Every public school in America, in plain data
NCES Common Core of Data for every public school in 50 states + DC — enrollment, demographics, chronic absenteeism, free/reduced lunch. No ratings, no opinions. Just data.
95K+ US public schools: raw demographics, resource equity (staffing/AP/discipline), funding data from US Dept of Ed, no ratings.
The equity lens · what the ratings sites don't show
The numbers families actually need — straight from federal records
Most school sites reduce a school to a single grade. We don't. PlainSchools surfaces the resource-equity and funding data the U.S. Department of Education collects but rating sites bury — chronic absenteeism, per-pupil spending, and poverty indicators — for all 95,891 public schools. No scores. No opinions. Just the federal record.

By the numbers · the current federal cycle
The national snapshot, in plain view
One cycle of the federal record, read straight off the data we publish for every school — how class sizes are distributed, what kinds of schools make up the system, and where the attendance crisis actually sits. No index, no grade — the counts themselves.
How class sizes are distributed
Most schools that report staffing land in the 12 – 16:1 band. Counts are schools with a valid NCES student–teacher ratio.
U.S. public schools by student–teacher ratio band, current cycle.
What kinds of schools make up the system
The K-12 universe is more than elementary and high schools — “other / combined” covers K-8, K-12, and ungraded settings that don’t fit one band.
U.S. public schools by reported school level.
The attendance crisis, by the numbers
Chronic absenteeism — missing 15+ days a year — is one of the strongest predictors of outcomes, and the rating sites bury it.
24,275 schools — about 27.3% of those reporting — sit above 40% chronic absenteeism.
Share of reporting schools above the 40% severe-absenteeism line.
