2019 Teacher and Principal Evaluation Policy
The state should require objective measures of student growth to be included in a teacher's evaluation score.
Impact of Student Growth: Connecticut requires that 45 percent of a teacher's evaluation rating must be based on attainment of between one and four goals and/or objectives for student growth. The student growth component "shall not be determined by a single, isolated standardized test score."
State's Role in Evaluation System: Connecticut districts must develop teacher evaluation systems consistent with the state's guidelines. Connecticut's SEED model is aligned with these guidelines. Districts must submit evaluation plans for review and approval by the state.

7A: Measures of Student Growth
Many factors should be considered in formally evaluating a teacher; however, nothing is more important than effectiveness in the classroom. Value-added models are an important tool for measuring student achievement and school effectiveness. These models have the ability to measure individual students' learning gains, controlling for students' previous knowledge and background characteristics. While some research suggests value-added models are subject to bias and statistical limitations, rich data and strong controls can eliminate error and bias. In the area of teacher quality, examining student growth offers a fairer and potentially more meaningful way to evaluate a teacher's effectiveness than other methods schools use.
Unfortunately, districts have used many evaluation instruments, including some mandated by states, which are structured so that teachers can earn a satisfactory rating without any evidence that they are sufficiently advancing student learning in the classroom. Teacher evaluation instruments should include factors that combine both human judgment and objective measures of student learning.
