This brief provides a snapshot of the rules governing classroom observations used in teacher evaluations in selected Race to the Top grantees. The information was collected in response to a technical assistance request to the Reform Support Network (RSN) from Georgia, where education leaders charged with designing that State's teacher evaluation system were interested in learning more about the policies and guidelines that other States had established regarding classroom observations. The RSN collected publicly accessible policy data from 11 Race to the Top grantees: Colorado, Delaware, the District of Columbia, Florida, Louisiana, Illinois, New York, North Carolina, Ohio, Rhode Island and Tennessee. The analysis presents the policy approaches to conducting teacher observations taken by these States. The analysis does not attempt to present a comprehensive or exhaustive overview of teacher evaluation policy, nor is it an effort to recommend or assess the quality of these policies. The information is intended to help States and local educational agencies (LEAs) charged with designing teacher evaluation systems to learn more about the policies and guidelines that other States have established regarding classroom observations.
