Getting ready for a Colorado Shines Rating? Or just want to learn more about the Environment Rating Scales and recent research on best practices in the classroom? In this three-hour overview of all three Environment Rating Scales, Third Edition (Early Childhood Environment Rating Scale / Infant-Toddler Environment Rating Scale / Family Child Care Environment Rating Scale), we discuss "The Big Three" components (access to materials, teaching interactions, and relationships), as well as overarching definitions and themes present in all three scales. Participants will engage in discussions and activities and will leave with an action plan to support the implementation of these ideas in their classrooms.
