Securing a grant is a major achievement. But it's only the beginning. Funders want to know if their investment made a difference. You might be wondering: what is a grant evaluation letter? This essential document not only highlights your program's outcomes but also builds trust and lays the foundation for future funding.
At ERI Grants, we believe a well-written grant evaluation letter can be just as powerful as the grant proposal itself. Let's explore why this matters, what to include, and how our team can help your organization succeed.
What is a Grant Evaluation Letter?
A grant evaluation letter is a concise yet powerful document submitted to a funder that summarizes the effectiveness, outcomes, and fiscal responsibility of a grant-funded program. It’s typically created at the end of a grant period and offers a high-level snapshot of what was achieved, how resources were used, and what the organization learned along the way.
Think of it as the “report card” for your grant. While it doesn’t go into the granular detail of a full final report, it delivers the most critical insights in a straightforward format. This makes it easier for funders to quickly understand the return on their investment and the impact their funding made in the community.
These letters serve multiple functions:
Assess return on investment: Funders need to know their dollars made a difference.
Demonstrate program integrity: Showcasing measurable impact and alignment with the original proposal reassures funders.
Strengthen funder relationships: A well-crafted letter shows professionalism, appreciation, and a commitment to transparency.
Open doors to future opportunities: Strong evaluation letters can lead to repeat funding or referrals to other grantmakers.
For organizations like school districts, charter schools, community nonprofits, or hospitals, submitting a thoughtful grant evaluation letter demonstrates more than just compliance—it reinforces trust and commitment to outcomes. It’s a chance to close the funding loop with integrity while laying the groundwork for future collaboration.
Why Grant Evaluation Letters Matter for Nonprofits
A grant evaluation letter does more than close the loop on a funding cycle. It sets the stage for your next opportunity. Here's why this matters:
Builds Trust
Funders appreciate transparency. When you provide clear, honest, and thoughtful evaluations, they’re more likely to fund your work again. A thorough evaluation shows you take stewardship seriously and value the relationship beyond the check. It’s a way of saying, “We respect the trust you placed in us.”
Documents Results
Evaluation letters capture what worked, what didn’t, and what can be improved. This reflection helps shape future programming. It also creates a record of your progress that can be shared with leadership, boards, and community members, reinforcing your mission and accomplishments.
Improves Funding Opportunities
Well-documented impact boosts your chances of securing renewal grants or new funding from other sources. Funders talk to each other. A strong evaluation letter can open the door to new relationships simply by showing that your organization is effective, responsible, and results-driven.
Supports Continuous Improvement
Evaluation is not just about accountability—it’s about growth. Lessons learned help you build better, more effective programs moving forward. It encourages a culture of learning where staff are motivated to adapt and innovate, knowing that funders value honesty and improvement over perfection.
Strengthens Community Credibility
Being able to show that your programs are achieving measurable results helps build credibility within your community. Whether you’re serving at-risk youth, low-income individuals, or veterans, your grant evaluation letter becomes a public-facing proof point of your impact.
At ERI, we work with clients to turn evaluations into strategic tools that support long-term sustainability. We don’t just help you write the letter—we help you understand the story behind the data, and how to use that story to grow your programs and partnerships.
What Is a Grant Evaluation Letter? Key Components for a Strong Submission
Summary of the Funded Program
Start with a clear, concise summary of your program:
What was the program’s purpose?
Who did it serve?
What activities were implemented?
Data and Outcomes
Show the results—both numbers and stories:
How many people were served?
What measurable outcomes were achieved?
What impact did the program have?
Use data to back up your claims, and include personal stories or testimonials to bring those numbers to life.
Budget Overview
Funders want to know how their dollars were used:
Were funds spent according to the proposed budget?
Were there any unexpected costs or savings?
Keep it simple. Include categories like staffing, supplies, or technology, and explain any changes.
Alignment With Grant Goals
Demonstrate how your program stayed focused on the funder’s objectives:
How did the program address the needs identified in the original proposal?
Were grant outcomes achieved?
This is your chance to show you kept your promises.
Lessons Learned
Be honest about what you learned:
What challenges did you face?
What adjustments were made?
What would you do differently next time?
Funders respect organizations that are reflective and proactive.

Common Mistakes to Avoid When Writing: What Is a Grant Evaluation Letter and How to Get It Right
Being Too Vague
Avoid generalities like “The program was successful.” Instead, provide concrete evidence of results.
Failing to Connect Outcomes to Goals
If your original grant application outlined specific goals, your evaluation must report on progress toward those exact goals.
Omitting Budget Details
Funders expect transparency in how funds were spent. Even if everything went to plan, they want to see it documented.
Ignoring Areas for Improvement
Programs are rarely perfect. Show that you recognize challenges and are committed to continuous improvement.
When and How to Submit a Grant Evaluation Letter
Each funder has its own timeline and requirements. Always follow their instructions carefully.
Timing
Evaluation letters are typically due at the end of the grant period. However, some funders may request mid-year updates as well.
Format
Some funders request electronic submissions via portals, while others prefer PDF uploads or email.
Communication
When in doubt, contact the funder to clarify expectations. Open communication can prevent missteps.
