We use longitudinal data from North Carolina and Washington to study the extent to which four processes--teacher attrition from each state workforce, teacher mobility within districts, teacher mobility across districts, and teacher hiring--contribute to "teacher quality gaps" (TQGs) between advantaged and disadvantaged schools.
