminary review to ensure it is complete and conforms to NSF's proposal requirements. If the proposal doesn't meet these requirements, it may be returned without review.
  2. Typically, NSF program officers identify at least three external reviewers, who are experts in the fields represented by the proposal, to review the proposal. The review may be conducted by ad hoc reviewers, a panel of experts, or a combination of both.
  3. Reviewers evaluate the proposal using the two National Science Board-approved merit review criteria: intellectual merit and broader impacts. These criteria cover both the quality of the research and the project's potential impact on society. Program solicitations may also contain additional review criteria.
  4. Input received from reviewers is used by NSF, along with other factors, to make a funding decision. When NSF is developing a portfolio of funded projects, it may consider additional factors such as different approaches to significant research and education questions; potential (with perhaps high risk) for transformational advances in a field; capacity building in a new and promising research area; or achievement of special program objectives.

NSF strives to be able to tell applicants whether their proposals have been declined or recommended for funding within six months.
