Reading the San Antonio numbers
What the 2021-22 NCES and FY2020 Census finance numbers say about this district.
Spending of $17,559 per pupil sits close to the $17,320 metro median — within 1 percent of it, so budget is not what sets this district apart. Only 41 cents of each dollar ($7,166 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.
Funding is split roughly evenly — 45.6% local, 34.4% state — so both the local tax base and the TX aid formula matter to what this district can spend. Federal dollars are an outsized 20% of revenue, a share that tracks concentrated student poverty (Title I) and special-education enrollment.
45,255 students across 98 schools averages 462 students per building, and the district is larger than the typical district covered here (44,998 students). The 14.7:1 student-to-teacher ratio is ordinary for this set of districts (median 15.2:1). It counts all FTE teachers district-wide, so actual class sizes run higher.
Worth flagging: a federal share this large means the district is exposed to grant cycles. Title I and pandemic-era relief awards can move the per-pupil figure between survey years without any change in local taxation.
What this data covers
Read this before comparing districts.
Figures cover San Antonio Isd (LEAID 4838730) as one unit, not any single school in San Antonio. 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.
