## 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):

1. **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."

2. **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."

3. **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."

4. **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."

5. **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

**Research.gov** or **Grants.gov**: NSF accepts both

**Process**:
1. Institutional authorization required
2. Upload all required documents
3. Verify PDF compilation
4. Submit (aim for 48 hours early)
5. Receive confirmation and proposal number

### Review Process
