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 test-score grades or opaque ratings, only official data and transparent indexes you can audit.
95K+ US public schools: raw demographics, resource equity (staffing/AP/discipline), funding data from US Dept of Ed; transparent, auditable resource indexes, no opaque test-score ratings.
The national picture, in one line
The country's 49.0M public-school students attend campuses that look nothing alike: the average district spends $16.6K per pupil and the typical class runs 15.6:1, but funding, staffing, and attendance swing sharply from one state and ZIP code to the next.
Federal data only, NCES Common Core of Data (2024-25), Civil Rights Data Collection (2021-22), and the NCES F-33 finance survey. The figures behind that gap are below.
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 one opaque, test-score-driven grade. PlainSchools instead 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. Any index we publish is built only from these official inputs and fully documented in our methodology.

Serving 49.0M students nationally. The top 10 states alone host roughly half of all schools, reflecting how state population concentration shapes K-12 footprint.

Public School Diversity by State
How racially and ethnically mixed are public schools? A Simpson diversity index averaged by state, from Hawaii at the top to the most homogeneous states, from federal NCES data.
Per-Pupil Spending by State
How much do US public schools spend per student? Enrollment-weighted current per-pupil spending by state, from the high-spending Northeast to the lowest-spending states, from the federal F-33 finance survey.
Gifted Program Access by State
Who offers gifted and talented programs: the share of schools with a gifted program, a divide set largely by state policy, from federal Civil Rights Data Collection figures.
Out-of-School Suspension Rate by State
How often schools remove students from class: out-of-school suspensions per 100 students, a roughly fourfold spread across states, from federal Civil Rights Data Collection figures.
Charter School Enrollment Share by State
Where charters are biggest: from 45% of students in the District of Columbia to zero in states with no charter law, weighted by enrollment from federal NCES data.
Chronic Absenteeism by State
The post-pandemic attendance crisis: in 2021-22 about 1 in 3 students was chronically absent, roughly double the pre-pandemic norm.
Students per School Counselor by State
Where the US falls short of the ASCA-recommended 250:1: 47 of 51 state systems exceed it, from federal CRDC data.
AP Course Access by State
Mapping the "AP deserts": about 1 in 3 US public high schools offers no Advanced Placement course at all.
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 student-teacher ratios 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 student-teacher ratios 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.
21,338 schools - about 24.8% of those reporting, sit above 40% chronic absenteeism.
Share of reporting schools above the 40% severe-absenteeism line.
