The impact question, honestly
Funders ask what difference an organisation makes, and the honest answer for most small charities is that they do not know with any rigour. That is not a criticism, and pretending otherwise is where the trouble starts.
The difficulty is structural. Establishing that your programme caused an improvement requires knowing what would have happened without it, and you do not observe that. The people you helped might have improved anyway. The ones who improved most might have been the ones already most likely to. And the people for whom it did not work may simply have stopped coming.
The machinery for handling this properly is covered elsewhere in this catalogue, in the cursus on knowing what actually works: comparison groups, randomisation, and why before-and-after misleads. That machinery is real, and it is mostly out of reach for an organisation running a programme for forty people on a grant of thirty thousand.
So the practical question is not how does a small charity run a rigorous evaluation. It is what can a small charity claim honestly, and how does it get better information without pretending to a rigour it cannot afford.
The answer has three parts, developed through this lesson. Be precise about what you actually observed. Be explicit about what you cannot separate. And collect the qualitative information you can, properly, because it is genuinely informative even though it is not causal evidence.
That is a defensible position, and funders who know the sector recognise it as more credible than a confident impact figure with nothing behind it.
