In this three-hour overview of all three Environment Rating Scales, Third Editions (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 classroom.
