This brief examines the mobility of public school teachers and principals (including assistant principals) in Wisconsin and presents annual and five-year mobility rates between 2006/07 and 2010/11. An average of 8.0 percent of teachers changed schools between consecutive years, and 19.4 percent changed schools within a five-year span. Teachers were more likely to move to another school if they had less teaching experience, were in an urban school, or taught in a school with lower academic performance, fewer students, or more economically disadvantaged students. For principals the annual mobility rate averaged 11.9 percent, and the five-year mobility rate was 30.0 percent. Principals were more likely to move to another school if they had less experience or were in an urban school or a school with lower academic performance.
