The difference between outputs and outcomes, and three measures any small program can track.
Funders want to know that your work makes a difference. You don't need special software; you need to decide what to count and count it consistently.
Outputs and outcomes
- Outputs are what you did: 40 youth attended 20 sessions; 12 volunteers gave 150 hours.
- Outcomes are what changed for people: more students reading at grade level; fewer missed school days; a family moved into stable housing.
Start with three measures
- How many people you served (count each person once, separately from visits).
- How often they took part (sessions attended).
- One outcome that fits your mission, measured with a simple before-and-after question, a teacher or caseworker report, or a short survey.
Good habits
- Decide the measure before the program starts, and write down how you measure it.
- Record a starting point (baseline) so you can show change.
- Collect only what you need. Avoid unnecessary personal information, especially about children and vulnerable people, and get consent for stories and photos.
- Report honestly. A small, well-documented result is more credible than a large claim you can't back up.
