The Classroom Assessment Scoring System® (CLASS)

Interactions matter. And, CLASS is the way to focus, measure, and improve your interactions to drive impact.

Single Focus. Big Impact.

CLASS not only defines teaching quality through the lens of interactions, it provides the ability to measure and improve the interactions that matter most for children’s outcomes. And, it’s a journey of continuous improvement that is data-driven.

As you implement CLASS, you will:

• Focus on high-quality interactions and create a shared understanding of quality in your program
• Measure the quality of interactions to create a system that enables data-driven improvement
• Improve teaching quality through tailored and individualized professional development

Make the Switch to CLASS 2nd Edition When You're Ready

Every program is on a different part of its quality improvement journey, and we recognize that transitions take time. We’re here to support your program as you make the move to CLASS 2nd Edition. We anticipate that programs may need up through the school year 2024-2025 to prepare.

During your transition period, we recommend:

1. Learning about CLASS 2nd Edition.
2. Training your observers and educators on the enhancements with this new version.
3. Continuing using CLASS 2008 until you have set a date for when you plan to switch observations to CLASS 2nd Edition.

Over 200 research studies prove children in classrooms with higher CLASS scores demonstrate better social-emotional, cognitive, and academic outcomes.

With a focus on research-based, developmentally appropriate interactions, CLASS is used across all ages, all classroom settings, and alongside any curriculum.

CLASS is the only assessment system that provides teachers the research-proven insights, skills, and strategies they need to improve interactions, the most critical component of their teaching practices.

Our CLASS online platform, myTeachstone, streamlines the data collection, coaching, and professional development processes, making it easier than ever to improve teacher-student interactions.
