Districts are ranked by total 2024-25 enrollment reported to the NCES Common Core of Data. Every agency type is included, so a state-run or charter network can appear if it is large enough. Districts with no reported enrollment are left out.

Size is not a measure of quality. Large districts often contain a wide range of schools. Spending per pupil is from the 2020 finance data and is shown for context.

Finance figures are 2020 finance data in nominal dollars, not adjusted for inflation. Blank values are not available, not applicable or suppressed in the source. See the methodology.
