What this school's NCES data tells you
Lake Brantley High School reports 2,813 enrolled students to the National Center for Education Statistics (NCES) alongside 109.0 full-time-equivalent teachers, producing a 24.9:1 student-teacher ratio. That figure sits 36% above the Florida state mean of 18.3:1, signalling larger average class loads than peers in the same state. Against the national 2024-25 average of 15.9:1, it is 57% higher, a useful calibration for families comparing districts across state lines.
Title I and federal lunch eligibility offer another window into the student body: 36.1% of pupils qualify for free meals, a proxy for household income that federal programs use to direct funding. The free-lunch share is 31% below the Florida average and 30% below the national baseline. The school offers 32 Advanced Placement courses, a stronger academic pipeline indicator than enrollment alone. Counselor coverage works out to roughly 563 students per counselor, above the ASCA-recommended ceiling of 250:1. Chronic absenteeism — missing 10% or more of school days — stands at 33.6% according to the 2021-22 Civil Rights Data Collection.
On the finance side, the surrounding Seminole spends $10,225 per pupil district-wide, below the Florida average of $12,756 and below the national average of $19,490.

Taken together, these measurements produce a Resource Investment Index of 37/100 (F), calculated from 5 distinct NCES and CRDC indicators measuring resource allocation rather than academic outcomes.
