Home / Services / MERL & Data / Impact Assessments

Not just what changed — what your programme changed.

An impact assessment tackles the hardest evaluation question: how much of the observed change is attributable to your intervention rather than everything else happening around it. We match the design to your data reality — from theory-based contribution analysis to quasi-experimental methods.

Our approach

How we deliver a credible impact assessment.

Design matched to your context

Difference-in-differences, matching approaches, or theory-based contribution analysis — chosen for what your data can actually support, not for fashion.

Honest attribution language

Findings framed with the confidence the design justifies; we never overclaim causality your donor's technical reviewers will reject.

Counterfactual thinking throughout

Comparison groups, secondary data and triangulation used to isolate programme effect.

Statistical rigour

Analysis in Stata/R/SPSS with documented specifications, robustness checks and replicable code.

Deliverables

What you receive.

Why Insight Bridge

Evaluators who have sat on your side of the table.

Our evaluations are led by postgraduate-qualified professionals with more than eight years coordinating monitoring, evaluation, research and learning inside SIDA- and PEPFAR/USAID-funded programmes — we know what donor technical reviewers look for because we have prepared for those reviews ourselves. Analysis is delivered with Microsoft PL-300 certified capability across Stata, R, SPSS and Power BI.
