A new study from Mathematica looks at a pilot program in seven impoverished districts that offered transfer-incentives to high-performing teachers:

By offering $20,000 per teacher, seven school districts piloting a transfer-incentive strategy, known as the Talent Transfer Initiative (TTI), filled 90 percent of their targeted vacancies in hard-to-staff schools with some of the districts’ highest-performing teachers. A new study from Mathematica Policy Research highlights the implementation experience and intermediate impacts of TTI, which is intended to expand disadvantaged students’ access to the most effective teachers. Previous research conducted by Mathematica shows that, on average, low-income middle school students are significantly less likely to have access to the highest-performing teachers.
