This analytic memo presents an analysis of ratings data from the first year of Chicago's new REACH teacher evaluation system. The primary purpose of this memo is to provide implementation support for key stakeholders in Chicago. The data and analysis presented here can also provide context for the findings in Teacher Evaluation in Practice: Year 2 Teacher and Principal Perceptions of REACH. A more in-depth report analyzing both Year 1 and Year 2 ratings data will be released in 2015.

A working paper is a work in progress intended to contribute to current conversations in research, policy, and practice in a timely manner. The findings, interpretations, and conclusions expressed herein are preliminary thoughts solely of the author(s) and shared with permission of the author(s). These preliminary findings, interpretations, and conclusions may change upon further interrogation and collaboration with UChicago Consortium colleagues and other stakeholders in our work.
