What this school's NCES data tells you
Key El reports 391 enrolled students to the National Center for Education Statistics (NCES) alongside 29.0 full-time-equivalent teachers, producing a 13.8:1 student-teacher ratio. That figure sits 5% below the Texas state mean of 14.6:1, signalling more teacher attention per pupil than the state benchmark. Against the national 2024-25 average of 15.7:1, it is 12% lower, a useful calibration for families comparing districts across state lines.
Title I and federal lunch eligibility offer another window into the student body: 70.3% of pupils qualify for free meals, a proxy for household income that federal programs use to direct funding. The free-lunch share is 14% above the Texas average and 36% above the national baseline. Counselor coverage works out to roughly 391 students per counselor, above the ASCA-recommended ceiling of 250:1. Chronic absenteeism — missing 10% or more of school days — stands at 33.8% according to the 2021-22 Civil Rights Data Collection.
On the finance side, the surrounding Arlington Isd spends $11,489 per pupil district-wide, below the Texas average of $13,644 and below the national average of $16,593.

Taken together, these measurements produce a Resource Investment Index of 38/100 (F), calculated from 4 distinct NCES and CRDC indicators measuring resource allocation rather than academic outcomes.
