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: Oregon requires all teachers to set two Student Learning and Growth (SLG) goals. The summative evaluation must consider the data gathered from goals that impact student learning and growth; however, it is up to individual districts to determine the degree to which these data informs the summative evaluation.
State's Role in Evaluation System: Oregon requires its districts to formulate their own evaluation instruments based on performance standards and performance goals established by the districts.
Framework (revised 2018-2019): https://www.oregon.gov/ode/educator-resources/educator_effectiveness/Documents/oregon-framework--for-eval-and-support-systems.pdf Oregon Revised Statutes 342.850 OAR 581-022-2410
Due to Oregon'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.
