What this school's NCES data tells you
Castle High School reports 1,953 enrolled students to the National Center for Education Statistics (NCES) alongside 104.0 full-time-equivalent teachers, producing a 18.9:1 student-teacher ratio. That figure sits 17% above the Indiana state mean of 16.1:1, signalling larger average class loads than peers in the same state. Against the national 2024-25 average of 15.9:1, it is 19% higher, a useful calibration for families comparing districts across state lines.
Title I and federal lunch eligibility offer another window into the student body: 21.6% of pupils qualify for free meals, a proxy for household income that federal programs use to direct funding. The free-lunch share is 56% below the Indiana average and 58% below the national baseline. The school offers 17 Advanced Placement courses, a stronger academic pipeline indicator than enrollment alone. Counselor coverage works out to roughly 326 students per counselor, above the ASCA-recommended ceiling of 250:1. Chronic absenteeism — missing 10% or more of school days — stands at 18.3% according to the 2021-22 Civil Rights Data Collection.
On the finance side, the surrounding Warrick County School Corp spends $11,907 per pupil district-wide, below the Indiana average of $14,559 and below the national average of $19,490.
