Program Assessments Conducted by MSDE
What is CLASS®?
The Classroom Assessment Scoring System (CLASS®) is an observation tool that looks at the big differences made by everyday interactions within the classroom. Examples include: how educators welcome and respond to children, guide their behavior and engagement, ask questions, and help them think and learn.
During a CLASS® observation, a certified observer watches how educators connect with children, engage them in learning, and support their development through interactions.
To understand and measure what children experience on a normal day, CLASS® looks at important areas including:
- Emotional support: How educators create warm, responsive environments where children feel safe, supported, and connected.
- Classroom organization: How educators support positive behavior and plan for routines and activities that make the most of learning time.
- Instructional support: How educators use conversations, questions, feedback, and other interactions to deepen children’s thinking, language, and learning. (Pre-K tool only)
CLASS® has different measurements for different age groups:
- Infant/Toddler CLASS®: Birth to age three
- Pre-K-3rd CLASS®: Age three and up
How does CLASS® work?
Programs participating in Maryland EXCELS with a draft or published quality rating 3 or 4 can request a CLASS® observation by using the form available in ACR 2 in the Maryland EXCELS online system. Programs with a quality rating 5 will be contacted directly to schedule observation visits.
During a CLASS® observation, a trained observer spends approximately two hours in the classroom, in 20-minute intervals, observing and measuring what educators and children say and do during daily activities and routines.
After observation, the observer shares their scores and feedback about which interactions were strongest and where improvements could be made.
How can programs prepare for a CLASS® observation?
Conducting a Maryland EXCELS self-assessment gives your program an excellent preview of the interactions that are measured during a CLASS® observation.
Self-assessments are available to all programs that are working to meet the requirements of ACR 2 at level 3.
