Classroom Assessment Scoring System? (CLASS?) Manual, K-3

Effective teacher–student interactions are a primary ingredient of high-quality early educational experiences. With the popular CLASS® observational tool, schools can accurately assess classroom quality in K–3 classrooms based on teacher–student interactions rather than the physical environment or a specific curriculum. The CLASS tool

• covers three crucial domains of teacher-student interaction: Emotional Support, Classroom Organization, and Instructional Support.
• has high validity and reliability, proven through more than a decade of testing and research in over 3,000 classrooms.
• addresses a school's most urgent needs: accountability efforts, professional development, program planning, and research.
• establishes an accurate picture of the classroom through 30-minute cycles of observation and scoring, repeated up to 6 times over 3 hours.
• helps identify areas for improvement so programs can choose effective interventions for "trouble spots."

This useful manual includes detailed descriptions of the 10 CLASS dimensions, administration procedures, and a technical appendix. One copy of the CLASS® Dimensions Overview, a tri-fold reference sheet for observers, is included with the manual.

This user's guide is part of CLASS, the bestselling classroom observational tool that measures interactions between children and teachers—a primary ingredient of high-quality early educational experiences. With versions for infant programs, toddler programs, pre-K (in English and Spanish), and K–3 classrooms, the reliable and validCLASS tool establishes an accurate picture of the classroom through brief, repeated observation and scoring cycles and effectively pinpoints areas for improvement.
