Abstract
This article summarizes the results of a 2-part study using both state databases and teacher surveys to examine teacher retention and mobility in Washington's teacher workforce. The first part of the research examined individual teacher records during a 5-year period. Statewide analyses were conducted, and 20 districts were selected for in-depth examination. Data were examined in relation to student demographics, measures of student learning, and poverty level of the school, with special attention given to novice teachers and teachers of color. The second part of the study surveyed a representative sample of teachers regarding their views on factors that influence their decisions to stay or leave their school or school district. Findings suggest that focusing on the nature of teacher mobility within a district is a useful way to examine a number of equity concerns.
