The Classroom Assessment Scoring System™ (CLASS)

CLASS is an observation tool that focuses on the effectiveness of classroom interactions among teachers and children, because it is these daily interactions that promote children’s social and cognitive development.

CLASS observation tools have been developed for Infant, Toddler, Pre-K, K-3, Upper Elementary and Secondary age groups.

At every age level, the CLASS measure focuses on interactions that support learning. No matter which age or grade level of the tool you use, developmentally appropriate interactions are organized into domains and dimensions:
