Teacher turnover has an impact on all stakeholders in the school environment, and research shows that students struggle to perform well in schools with turnover year after year. Retaining effective staff can be a big challenge for schools and districts, as can figuring out how to solve the issues around this problem.
In “Using Data to Combat Attrition and Keep Good Teachers,” Henry Wellington, CEO and founder of Upbeat, discussed issues that cause teacher turnover and how schools and districts can intervene. Although 30 percent of teachers leave for reasons outside of schools’ control, the other 70 percent are leaving due to issues that occur within the school environment, and lack of data makes it difficult to find out why.
