Classroom Assessment Scoring System

CLASS® is a flexible tool that focuses on the heart of great teaching: the teacher-student interactions proven to drive learning and development. Over 200 research studies demonstrate that children in classrooms with more effective teacher-student interactions, as measured by CLASS, have better social and academic outcomes. CLASS is included in 23 states’ QRIS measures for one simple reason: CLASS works.

Improve Teaching Quality

Research shows that, with the right supports, teachers can improve their interactions with children to cultivate supportive, structured, and engaging classroom experiences across the CLASS domains every day. In collaboration with Teachstone, the experts who developed the CLASS, we’ve designed tools to help.
