The Measurement and Evaluation (M&E) Checklist is a resource that guides users through an evidence-building process to design, refine, and test a solution in collaboration with stakeholders from a priority community. The checklist includes four documents, one for each of the evidence-building phases: Design the Solution (Phase 1), Refine the Solution (Phase 2), Assess for Early Evidence of Success (Phase 3), and Validate Effectiveness (Phase 4). The checklist activities focus on iterative learning, which may mean completing a phase multiple times, moving backwards to a previous phase, or abandoning a solution altogether.

This portion of the M&E Checklist guides users specifically through Phase 2 of the evidence-building process, which explores how to refine a solution based on lessons learned during implementation. The goal of Phase 2 is to develop descriptive evidence that the refined solution was successfully implemented in the priority community.
