TEACHER AND STUDENT
INTERACTIONS
Every day, teachers make countless real-time decisions and
facilitate dozens of interactions between themselves and their
students. Although they share this commonality, educators all
over the country often talk about these decisions and
interactions in different ways. The Classroom Assessment
Scoring System (CLASS), developed at the University of
Virginia’s Center for Advanced Study of Teaching and Learning,
helps educators view classrooms through a common lens and
discuss them using a common language, providing support for
improving the quality of teacher-student interactions and,
ultimately, student learning.
