Examining the Relationship Between Teacher Performance Ratings and District Under the Ohio Teacher Evaluation System

The soundness of the Ohio Teacher Evaluation System (OTES) depends heavily on evaluators’ uniform interpretation of the qualitative Teacher Performance rubric. This study investigates the relationship between teachers’ district of employment, and the Teacher Performance ratings they receive under OTES. For Ohio districts that implemented OTES in 2012-2013, 2013-2014, and 2014-2015, the proportion of various Teacher Performance ratings and Student Growth Measures ratings are examined and compared to statewide proportions, using descriptive data and a log-linear model. Findings speak to the importance of a continued or renewed emphasis on fostering uniform interpretation and implementation of teacher evaluation rubrics and systems.

Student growth measures: What we’ve been missing

The move toward assessments that measure student growth, rather than just proficiency, has been perceived as an improvement in state accountability systems. However, Michael Watson explains that, for many students, these measures present an incomplete picture. Because they are based on grade-level assessments, any growth achieved by students who are above or below grade level is lost. He recommends the use of adaptive assessments that incorporate material from multiple grade levels.
