This document provides an overview of project monitoring and evaluation. It defines monitoring as the regular collection of information to track changes over time, and evaluation as analyzing the effectiveness and impact of a project. The key purposes of monitoring and evaluation are to assess results, improve management, promote learning, ensure accountability, and understand stakeholder perspectives. Effective monitoring and evaluation considers outputs, processes, outcomes, impact, and reach. Internal evaluation is done by project staff, while external evaluation involves independent evaluators assessing how funds were used. Distinctions are made between monitoring as an ongoing activity and evaluation as an in-depth assessment.
