Every Moment Matters

As the interactions company, we help educators ignite the spark of learning through the power of CLASS. This broad picture of classroom life allows educators to understand how curriculum and instruction come together to enhance children’s learning and development. Learn how to shift your continuous quality improvement efforts to what matters most—life-changing interactions between teachers and children.

CLASS Versions

The CLASS® now comes in two versions: CLASS 2008 for Infant, Toddler, Pre-K, Upper Elementary, and Secondary and CLASS 2nd Edition for Pre-K—3rd. Both tools focus on the power of meaningful interactions. CLASS 2nd Edition brings enhancements around equity and impact.
