Arizona Public School Statistics
Statewide totals for Arizona public schools from the NCES Common Core of Data: enrollment and staffing for the 2023–24 school year, finance for fiscal year 2024, and the state’s largest districts.
Arizona reported 1,117,630 public school students in the 2023–24 school year, attending 2,399 public schools run by 676 local education agencies with enrolled students. Enrollment is the denominator behind almost every other statistic on this page: it drives the student–teacher ratio, frames the diploma count, and — through state funding formulas — shapes the revenue totals reported in the finance files. Because the CCD is a census of state administrative records rather than a sample survey, these totals are the official counts states themselves submitted to the federal government, with the school year printed next to each figure.

The finance rows are labeled FY2024 because the National Public Education Financial Survey reports by fiscal year; fiscal year 2024 is the finance counterpart of the 2023–24 school year. The membership and staffing rows come from the 2023–24 CCD state files. Keeping those labels attached is deliberate — see why the years differ across files.
Staffing statewide
Arizona schools employed 49,260 full-time-equivalent classroom teachers in 2023–24, a student–teacher ratio of 22.7 to 1. That ratio is an average across very different settings — small rural schools, large suburban campuses and specialized programs all blend into one number — so it is best used to compare states in the same year, or one state across years, rather than to predict any individual classroom. District-level ratios for the state’s largest districts are on their district pages, linked in the table below.
Spending and revenue
The NPEFS file reports $13,366,112,140 in total current expenditures and $16,683,572,155 in total revenues for Arizona public schools in fiscal year 2024, with a published per-pupil current expenditure of $13,113. NPEFS per-pupil figures are computed by NCES from current expenditures and fall membership in the finance collection; they are the standard source for state-to-state spending comparisons because every state reports through the same accounting handbook. District-level spending, where the F-33 file supports it, appears on individual district pages and can differ sharply from the state average in both directions.
Completions
Public schools in Arizona awarded 79,746 regular secondary school diplomas in 2023–24, per the CCD Completers file. A diploma count is a flow of credentials in one year, not a graduation rate; the federal cohort graduation rate is produced separately by EDFacts from tracked ninth-grade cohorts. We publish the count, labeled as a count, and explain the distinction on our measurement methodology page.
