What this school's NCES data tells you
San Mateo Elementary School reports 520 enrolled students to the National Center for Education Statistics (NCES) alongside 30.0 full-time-equivalent teachers, producing a 17.8:1 student-teacher ratio. That figure sits 3% below the Florida state mean of 18.3:1, signalling more teacher attention per pupil than the state benchmark. Against the national 2024-25 average of 15.9:1, it is 12% higher, a useful calibration for families comparing districts across state lines.
Title I and federal lunch eligibility offer another window into the student body: 48.1% of pupils qualify for free meals, a proxy for household income that federal programs use to direct funding. The free-lunch share is 7% below the Florida average and 7% below the national baseline. Counselor coverage works out to roughly 520 students per counselor, above the ASCA-recommended ceiling of 250:1. Chronic absenteeism — missing 10% or more of school days — stands at 39.0% according to the 2021-22 Civil Rights Data Collection.
On the finance side, the surrounding Duval spends $11,534 per pupil district-wide, below the Florida average of $12,756 and below the national average of $19,490. Revenue comes 40.9% from local sources (property taxes), 39.3% from the state, and 19.8% from federal programs per the NCES F-33 finance survey. Taken together, these measurements produce a Resource Investment Index of 25/100 (F), calculated from 4 distinct NCES and CRDC indicators measuring resource allocation rather than academic outcomes.
