The document describes a system for measuring the impact of teacher learning events. Teachers are sent two post-learning surveys: an event evaluation survey to assess the quality of the learning event, and a post-event checkout survey to identify which skills teachers believe they will consistently include in their teaching practices after the event. Comparisons are made between teachers' pre-and post-event responses to track the impact of the learning. The document provides examples of these surveys being sent and completed by a teacher named Ashley after a learning event on October 18, 2017.
