Core Review Criteria
NSF uses two equally weighted criteria for all proposals:
Intellectual Merit
Definition: The potential to advance knowledge
Evaluation Questions:
- How important is the proposed activity to advancing knowledge and understanding within its own field or across different fields?
- How well-qualified is the proposer (individual or team) to conduct the project?
- To what extent does the proposed activity suggest and explore creative, original, or potentially transformative concepts?
- How well-conceived and organized is the proposed activity?
- Is there sufficient access to resources?
Writing Strategy:
- Lead with the research question and its importance
- Demonstrate deep knowledge of the field
- Articulate the knowledge gap clearly
- Present innovative approach to address the gap
- Show preliminary results or proof-of-concept
- Demonstrate team qualifications
- Present feasible, well-organized plan
Broader Impacts
Definition: The potential to benefit society and contribute to the achievement of specific, desired societal outcomes
Evaluation Questions:
- What is the potential for the proposed activity to:
- Benefit society or advance desired societal outcomes?
- Broaden participation of underrepresented groups?
- Enhance infrastructure for research and education?
- Enhance scientific and technological understanding?
- Foster partnerships between academia, industry, and others?
Critical Point: Broader Impacts are NOT an afterthought. They carry equal weight with Intellectual Merit and must be substantive, specific, and measurable.
Five Pillars of Broader Impacts (address at least one substantively):
-
Advance discovery and understanding while promoting teaching, training, and learning
- Integrate research into courses
- Develop new curriculum materials
- Train undergraduate, graduate, and postdoctoral researchers
- Provide research experiences for students
- Create educational resources (videos, software, databases)
- Offer workshops or training programs
Example: "We will develop a 10-module online course on computational genomics, incorporating data from this project, to be offered to 500+ students annually across 15 partner institutions. Course materials will be open-access and include Jupyter notebooks for hands-on analysis."
-
Broaden participation of underrepresented groups (in STEM)
- Partner with minority-serving institutions (HBCUs, HSIs, TCUs)
- Recruit students from underrepresented groups
- Provide mentoring and support programs
- Address systemic barriers to participation
- Create inclusive research environments
- Engage underrepresented communities in research
Example: "We will establish a summer research program for 8 undergraduates annually from 4 partner HBCUs, providing stipends, housing, and year-round mentoring. Program will include professional development workshops and pathways to graduate school."
-
Enhance infrastructure for research and education
- Develop shared instrumentation or facilities
- Create cyberinfrastructure, software, or databases
- Build collaborative networks
- Establish living stock centers or repositories
- Develop standards or protocols
- Create open-source tools
Example: "We will develop and maintain an open-source software platform for analyzing spatial transcriptomics data, with comprehensive documentation, tutorials, and user support forum. Software will be deposited on GitHub and indexed in bio.tools."
-
Disseminate to enhance scientific and technological understanding
- Public outreach and science communication
- Engagement with K-12 students and teachers
- Museum exhibits or science festivals
- Media engagement (podcasts, videos, articles)
- Policy briefs for decision-makers
- Community science projects
Example: "We will partner with the City Science Museum to create a hands-on exhibit on AI and climate modeling, reaching 50,000+ annual visitors. Exhibit will include interactive simulations and bilingual materials. We will also host quarterly 'Science Saturdays' for local K-12 students."
-
Benefit society
- Economic development and competitiveness
- Health and quality of life improvements
- Environmental sustainability
- National security
- Societal well-being
- Workforce development
Example: "Our drought prediction models will be integrated into USDA's decision support system, benefiting 15,000+ farmers in the Southwest. We will work with extension agents to provide training and accessible interfaces for non-technical users."
Common Broader Impacts Mistakes:
- ❌ Vague statements: "We will train graduate students" (everyone does this)
- ❌ No plan: Aspirational goals without concrete activities
- ❌ No metrics: No way to assess success
- ❌ Tacked on: Not integrated with research plan
- ❌ Unrealistic: Grand claims without resources or expertise
- ✅ Specific and measurable: Clear activities, timelines, and assessment
