The Promise of CLASS®

A Better Way to Measure and Improve Teaching Quality

CLASS uses research-driven insights to improve how teachers interact with children every day to cultivate supportive, structured, and engaging classroom experiences.

Any Classroom. Any Grade. Any Curriculum.

CLASS is a flexible tool that focuses on the heart of great teaching: the teacher-student interactions proven to drive learning and development.

Infant, Toddler, and Pre-K CLASS helps child-care providers nurture children's early learning while responding to their needs. As children enter preschool, their sense of themselves is grounded in, and dependent on, relationships. CLASS helps preschool teachers foster a secure, supportive base for learning and exploration.

Grades K–5 K–5 learners need a balance of guided interactions and independence to keep them engaged. CLASS helps teachers create supportive, dynamic classrooms that foster autonomy, critical thinking, and positive peer collaboration.

Grades 6–12 Upper grades need even more opportunities for constructive independence and analysis and inquiry while adding the challenges of a student population passing through adolescence. CLASS provides teachers with a framework for balancing emotional support, classroom organization, and instructional support that leads to better student outcomes.

You can work on the environment, you can address skills, but it’s very hard to teach the qualities of rich interaction.

I’m talking a lot more with the children. I look in their eyes and explain what they are doing.

CLASS: A Leading QRIS Standard

CLASS is included in 23 states with QRIS metrics for one simple reason: CLASS works.

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.

This proven positive impact has made CLASS a critical component of program quality in early childhood education.
