These trainings are half-day (3 hours) or full-day (6 hours) overviews of the CLASS® tool of your choice with the intention of providing a general understanding of the tool to any early childhood professional interested in learning more. 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, and identify the teacher-child interactions associated with each CLASS® dimension. These trainings have been developed by Teachstone® and are delivered by licensed affiliate trainers.
