TL;DR
NSF Broader Impacts activities should be specific (who, what, how many), measurable (with evaluation), connected to your research, and sustainable. Common categories include broadening participation in STEM, education integration, public engagement, infrastructure development, and societal benefit. Avoid vague statements like "I will mentor diverse students" without specifics. GrantCopilot provides templates that prompt you to address each element reviewers evaluate.
Broader Impacts is one of NSF's two merit review criteria, carrying equal weight with Intellectual Merit. Yet many researchers treat it as an afterthought — a paragraph about mentoring students or giving public talks, added the night before the deadline. Reviewers notice, and it costs proposals points.
A strong Broader Impacts plan is specific, measurable, connected to your research, and realistic about what you can accomplish. This guide covers what NSF means by Broader Impacts, what reviewers look for, and how to write a plan that strengthens rather than weakens your proposal.
What NSF Means by Broader Impacts
NSF's definition is intentionally broad — Broader Impacts encompasses the potential to benefit society and contribute to desired societal outcomes. The PAPPG lists several categories:
- Full participation of women, persons with disabilities, and underrepresented minorities in STEM
- Improved STEM education and educator development at any level
- Increased public scientific literacy and public engagement with science and technology
- Improved well-being of individuals in society
- Development of a diverse, globally competitive STEM workforce
- Increased partnerships between academia, industry, and others
- Improved national security
- Increased economic competitiveness of the United States
- Enhanced infrastructure for research and education
What Reviewers Actually Evaluate
While the categories are broad, reviewers consistently look for specific qualities in Broader Impacts plans:
- Specificity: Who exactly benefits? How many people? Through what activities?
- Credibility: Do you have the capacity, partnerships, and resources to do what you propose?
- Connection to research: How does your research enable or enrich these activities?
- Evaluation: How will you know if your activities worked? What metrics will you track?
- Sustainability: Will the impact continue after the grant ends?
- Significance: Does the scale of impact match the scale of the award?
Effective Broader Impacts Strategies
The strongest Broader Impacts plans use the research itself as the foundation for outreach and education. Here are concrete approaches that work:
Undergraduate Research Involvement
Involving undergraduates is one of the most credible Broader Impacts activities because you directly control it:
- Specify how many undergraduates per year and what they will do
- Describe recruitment strategies to reach underrepresented students
- Explain mentoring structures and how students progress through the program
- Document outcomes: presentations, publications, graduate school placement
- Consider REU supplements or connections to existing REU programs
K-12 Partnerships
K-12 outreach shows impact beyond the university, but only if it is specific:
- Name the partner schools or programs you will work with
- Describe specific activities: classroom visits, curriculum modules, teacher workshops
- Explain how your research content translates into age-appropriate learning
- Include letters of collaboration from partner schools or organizations
- Address logistics: who delivers the activities, how often, and how you will evaluate learning
Public Engagement and Communication
Public-facing activities work best when they are structured and measurable:
- Museum exhibits, public lectures, or science festival demonstrations with attendance targets
- Open-access datasets, tools, or software that non-specialists can use
- Community science projects that involve the public in data collection
- Media engagement or science communication training for students in the lab
- Partnerships with journalism programs or science communication organizations
Broadening Participation in STEM
NSF places high value on activities that bring underrepresented groups into STEM fields:
- Partner with existing programs (e.g., McNair Scholars, LSAMP, TRIO) rather than creating new infrastructure
- Design bridge programs, summer research experiences, or mentoring networks for specific populations
- Recruit from minority-serving institutions, community colleges, or tribal colleges
- Track outcomes: retention rates, degree completion, career placement
- Address systemic barriers, not just individual access — mentoring alone is not enough
Common Broader Impacts Mistakes
These patterns consistently weaken proposals:
- Vague language: "We will engage diverse communities" says nothing without specifics
- Listing activities without evaluation: if you cannot measure it, reviewers doubt it will happen
- Disconnected from research: a robotics workshop is not Broader Impacts for a geology proposal unless you explain the connection
- Overpromising: claiming you will reach 10,000 students with no infrastructure is not credible
- Generic mentoring: "I will mentor graduate students" is part of your job, not a Broader Impact
- No partners: activities requiring community or school partnerships need letters confirming the relationship
- Last-minute additions: a single paragraph shows minimal effort and reviewers score accordingly
How to Structure Your Broader Impacts Section
A well-organized Broader Impacts section covers these elements:
- Clear statement of the societal problem or need your activities address
- Description of each activity with target audience, frequency, and scale
- Explanation of how activities connect to and leverage your research
- Qualifications and partnerships that establish credibility
- Evaluation plan with specific metrics and data collection approach
- Timeline showing when activities begin and how they scale over the award period
- Sustainability plan for continuing impact after the grant ends
How GrantCopilot Helps with Broader Impacts
GrantCopilot provides structured support for planning and writing Broader Impacts:
- Templates with prompts for each element reviewers evaluate: specificity, credibility, connection, evaluation
- Directorate-specific guidance on Broader Impacts expectations and common activities in your field
- Checklists ensuring your plan addresses NSF merit review criteria throughout the proposal
- Examples of language patterns that communicate concrete plans rather than vague intentions
- Integration with the full proposal structure so Broader Impacts appears in the Project Summary, Project Description, and Budget Justification
Broader Impacts is not a box to check — it is half of how NSF evaluates your proposal. The researchers who write strong Broader Impacts plans treat them with the same rigor they apply to their research design: specific activities, clear metrics, credible partnerships, and honest evaluation. Start with what your research makes possible, build outward to audiences who benefit, and document how you will know it worked.
GrantCopilot's NSF templates help you structure Broader Impacts plans that reviewers take seriously, with prompts that move you past vague statements toward specific, evaluable activities.
