This study examines the perceptions of teachers in one Midwest school district relative to the current teacher evaluation system used in the district as well as a new model of teacher evaluation connected to Missouri's educator standards. To fully understand the perspective of the teachers, this study incorporates a mixed-methods approach which provides a variety of quantitative and qualitative data for analysis. Using survey data and focus group interview data, this study revealed that teachers perceive limitations associated with the current, more traditional evaluation process. Teachers understand benefits to the new Missouri model, but have reservations about its impending implementation. This study provides implications for the district as it moves forward with changing its teacher evaluation process.
