Teacher turnover has adverse consequences for student achievement and imposes large financial costs for schools. Some have argued that high-stakes testing may lower teachers' satisfaction with their jobs and could be a major contributor to teacher attrition. This study uses data on individual students and teachers from Georgia's statewide longitudinal data system from 2007/08-2017/18 to measure the effect of testing pressures on teacher mobility choices. A "difference-in-differences" approach is used to compare changes in mobility over time in grades/subjects that discontinue testing vis-à-vis grades/subjects that are always tested.
