The country is at a crossroads in implementing measures of educator effectiveness in K-12 classrooms. While the vast majority of states require student growth and achievement to be factored into teacher and principal evaluations, most states and school districts are now grappling with the practical realities of implementing these policies. In this report, the National Council on Teacher Quality (NCTQ) presents the most comprehensive and up-to-date policy trends on how states are evaluating teachers. The report also breaks new ground by providing a look at the policy landscape on principal effectiveness. Finally, NCTQ continues to examine state efforts to connect the dots--that is, use the results of evaluations to better inform practice and make decisions of consequence for teachers in the 50 states and the District of Columbia.
