Empirical evidence shows that disadvantaged students tend to have less-qualified and less-effective teachers than their more-advantaged peers. These teacher quality gaps (TQGs), which have existed for decades and across many measures of student disadvantage and teacher quality, are an important factor explaining student achievement gaps between…

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. We first…

A number of studies have demonstrated that teachers are inequitably distributed across student subgroups by input measures, like experience and qualifications, as well…
