65. Sustainability Models
By the end you'll be able to
- Name the four most common sustainability strategies and the conditions under which each is credible.
- Replace "we will seek more grants" with documented, specific pathways.
- Support sustainability claims with evidence such as MOUs, fee schedules, or board resolutions.
- Project a funding mix across Years 2 and 3 of a multi-year program.
Every reviewer eventually asks the same question: what happens when this grant ends? The wrong answer is "we will apply for more grants," because it signals that the organization plans to depend on the same funder, or its peers, indefinitely. Funders want to see that their investment will produce something that outlasts their dollars, whether that is a sustained program, an embedded capability, or a revenue stream that becomes self-supporting. In this lesson you will learn to build sustainability plans that pass that test.
You will work through the four most common sustainability strategies and when each one is credible: revenue diversification (earned fees, contracts, individual giving), institutional embedding (the program is absorbed into a school district, health system, or municipal budget), partnership commitments (named partners who have agreed in writing to absorb specific costs), and graduated funder transition (a documented plan that moves from one funder type to another over a defined period). You will learn what reviewers find believable, what they dismiss as wishful, and how to support each claim with evidence such as MOUs, letters of intent, fee schedules, or board resolutions.
By the end of this lesson you should be able to draft a sustainability plan with at least two named revenue or absorption pathways, project the funding mix across Years 2 and 3, and defend each assumption when a program officer probes it during the review.
Common mistakes
These are the traps learners hit most often on this topic. Knowing them in advance is half the fix.
Naming sustainability strategies the organization has never tried.
Promising a fee-for-service model without a fee schedule, or a major gifts program without a development plan, signals improvisation. Stick to strategies the organization can already partly demonstrate.
Burying sustainability in the last paragraph.
Reviewers look for sustainability specifically. A buried, vague paragraph at the end of the proposal reads as an afterthought.
Practice problems
Try each on paper first. Click Show solution only after you've made a real attempt.
- Problem 1Draft a sustainability paragraph for a three-year youth mental health program with a $300K annual budget that will end its current foundation funding at the close of Year 3.
Show solution
By the close of Year 3, the program will be sustained through three documented pathways. First, the regional school district has signed an MOU (attached) committing to absorb the two embedded clinician positions (72,000 in Year 3 based on the current panel growth rate, and will continue post-grant. Third, two private foundations have indicated interest in a three-year transition grant (letters of intent attached) covering the remaining $60,000 in Years 4 through 6. The combined pathways replace 100 percent of current grant revenue with a diversified mix that does not rely on this funder for continuation.
Practice quiz
- Question 1Which sustainability statement is most credible to a reviewer?
- Question 2Institutional embedding as a sustainability strategy means
- Reflection 3Why does "we will apply for more grants" weaken rather than strengthen a sustainability plan?
Lesson 65 recap
Strong sustainability plans name specific pathways, quantify each one, and attach supporting evidence. The goal is to reduce dependence on the current funder, not extend it.
