Teacher and Principal Evaluation Policy
The state should require objective measures of student growth to be included in a teacher's evaluation score. This goal is reorganized for 2019.
Impact of Student Growth: Louisiana requires that 50 percent of a teacher's evaluation rating is comprised of student growth (35 percent is measured by value-added measures for teachers who have VAM and 15 percent is measured by student learning targets). For teachers of grades and subjects tested by state standardized assessments, student growth on such tests is used to measure their impact on student learning. For teachers of grades and subjects not tested by state standardized tests, targets established by teachers and evaluators are used to measure their impact on student learning.
State's Role in Evaluation System: Louisiana requires teachers to be evaluated under its statewide evaluation system, Compass.

Due to Louisiana's strong policies in this area, no recommendations are provided.

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.
