Reading the Wilmington numbers
What the 2021-22 NCES and FY2020 Census finance numbers say about this district.
At $20,253 per pupil the district spends 17% more than the $17,320 metro median, outspending 65% of the districts covered. Instruction takes 51 cents of each dollar — $10,300 per student — with the remainder on transport, buildings, food service and administration.
Funding is split roughly evenly — 40.6% local, 51.7% state — so both the local tax base and the DE aid formula matter to what this district can spend. Federal aid is a small 7.7% of the total, so national funding changes have limited effect on this budget.
14,771 students across 28 schools averages 528 students per building, and the district is smaller than the typical district covered here (44,998 students). The 13.5:1 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.
What this data covers
Read this before comparing districts.
Red Clay Consolidated School District is a county-scale district, so its catchment reaches well past the Wilmington city limits and these figures describe that wider area. 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.
