Whether you are first getting started with federal grants, or you have a few federal grant submissions (and maybe even awards!) under your belt, you may feel the pressure of the highly competitive process. The dollars at stake are huge and so are the impacts on your organization.

 

As we’ve been designing Grant Writing Boot Camp in collaboration with MyFedTrainer.com, I put together a Top 10 list about mistakes we see and hear about with federal grant applications. They aren’t in sequential order the way we might expect on a late-night tv show, as the likelihood of the mistake to impact an organization depends on countless factors.

 

The Top 10 Federal Grant Application Mistakes

 

Mistake #1: Saving Federal Grant Portal Registrations for the Last Minute

Federal grant portals like Grants.gov, SAM.gov, and agency-specific systems require advance registration that can take days or weeks to process. Starting this step late can disqualify your application before you write a single word. Build portal registration checks into your grant calendar well ahead of deadlines.

 

Mistake #2: Focusing Only on Currently Open Opportunities

Strong federal grant seekers look ahead. Forecasted and anticipated opportunities — listed on agency websites before they formally open — give you critical lead time to plan your program design, engage partners, and build your narrative before the clock starts.

 

Mistake #3: Not Engaging Collaborative Partners Early

Letters of commitment and authentic partnership descriptions cannot be manufactured at the last minute. Bring your collaborative partners into proposal design and drafting discussions early — their input strengthens your application and their buy-in shows reviewers that the collaboration is real.

 

Mistake #4: Using Acronyms Without Spelling Them Out

As covered in our post on what not to say in grant applications, acronyms throughout your proposal, work plan, and logic model create confusion for reviewers who may not share your field’s vocabulary. Always spell out acronyms on first use — and again later in longer documents.

 

Mistake #5: Not Consistently or Completely Citing Your Sources

Federal reviewers are trained to look for evidence-based practices. Unsupported claims — or sources cited inconsistently — undermine your credibility. Whether using narrative citations or footnotes, cite every data point, statistic, and research reference you include.

 

Mistake #6: Not Including SMART Objectives

Federal grant applications almost always require objectives, and reviewers expect them to be Specific, Measurable, Achievable, Relevant, and Time-bound. Vague or unmeasurable objectives are one of the fastest ways to lose points in a scored review. Download our free SMART Objectives Toolkit to make sure yours are reviewer-ready.

 

Mistake #7: Making Reviewers Solve for Variables in Your Budget Justification

Every line item in your budget should be explained in enough detail that a reviewer can verify the math without having to make assumptions. Show your calculations explicitly — number of participants × cost per participant × number of months, for example. Our free Grant Budget Storytelling Guide can help you present your budget clearly and compellingly.

 

Mistake #8: Having the Same Team That Wrote the Application Do the Final Review

The people closest to a proposal are the least likely to catch its gaps, inconsistencies, and assumptions. Before submission, bring in fresh eyes — ideally someone unfamiliar with the program — to read the application as a reviewer would. Our free Mock Review Toolkit walks your team through a simulated scoring process to surface weaknesses before you submit.

 

Mistake #9: Asking for Letters of Commitment With Only a Few Days’ Turnaround

Letters of commitment from partners, subcontractors, and community stakeholders take time to draft, route for approval, and return. Requesting them at the last minute results in generic, unconvincing letters — or missing letters entirely. Build commitment letter requests into your timeline at least three to four weeks before the deadline.

 

Mistake #10: Applying Without Assessing Your Organization’s Competitiveness

Federal grants are highly competitive. Before investing significant staff time in an application, assess whether your organization is genuinely positioned to compete — and to implement the award if received. Our free Grant Readiness Guide can help you evaluate your readiness honestly before you commit to the process.
