CLASS® 2nd Edition Pre-K-3rd
A newly reimagined system for observing and supporting the quality of interactions in pre-K through 3rd-grade settings.
Why the update?
The original Pre-K and K-3 CLASS tools served programs for over 10 years. But learning settings—and educators—have changed. The CLASS® 2nd Edition Pre-K–3rd suite reflects current research and field feedback – yet continues to measure the same overall domains, dimensions,and indicators that have always guided CLASS Observations.
