The "Supports Associated with Teacher Retention in Michigan" study examined local teacher retention rates from 2013/14 to 2018/19 and teachers' responses to a survey about teacher supports in their local agencies and their perceptions of those supports. Average annual teacher retention rates among Michigan's local education agencies ranged from 33 percent to 100 percent in the six-year period. The likelihood that teachers would remain teaching in their local education agency was higher in local education agencies that served lower percentages of students who were economically disadvantaged, higher percentages of students who were White, and higher percentages of students proficient in English language arts. Supports associated with teacher retention varied by the type of local education agency and the percentage of students who were economically disadvantaged. Findings from this study can help education agencies in Michigan prioritize which of 30 teacher supports examined merit more rigorous investigation. This document presents the following three appendixes that accompany the study: (1) Methods; (2) Detailed findings; and (3) The Michigan Department of Education's Teacher Survey on Teacher Supports.
