These trainings consist of two full days of in-depth CLASS® content and coding practice using video observations of the CLASS® tool of your choice. The participants will have a variety of activities that will allow them to understand what the CLASS® tool measures, understand the link between effective teacher-child interactions and learning gains, identify the teacher-child interactions associated with each CLASS® dimension, and code classroom videos using the CLASS® measure. These trainings prepare you to be a certified CLASS® assessor. These trainings have been developed by Teachstone® and are delivered by licensed affiliate trainers.
