Teacher turnover is a perennial concern, especially in low-performing, high-poverty schools. While districts and schools may try to anticipate and mitigate turnover by surveying teachers about their future plans, existing research on whether teacher-reported intent is predictive of actual turnover behavior is mixed. Using unique survey data from teachers in 35 low-performing, high-poverty districts in Michigan linked at the teacher level to statewide administrative data, we are able to measure turnover behavior one, two, and three years following reported intent. We find that intent is a significant predictor of turnover and becomes increasingly predictive over time. We also find organizational commitment and school organizational conditions are important factors in teachers' intent and, to a lesser degree, actual turnover behavior.
