This document provides an overview of the Most Significant Change (MSC) technique for monitoring and evaluation. MSC is a participatory approach that collects qualitative stories from participants about program impacts in their own words. It involves collecting stories, discussing and categorizing them, selecting the most significant changes, and using the insights for program improvement. The document outlines the MSC process, appropriate and inappropriate uses, strengths such as participatory learning and weaknesses like high costs. It also provides an example of MSC in action through a video link and proposes an activity for participants.
