How to Write a Case Study That Attracts Donors and Partners

A case study is evidence. It says: this is not just something we claim. This is something that happened, to a real organisation or community, with measurable outcomes. For donors and partners evaluating your credibility, a compelling case study can do more persuasive work than any amount of general messaging about your impact.

Most NGO case studies fail because they are too general, too long, or written from the organisation's perspective rather than the beneficiary's. Here is the structure that consistently works.

Start With the Specific Situation

Open with a precise description of the situation before your intervention. Who was the organisation, community, or individual you worked with? What was their specific challenge or context? Be concrete and specific. Avoid generalisations. "A women's savings group in the Western Region" is better than "a community group." The more specific the setup, the more credible the outcome.

Describe the Intervention Clearly

What exactly did you do? Walk the reader through your approach in enough detail that they understand both the method and the logic. This is not a programme brochure — it is an honest account of how you worked and why you made the choices you made. Include what you adjusted along the way. Funders and partners know that real programmes are not linear. Showing that you adapted builds credibility.

Quantify the Change

What changed as a result? Wherever possible, express change in numbers: income increased by X, beneficiaries reached, time saved, costs reduced, coverage expanded. Numbers make change concrete and comparable. They also demonstrate your measurement capacity — a signal that funders increasingly value.

Pair the numbers with a human quote. A direct quote from a beneficiary or community leader, in their own words, gives the numbers emotional resonance. The combination of data and voice is more persuasive than either alone.

Draw a Replicable Lesson

Close with what can be learned from this case. What conditions made this work? What would you do differently? What does this tell us about the problem or the approach more broadly? Case studies that include genuine learning — including what was hard — are more credible than smooth success narratives.

Keep your case study to 600-900 words. Make it scannable with clear headers. Add one or two photographs if you have them. Publish it on your website and share it with your donor list. A library of three or four strong case studies is one of the most powerful assets an NGO can build.
