CLASS is an observational instrument developed at the Curry School’s Center for Advanced Study of Teaching and Learning (CASTL) to assess teacher-student interactions in PK-12 classrooms and in settings serving infants and toddlers. It describes multiple dimensions of interaction that are linked to student achievement and development and has been validated in over 6,000 classrooms. CLASS can be used to reliably assess classroom quality for research and program evaluation and also provides a tool to help new and experienced teachers become more effective.
Child Care & Early Education Research Connections, launched in 2004, promotes high quality research in child care and early education and the use of that research in policy making. Our vision is that children are well cared for and have rich learning experiences, and their families are supported and able to work. Through this website, we offer research and data resources for researchers, policy makers, practitioners, and others.
