This research and policy brief was developed to help states consider options for assessing student learning growth for the majority of teachers who teach content not assessed through standardized tests. It provides information about options for states to explore as well as factors to consider when identifying and implementing measures. The brief also focuses specifically on federal priorities to help ensure that evaluation systems meet the high expectations set for teacher evaluation. Finally, the brief emphasizes the importance of fairly measuring all teachers, including them in the evaluation process, and ensuring validity in measurement.
