HAYLOWWhat Data Your Nonprofit Should Track to Prove Impact
You could measure a hundred things. Most of them will not help you keep a funder.
More data is not more proof. Programs drown in numbers that feel productive to collect and prove nothing — while the handful of metrics a funder actually weighs go untracked. Closing that gap is less about collecting more and more about collecting the right few, consistently.
Vanity metrics vs. proof metrics
| Feels like impact | Actually proves impact |
|---|---|
| Total attendees, social reach, hours delivered | Whether the people you served changed |
| How busy the program was | How good and how consistent the work was |
The short list worth tracking
- Reach — who you served, enough to show the population is right.
- Quality — session scores against a rubric, so "good" is measured, not assumed.
- Progress — goals set and met, participant by participant.
- Retention — who stayed, since change needs time in the program.
- Outcomes — the one or two changes your program exists to create.
Start with one you can capture reliably this month. A metric you track every time beats five you track when you remember.
Where to go next. Signal shows which layer is thin in thirty seconds. The book turns the short list into a working system, and CALIBR tracks the quality metric for you, session by session.
Track less, prove more. The right six numbers beat a hundred you cannot stand behind.
