All Things CLASS

Introducing the CLASS® 2nd Edition Crosswalk!

Are you transitioning to CLASS 2nd Edition? We've created a comprehensive crosswalk to help you bridge your existing CLASS knowledge with the updated 2nd Edition tools.

What's Inside: This crosswalk gives a high-level overview of key updates across Infant-Toddler and Pre-K–3rd grade tools, including:
✨ Updated dimension definitions that better capture teacher–child interactions across all settings
✨ Enhanced indicator definitions for clearer scoring
✨ Refined behavioral markers grounded in current child development research
✨ Inclusive language supporting diverse learners and program types
✨ Improved clarity and usability throughout the tools

Why This Matters: CLASS 2nd Edition builds on the same trusted framework you know. By consolidating age-level tools and refining language, we've made CLASS more accessible while keeping the core structure that makes it the most researched and validated observational system in the field.

Good News: You can build on your existing CLASS investments! The foundational concepts remain unchanged, ensuring reliable observations from birth through 3rd grade-now with enhanced guidance.

Thanks Angela! Since meals/ snacks are no longer listed as an activity setting item, would this be recorded as a routine/ transition? What content area is most appropriate when documenting transitions or meals? I would often note language arts but that is no no longer an option so I would love any guidance on these particular routines.

Thank you!
