Classroom Assessment Scoring System (CLASS) - Qualistar

CLASS® Teacher-Child Interactions Observation

Improving child outcomes through teacher-child interactions

The Classroom Assessment Scoring System, known as CLASS®, is a valid and reliable class observation tool focused on teacher-child interactions. The CLASS observation measures the emotional, organizational, and instructional support offered by the teacher. Results can be used to improve teacher effectiveness and promote professional development and growth. Participation in the CLASS observation can add up to ten points in your Colorado Shines rating.

Our team is certified on the CLASS® tool for infant, toddler, preschool, and K-3 classrooms and can be conducted in both English and Spanish. We hold our assessors to strict reliability standards. What makes our CLASS® observation so unique is that our work does not end when we leave the classroom.

Participants in the CLASS® observation quality improvement process receive:

  • An experience with professional and courteous assessors
  • An individualized quality improvement plan with classroom-specific recommendations
  • Clear direction for administrators and teachers on how to make strategic decisions that improve quality
