What to do, step by step
Ask what the letter needs to cover
Find out who will read it, the deadline, and anything the funder, agency or committee wants letters to address. Many grant programs list exactly what support letters should include.
Introduce yourself
Give your name, title and organization so the reader understands why your support carries weight.
Explain your connection
Say how you know the person or project, how long, and in what capacity.
Give specific reasons
Describe results, qualities or needs you have seen first-hand. Concrete examples and numbers are more persuasive than general praise.
State any commitment and sign
If you or your organization will contribute something, say exactly what. Sign the letter, ideally on letterhead, and send it the way the applicant asks.
What if your letter doesn't seem to make a difference?
A letter of support is one piece of a larger application, so it rarely decides the outcome on its own. Funders and agencies weigh it alongside budgets, plans, eligibility rules and many other applicants.
If the application is turned down, the applicant can often ask for feedback and apply again. A letter that is specific, up to date and tied to the reader's criteria is more useful the next time around, so keep your draft.
If you're asked to write again, update the details: new results, new numbers and any change in your relationship. A recycled letter with old dates can undermine an otherwise strong application.

Re: Letter of support for the Riverside Youth Mentoring Program
Dear Grant Review Committee,
I am pleased to write this letter in support of the Riverside Youth Mentoring Program and its application for the 2027 Fairmont Community Foundation Youth Services Grant.
As principal of Lincoln Elementary for the past seven years, I have worked closely with Riverside since it began mentoring our students in 2021. Its volunteers are on our campus three afternoons a week.
Of the 40 students paired with a Riverside mentor last year, 34 improved their attendance, and several teachers have told me the change in confidence is remarkable. The program reaches children who would otherwise go home to an empty house, and it has a waiting list of more than 25 families at our school alone.
If the grant is awarded, Lincoln Elementary will continue to provide classroom space and a staff liaison at no cost, and we will help identify students who would benefit most.
For these reasons, I fully support the Riverside Youth Mentoring Program and encourage you to give this request your favorable consideration. Please feel free to contact me at (555) 448-2017 · hpark@lincoln-elementary.example.org if I can provide any further information.
Sincerely,
Dr. Helen Park
Principal, Lincoln Elementary School
Frequently asked questions
What is a letter of support?
It is a letter from a person or organization stating that they back someone's application, project or request, and explaining why. Letters of support are common in grant applications, immigration cases, community projects, zoning requests and personal applications such as housing or school admission.
What's the difference between a letter of support and a letter of recommendation?
A letter of recommendation usually evaluates a person's skills for a job or school place. A letter of support backs a specific application or project, and may come from a partner organization, community leader or friend. Support letters often include a commitment, such as space, funding or referrals.
How long should a letter of support be?
Usually one page. Readers often review many letters, so a focused letter that explains who you are, your connection and two or three specific reasons is more effective than a long one. Check whether the funder or agency sets a page limit.
Should a letter of support be on letterhead?
If you're writing on behalf of an organization, yes; letterhead shows the letter comes from the organization and not just an individual. If you're writing personally, a plain letter with your full name, address and contact details is fine.
Can the applicant draft the letter for me to sign?
Some applicants provide a draft to save time, especially for grants. If you use one, edit it so it's accurate and sounds like you, and only sign what you believe is true. Reviewers can often tell when every support letter has the same wording.
