Decades of research underscore how important teachers are in students' lives. They are, in fact, one of the most important factors contributing to student success in the classroom. Teachers, particularly highly qualified and effective teachers, are a key ingredient in achieving student success. However, as with many aspects of education, years of research show that access to highly qualified and effective teachers is uneven, at best. For this reason, teacher shortages make up one important component of opportunity gaps, and in turn achievement gaps. These gaps result in discrepancies in reading and math proficiency based on factors including race and socioeconomic status. In Michigan, such opportunity gaps for students who have long lacked access to strong educational resources -- Black and Latino students and children from low-income backgrounds across the entire state -- are deep and persistent. It is with this context that EdTrust-Midwest sought to examine Michigan's educator landscape to determine whether all students have similar access to experienced, credentialed, highly qualified and effective teachers. EdTrust-Midwest spent two years reviewing research, conducting focus groups across geographic regions, and securing, examining and analyzing hard-to-access public and non-public data. The findings paint a troubling picture across Michigan's classrooms, demonstrating how Black and Latino students and students from low-income backgrounds have far less access to credentialed, highly qualified teachers, experience far greater teacher mobility, and have access to far fewer experienced teachers than their white peers. Given how important teacher quality is to student success, it is especially troubling that Black and Latino students, students from low-income backgrounds, and students living in rural and urban areas systematically do not have equitable access to teachers who are likely to be well-prepared and effective in the classroom. These inequities contribute to the devastating and persistent opportunity and achievement gaps for Michigan children and their public schools. The research and findings are presented in this comprehensive report. [Additional support for this report was received from Battle Creek Public Schools, KConnect, and Urban Core Collective.]
