Educator labor markets vary considerably across the country and can change quickly during recessions. We use data from the Quality Workforce Indicators (QWI) on educators in Elementary and Secondary Schools from 2000-01 to 2022-23. We demonstrate how to transform the quarter-level data in the QWI to construct valid educator labor market measures. The strengths of the QWI address the limitations of other sources of labor market data, including (1) non-standardized definitions, (2) sampling that is useful for describing local and regional trends, (3) contemporaneous availability, and (4) lack of data for sub-groups. We demonstrate how the QWI addresses each of these data gaps and describe how educator labor markets vary across time, region, and educator characteristics.
