Assessing a project’s social impact does not require a large evaluation budget. It requires clear outcomes, a few well-chosen indicators and evidence collected consistently from the start. This guide is written for project managers in NGOs and social enterprises who need a practical approach.
Define the Outcomes First
Start by writing down what should be different for participants if the project succeeds. Keep the list short and specific. “Participants find work” is a start. “Participants hold a paid job six months after training” is something you can measure.
Choose Indicators You Can Actually Collect
For each outcome, choose one or two indicators. Check that the data can realistically be collected with your team’s time, tools and access to participants. An indicator that requires follow-up visits the budget cannot cover will produce gaps, not evidence. Where funders use standard metrics such as IRIS+, align with them to make reporting easier.
Record a Baseline
Collect the same indicators at the start of the project. Without a baseline, you can describe where participants ended up but not how far they moved. If a full baseline is not possible, record at least the key indicators at enrollment.
Combine Numbers and Voices
Quantitative data shows how many people changed and by how much. Qualitative data, from interviews, open survey questions and group discussions, explains why. Both are needed. A short set of structured interviews at the end of each cohort is often enough to add meaning to the numbers.
Look for What You Did Not Plan
Ask participants and partners about unexpected effects, positive and negative. A skills program might raise participants’ confidence in ways no indicator captured, or it might take time away from family income during training. Both belong in an honest assessment.
Be Careful About Cause and Effect
Other factors influence outcomes: the local economy, other programs, family circumstances. Unless you have a comparison group, describe your project’s contribution to the change rather than claiming it caused the change on its own.
Use and Share the Findings
Review results with your team and decide what to change. Share a short summary with participants and partners, and a fuller report with funders that shows the baseline, results, methods and limitations. Over time, this record becomes the strongest evidence an organization has.
