2017 Teacher and Principal Evaluation Policy
The state should have a data system that contributes some of the evidence needed to assess teacher effectiveness. The bar for this goal was raised in 2017.
Teacher of record: Michigan defines teacher of record as the certificated teacher who provides instruction, tests, and quizzes and evaluates performance, and gives a grade. However, this definition is not explicitly articulated in state policy.
Teacher roster verification: Michigan does not have a process in place for teacher roster verification.
Linking student-level data and teacher performance: Michigan does not appear to have the capacity to link student-level data and teacher performance through its statewide longitudinal data system. Students are assigned unique identifiers to match student-level data in elementary, secondary, and post-secondary data systems, and individual teacher data are connected to teacher preparation colleges; however, it is unclear whether capacity exists to explicitly link student-level data and teacher performance.
Teacher mobility data: Michigan recently published a White Paper entitled,"Teacher Turnover in Michigan: A Look at Teacher Mobility and Attrition Rates," which reports trends in school-to-school mobility and attrition within the state teacher workforce. A wide range of teacher mobility data are presented, including the number and percentage of state public school teacher stayers, movers, and leavers between 2004-2005 and 2016-2017; and turnover/stability data disaggregated by teacher or school characteristic in base years
2011-2012 and 2015-2016.

Formalize a definition of teacher of record that can be used to provide evidence of teacher effectiveness.
Although Michigan appears to have a working definition for teacher of record, NCTQ strongly urges the state to incorporate this definition into articulated state policy; doing so will help ensure that data provided through the state data system are actionable and reliable.
Institute a process for teacher roster verification.
Michigan should clearly articulate a process for teacher roster verification. This is of particular importance for using the data system to provide evidence of teacher effectiveness.
Link student-level data to teacher effectiveness.
Michigan should ensure that it has a longitudinal student data system with the capacity to link student-level data to teacher performance, consistent with applicable privacy constraints. This will allow the state to identify whether certain groups of students are being systemically underserved by ineffective teachers.
Michigan recognized the factual accuracy of this analysis, and was helpful in providing NCTQ with the facts necessary for this analysis.
7E: Data Systems Needed for Evaluation
It is an inefficient use of resources for individual districts to build their own data systems for value-added analyses. States need to take the lead and provide districts with state-level data that can be used not only for the purpose of measuring teacher effectiveness, but also to track teacher mobility across the state. As such, multiple years of data are necessary to enable meaningful determinations of teacher effectiveness and to identify staffing trends.
Teacher effectiveness analysis, including teachers' value-added measures, requires both student and teacher identifiers and the ability to match test records over time. Such data are useful not just for teacher evaluation, but also to measure overall school performance and the performance of teacher preparation programs.
States need to have some advanced elements in place in order to apply data from the state data system fairly and accurately to teacher evaluations. Each state must have a clear definition of "teacher of record" that connects teachers to the students they actually instruct and not just students who may be in a teacher's homeroom or for whom the teacher performs administrative but not instructional duties. There should also be in place a process for roster verification, ideally occurring multiple times a year, to ensure that students and teachers are accurately matched. Systems should also have the ability to connect multiple educators to a single student. While states may establish different business rules for such situations, what is important is that the mechanism exists, in recognition of the many possible permutations of student and teacher assignments.
Additional elements are needed to use data to assess teacher supply and demand. For example, states should include in their data systems means of tracking when teachers leave schools or districts, as well as when they re-enter new ones, and should make these data publicly available. These data can support the state's effort to build a cohesive picture of the state's teacher labor market and workforce needs.
