The rapid pace of change on teacher evaluation continues across the states in 2012. Since 2009, 36 states and the District of Columbia Public Schools have made policy changes on their books related to teacher evaluation. In the few short months since the National Council on Teacher Quality (NCTQ) published "State of the States" and the 2011 "Yearbook," 15 states have made teacher evaluation and/or tenure policy changes with seven states--Connecticut, Hawaii, Louisiana, New Jersey, Oregon, Pennsylvania and South Dakota--adopting significant new policies. This brief includes the latest breaking and most up-to-date findings on how states are evaluating teacher performance and using the results for decisions of consequence such as granting teachers tenure. Appended are: (1) States with Significant Teacher Evaluation and Tenure Policies in 2012; and (2) State Teacher Evaluation Policy Profiles. (Contains 1 footnote.)
