These files are the product of the Common Core of Data (CCD) data collection for the 2021–22 school year. Data are reported at state, district, and school levels and include staff counts by professional category, as well as student membership disaggregated by grade, race/ethnicity, and sex. Also included are school-level counts of students eligible for free and reduced-price lunch. Along with the data files, four web tables summarizing select CCD indicators are also available.
