"Transfer Incentives for High-Performing Teachers: Final Results from a Multisite Experiment," examined the impact of the Talent Transfer Initiative (TTI) on both student achievement and teacher retention in 10 school districts across seven states. The initiative gave bonuses to high-performing teachers for them to transfer to and stay in low-performing schools. Transfer teachers could receive up to $20,000 over 2 academic years. The researchers matched schools in the same district with teacher vacancies at the same grade level and subject into "teams." They then randomly assigned the 165 matched teams to one of two conditions: either the principal was allowed to hire a high-performing teacher through the TTI program ("TTI team") to fill the vacancy, or the principal could only hire through normal approaches ("comparison team"). At the end of the first academic year, the study authors found no statistically significant differences in student math or reading test scores between TTI teams and comparison teams at the elementary or middle school level. However, at the end of the second academic year, elementary students from TTI teams had higher student standardized test scores, by a statistically significant margin, than those from comparison teams. With regard to retention, teachers in TTI teams were 7 percentage points more likely than teachers in comparison teams to remain in their schools 1 year after the study began, a statistically significant difference. After 2 years, the study found no statistically significant differences in teacher retention rates between TTI and comparison teams at the elementary or middle school level. The study authors used a randomized controlled trial design and, therefore, this study could "meet What Works Clearinghouse (WWC) evidence standards without reservations." However, additional information related to the composition of the analysis sample and attrition is needed from the authors before a study rating can be determined. A more thorough review (forthcoming) will determine the rating for the study and report more fully on its results.
