Classroom Assessment Scoring System (CLASS)
CLASS is a research-based observation instrument developed at the University of Virginia that measures the quality of teacher-student interactions. Unlike rubric-based evaluation tools, CLASS uses a 1-to-7 scoring scale across three broad domains and is widely used in pre-K through 12th grade settings, Head Start programs, and teacher preparation.
Used nationally in Head Start programs, pre-K settings, and school districts across multiple states.
