Definition
An evaluability assessment is a preliminary exercise conducted before a full evaluation is commissioned. It examines whether a program is sufficiently mature, documented, and clear in its design to be evaluated meaningfully. The assessment reviews: Are the program's goals and theory of change clearly articulated? Do baseline data and comparison groups exist or can they be constructed? Is there sufficient program documentation? Are key stakeholders aligned on the program's logic? The output is a recommendation - green light for evaluation, or recommendations for strengthening the program first.
Why It Matters
Evaluating an immature program wastes resources. If the program design is not yet clear, its theory of change is still shifting, or baseline data do not exist, an evaluation conducted too early will struggle to attribute outcomes to the intervention or measure change from an unknown starting point. An evaluability assessment prevents this by surfacing readiness gaps before major evaluation resources are invested. It also identifies what documentation or data collection work needs to happen before evaluation can proceed, turning the assessment itself into a planning tool.
In Practice
An evaluability assessment typically takes 3-6 weeks and costs significantly less than a full evaluation. A small team reviews program documents (design, logframe, monitoring reports), interviews key staff and stakeholders, and documents the program's stated logic and change hypotheses. They assess: Is the theory of change internally coherent? Are outcome and impact indicators feasible to measure? Does monitoring data currently exist? Are administrative or control groups available? The team then drafts a report identifying gaps and recommending actions before evaluation proceeds. For example, an assessment might find the program's outcomes are clearly defined but no baseline data exist, requiring the program to conduct a baseline before evaluation can measure change.
