CLASS was developed in 2008 by education researchers at the University of Virginia’s Center for Advanced Studies in Teaching and Learning (CASTL) to scientifically capture the essence of great teaching.
Data Driven Improvement
The CLASS model is the most researched framework for assessing teacher-child interactions, measuring their quality, and turning those metrics into meaningful suggestions for improvement.
Validated Professional Development
CLASS-based professional development programs are not only built on a strong research foundation—they’ve been proven by dozens of studies to impact classroom quality, improve child outcomes, and increase teachers’ job satisfaction.
