Viral Change: Trends in Michigan Teacher Attrition and Mobility before and during the COVID-19 Pandemic. Policy Brief

Educators and policymakers across the country have been raising alarms about a growing teacher shortage. In Michigan, teacher shortages were so severe in the 2018-19 school year that 2,500 classrooms were staffed by long-term substitutes --nearly ten times the number placed in classrooms five years prior. The COVID-19 pandemic has raised even greater concerns about the supply of teachers, with several surveys of Michigan educators administered early in the COVID-19 pandemic indicating a substantial proportion of full-time and substitute teachers considering leaving the teaching profession as a result of pandemic-related concerns. In this study, we use administrative data from Michigan to understand how teachers' propensities to leave the public school system, switch districts, or switch schools shifted after the onset of the COVID-19 pandemic.
