5 Common Grant Writing Mistakes That Get Proposals Rejected

We've read a lot of rejected proposals. These are the five mistakes that show up again and again — and the easy fixes.

1. Talking about your organization before talking about the problem

"Founded in 2009, our organization has served the community for over fifteen years…" Reviewers skim past this. Lead with the people you serve and what's happening to them. Your org's history belongs in the capacity section, not the opening.

2. Goals that aren't measurable

"Improve outcomes for at-risk youth" is not a goal — it's a wish. A real goal names a population, a number, a behavior, and a timeframe. "By June 2027, 80% of the 120 youth enrolled in Program X will demonstrate a one-grade-level gain in reading on the STAR assessment."

3. Budgets that don't match the narrative

If the program description says you'll hire two case managers, the budget needs two case manager lines. Reviewers cross-check. A mismatch reads as carelessness — or worse, as if the budget was copied from another grant.

4. Vague evaluation plans

"We will track outcomes and report to the funder" is not an evaluation plan. Name the tool (pre/post survey, attendance records, third-party assessment), the cadence (quarterly, annually), and who reviews the results. Funders want to know how you will learn from the work, not just how you'll report it.

5. Ignoring the RFP's structure

Most RFPs tell you exactly what sections they want, in what order, with what page limits. A surprising number of proposals reorganize this to match the writer's preferred narrative. Don't. If the RFP says "Section 3: Sustainability (1 page max)," your proposal has a Section 3 titled Sustainability that fits on one page. Reviewers grade against the rubric, and the rubric follows the RFP.

Bonus: AI-generated proposals that name the wrong city

Generic AI tools confidently invent statistics, partner organizations, and even ZIP codes. Every claim in a grant proposal should be traceable to a source you can defend. GrantDraft is built around this — when the model doesn't know a specific fact about your nonprofit, it inserts a "[INSERT: …]" placeholder instead of making one up.
