CHARLOTTESVILLE, VA — August 1, 2025 — Teachstone, the pioneering organization behind the CLASS® (Classroom Assessment Scoring System) framework, announces the launch of the CLASS® 2nd Edition Infant–Toddler Product Suite.
CLASS is a powerful research-based professional learning solution that has been validated by hundreds of research studies for measuring and improving educator-child interactions in ECE programs. Informed by over a decade of user feedback, CLASS 2nd Edition builds on this proven foundation to strengthen the effectiveness of interactions from birth through 3rd grade. The suite offers robust tools and guidance, simplified implementation, and engaging growth-focused learning experiences.
“This launch is more than a product update. It is a renewed commitment to the educators, leaders, and families we serve,” said Karlo Young, CEO of Teachstone. “We heard the call for greater alignment, clarity, and cohesion across tools. The CLASS 2nd Edition Infant Toddler Suite is our response. It reflects our belief that every child deserves consistent, high-quality interactions starting from day one.”
An integrated system to support continuity in infant and toddler settings
Previously, infant and toddler settings used separate CLASS tools, often resulting in inconsistent training and more complex implementations. With this release, CLASS users now benefit from:
- One cohesive tool that offers simplified certification pathways for observers, trainers, and educators
- Role-specific learning experiences to build lasting skills and support meaningful improvement in practice
- Updated videos, examples, and supports grounded in the realities of today's learning settings
- Training and support in Spanish for expanded access and impact
“We designed this suite to be both educator-first and implementation-ready,” said Hannah Templeton, VP of Product at Teachstone. “It’s not just about measurement—it’s about making daily interactions more meaningful and sustainable. The updated content, streamlined pathways, and aligned supports help programs scale quality in a way that supports every child.”
