Letter of Support for a Grant: What Partners Should Say and What Funders Require

Checked against official sources · 5 min read

A letter of support for a grant is a short, signed letter in which a partner or public official backs your project and says what it will contribute. Send one only when the funder asks, in the form it asks for: the Office on Violence Against Women (OVW), for example, wants letters on letterhead, signed by an authorized representative, no longer than two pages and dated within 12 months of submission. Specific commitments count for more than praise: NIAID "strongly" advises NIH research applicants against collecting letters "solely as endorsements of your reputation."

Letter of support, letter of commitment or MOU

Funders use these terms differently; OVW's definitions show the distinctions:

Document What it does OVW rule
Memorandum of understanding (MOU) Contains "the terms of a partnership" and describes "the roles of everyone involved" Signed by each partner's authorized representative; up to 5 double-spaced pages
Letter of commitment (LOC) Affirms "the intent to commit specified resources toward a project by one party" Accepted from courts, Tribal governments and Tribal victim service providers unable to submit an MOU, or as a NOFO explains
Letter of support Used when, "for legal reasons, an applicant cannot enter into an MOU" On letterhead, signed by an authorized representative, no longer than two pages

An MOU "is not a substitute for a subaward agreement," OVW adds: if a partner will receive grant funds, plan that agreement separately.

What a strong letter says

OVW says letters of support "must address the same six criteria" as its MOUs, for both the partner writing and the lead applicant. Adapted for any funder, a strong letter:

  • names the partner and gives a brief history of your work together;
  • describes the role the partner will play;
  • states that the partner has reviewed the budget and knows the total you are requesting;
  • matches the project as your narrative and budget describe it;
  • lists the resources the partner will contribute, such as staff time, space or training;
  • says, in NIAID's words, "whether the support is available to anyone on request" or only to you.

Sample wording:

[Partner name] has worked with [your organization] since [year] on [shared work]. For the [project name] project, we will [specific role], providing [resource] from [start date] to [end date]. We have reviewed the project budget and understand that [your organization] is requesting [amount] from [funder].

Ask early and send a writing packet

Offices that write letters for local nonprofits publish their terms:

Office Timing Draft letter
City of Jacksonville, Grants and Contract Compliance Division Request at least 10 business days before you need it "Please include a sample letter of support"
Office of Rep. Adam Smith Two weeks' notice preferred Helpful, but the office rewrites it
Office of Rep. Lois Frankel Form asks for your deadline and expected award date Required on the request form

Jacksonville also wants the grant's name and CFDA/CFSA number, the amount requested and any match, a "brief 1-2 page summary" of your organization and services, and a contact at the funding agency. Build one packet for every writer from a boilerplate library of your organization's facts in three lengths, so each letter repeats accurate figures.

A draft saves time, but each letter should read in the writer's own voice.

Letters from elected officials

An official's letter can show community backing, but it does not decide the award. Rep. Adam Smith's office says the Congressman "cannot promote your office for an award or direct a federal agency to decide a grant in your favor", and addresses letters "to the contact person at the federal agency."

Federal applications: follow the NOFO

In a federal application, the notice of funding opportunity (NOFO) sets which letters you attach. OVW warns that for MOUs, "Missing signatures, however, may result in a reduced score/ranking or removal of the application from consideration."

NIH guidance for research applications adds points to check:

  • NIAID notes that "some NOFOs also limit the number of letters allowed."
  • At NIH, "anyone who writes a letter may not review your application," per NIAID.
  • NIH says its letters of support can be seen by "Anyone with access to view the application," so leave out anything confidential.

A federal project narrative template with work plan and capacity sections puts each partner's role in one place to check letters against.

Foundations and local funders

Some foundations want no extras at first: the Kohlberg Foundation says "Applicants are asked not to send additional supporting materials with the initial letter of inquiry." Attach letters only where the guidelines list them.

When a funder does ask, list each letter, its signer and its date with your other attachments, using a community foundation application template with an attachments checklist. For other funder types, see our kits for US private, community, corporate and government funders.

The Government Grant Kit's US_Government_Project_Narrative_TEMPLATE.docx has work plan and capacity sections for each partner's role and a pre-submission checklist.
