NSF Project Summary Example: The 3 Required Parts, Explained

What NSF says a project summary is

The rule is short enough to quote nearly in full. "Each proposal must contain a summary of the proposed project not more than one page in length." It "consists of an overview, a statement on the intellectual merit of the proposed activity, and a statement on the broader impacts of the proposed activity."

Then two lines that shape how it should read:

• It "should be informative to other persons working in the same or related fields, and, insofar as possible, understandable to a broad audience within the scientific domain."
• "It should not be an abstract of the proposal."

That second line is the one most first drafts break. An abstract compresses the whole proposal. A project summary answers three questions, each under its own heading.

The PAPPG also lists the Project Summary among the sections a full research proposal "must contain". A missing one means the proposal is not accepted or is returned without review.

The 3 required parts, in NSF's words

Overview

Start with the activity, not the background. The rule asks for what "would result if the proposal were funded", then the objectives and the methods. One short paragraph usually does it.

Intellectual Merit

Say what is unknown, and what this project will make known. NSF reviews every proposal on two criteria, Intellectual Merit and Broader Impacts, so the summary is where reviewers first look for both.

Broader Impacts

Name who benefits and how. The PAPPG gives examples of societal outcomes NSF values, including improved STEM education, public engagement with science, a globally competitive STEM workforce, partnerships between academia and industry, and the use of science to inform public policy. It also says the examples are not a complete or required list.

A sample proposal: street-level heat maps from 300 low-cost sensors, under NSF's three headings.

What each paragraph does:

• The Overview opens with the activity and its numbers. "This project will place 300 low-cost temperature sensors on streetlights across three mid-size US cities and publish a street-by-street heat map every hour for two summers." Then who does the work, then the objectives: "to measure how much hotter some blocks run than the airport reading a city uses, and to test which street features (trees, pavement color, building height) explain the difference."
• Intellectual Merit names the gap, then the advance. City heat warnings "rely on one or two weather stations"; satellites show surface heat, not air temperature. Hourly readings at 300 points will separate "the effect of trees from the effect of pavement within the same neighborhood."
• Broader Impacts names three groups who benefit. City health departments get free maps to send cooling-center alerts; "60 community college students will gain paid hardware and data experience"; and the sensor design is published for any city to copy.

The sample is deliberately short: 1,161 characters and 193 words across the three parts. A real summary can use the whole page. The proposal is a sample, not a funded project. Open it as a template: NSF project summary template.

How to write an NSF project summary in 6 steps

1. Write the Project Description first. The summary condenses its aims and its Broader Impacts section; it can't come before them.
2. Write the Overview as "This project will...", then the objectives, then the methods, in that order.
3. Write Intellectual Merit as a gap and an advance. One sentence on what is not known, one or two on what this project will show.
4. Write Broader Impacts as named people and named outcomes. "Students" is vague. "60 community college students, paid" is not.
5. Read it as a scientist from the next field over. NSF asks that it be understandable "insofar as possible" to a broad audience within the scientific domain.
6. Paste it into the three boxes and check the page. Keep each part under its own heading, and make sure the combined text fits on one page.

Text boxes, uploads and the one-page check

Research.gov collects the Project Summary as three separate text boxes, one per part. NSF's own system notice says that since 26 September 2016 its automated check confirms that the combined text of the three boxes, or an uploaded PDF if the summary contains special characters, does not exceed one page, replacing an older check of 4,600 characters. The current PAPPG states the limit as one page and does not give a character count.

If you do upload a PDF, PAPPG 24-1's format rules apply to "all uploaded sections of a proposal":

We checked our template against NSF's rules

We opened our template in the editor on 12 October 2026 and measured it.

So use the One-Pager the way most applicants use a summary draft: to agree the wording with co-investigators, your department and your research office, and to share the project with partners. Paste the final text into the three boxes. Don't upload the designed One-Pager as your Project Summary.

The one-page summaries around a grant

NIH has its own one-page front door, the Specific Aims page, with different rules and a different shape.
