Washington State Teacher Demographics and Experience Metrics

Eight school years of teacher demographic and experience data from Washington State's Report Card system, covering the 2017-18 through 2024-25 periods. The dataset provides counts, percentages, and average experience metrics disaggregated by state, educational service district, local education agency, and school levels. It is published by the Washington Office of Superintendent of Public Instruction via data.wa.gov.
