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.
