How are California districts handling deepening teacher shortages 18 months into the COVID-19 pandemic? Following up on a March 2021 study, "California Teachers and COVID-19: How the Pandemic Is Impacting the Teacher Workforce" (ED614374), this report describes the severe shortages many districts are experiencing and the strategies some are using to mitigate these shortages. Through a survey of a sample of California superintendents and human resources administrators conducted in August and September 2021, this study investigates the role COVID-19 has had on key aspects of teacher supply and demand, including teacher retirements, resignations, vacancies, and hiring strategies. Leaders from eight of the largest California districts participated in the study. In addition, the study included leaders from four small rural districts because research shows these types of districts often have additional challenges recruiting and retaining teachers. Together, these districts serve nearly 1 in 6 California students.
