Access to high quality educators is critical to the future of American children and to the economic success of our nation. We study private and public efforts to improve the effectiveness of teachers and principals in our nation's schools, helping decision makers understand what works and why.

How Did it Get this Way? Disentangling the Sources of Teacher Quality Gaps through Agent-Based Modeling
We develop a novel simulation methodology to study the extent to which three interrelated processes—teacher attrition from the state teaching workforce, teacher mobility between teaching positions, and teacher hiring for open positions—contribute to “teacher quality gaps” (TQGs) between students of color and other students in K–12 public schools.
