The Classroom Assessment Scoring System (CLASS) is a system for observing and assessing the qualities of interactions between teachers and students in classrooms. The CLASS measures instructional and social-emotional interactions proven to contribute to students' academic achievement and social competencies during early childhood years and elementary grades.
The CLASS is a useful tool for
who want a classroom observation tool with established links to children's social and academic development
who want a standardized and validated tool to conduct classroom observations that will help assess and improve classroom quality across grades
who want a quantitative measure of the degree to which they are successful in preparing students to meet the challenges of teaching
who want video examples of high quality teaching to use during trainings
who want to learn more about effective teaching practices
