Reading the Phoenix numbers
What the 2021-22 NCES and FY2020 Census finance numbers say about this district.
$14,791 per pupil is 15% below the $17,320 metro median; only 32% of tracked districts spend less. Only 40 cents of each dollar ($5,969 per student) is classified as instruction, so a large share goes to support services, facilities and transport — common in districts with long bus routes or older buildings.
Money is raised locally: 64.1% of revenue comes from local sources — overwhelmingly property tax — against 23% from the state. That makes the district's budget move with Phoenix property values and levy votes rather than with the AZ legislature. Federal aid contributes 12.9%, near the typical share for a large urban district.
27,900 students across 19 schools averages 1,468 students per building, and the district is smaller than the typical district covered here (44,998 students). Buildings that size skew secondary — large comprehensive high schools pull the average up. Staffing is thin relative to peers: 19.3 students per FTE teacher against a 15.2 median, 4.1 students more per teacher.
What this data covers
Read this before comparing districts.
Figures cover Phoenix Union High School District (4286) (LEAID 0406330) as one unit, not any single school in Phoenix. Independently authorised charter schools, private schools and regional vocational programs are counted separately by NCES and are not in these totals. Enrollment is the 2021-22 NCES collection; dollars are the FY2020 Census F-33 survey, the latest complete national release. The two years differ, so per-pupil spending is a stable indicator rather than a live budget line.
