CLASS focuses on interactions between teachers and children and how teacher engagement, classroom materials, and children’s activities combine to enhance learning. Each age specific CLASS instrument supports a consistent approach to measuring quality practices across early childhood and school-age environments.
The CLASS instruments are comprised of domains and dimensions that reflect quality classroom interactions. CLASS domains include: Responsive Caregiving, Emotional Support, Classroom Organization, Instructional Support, Emotional and Behavior Support, and Engaged Support for Learning. CLASS dimensions include easily observable behavior markers that reflect consistently occurring quality practices in the classroom. Behavior markers include but are not limited to, eye contact, acknowledging children’s emotions, teacher involvement in children’s activities, engaging in meaningful back and forth exchanges, and using a variety of words in communication.
CLASS can be used in center-based programs. There are four CLASS instruments used to assess programs in Pennsylvania:
*Age ranges for CLASS have been aligned to Pennsylvania Department of Human Service Child Care regulations age levels.
External CLASS assessments are conducted by a certified CLASS observer from the Program Quality Assessment (PQA) team. Assessments occur in four 15-20-minute observation cycles.
Internal CLASS assessments are conducted by the program’s internal assessment team. Programs partner with the Quality Coach and PQA team when planning for and conducting internal assessment, and when analyzing the information collected during the internal assessment process.
Information gathered during a CLASS assessment can be used by the program to help identify positive teacher interactions, as well as areas for growth. The information gathered can also be used to help create the program’s continuous quality improvement plan.

How to Conduct an Informal Internal Assessment (PDF) is a good place to start. It provides an at-a-glance of the assessment details, a list of materials to support internal assessments, links to professional learning resources, and step-by-step guidance for conducting the informal internal assessment.
The CLASS Self-Reflection Tool (PDF) was developed for Internal Assessment teams to use after receiving feedback from an Infant, Toddler, Pre-K and/or K-3 external CLASS observation. The purpose of the Self-Reflection Tool is to help early childhood and school-age professionals reflect on the current practice feedback, identify strengths and areas for growth, and begin making plans for classroom/program improvement.
The CLASS Internal Self-Reflection Tools were designed to support programs in becoming more familiar with the CLASS observation instruments, reflect on current practices, and develop goals related to teacher-child interactions. Each CLASS Internal Self-Reflection tool includes a checklist of items and open-ended questions for Internal Assessment team reflection.
