What this school's NCES data tells you
21st Century Preparatory School reports 438 enrolled students to the National Center for Education Statistics (NCES) alongside 34.0 full-time-equivalent teachers, producing a 15.2:1 student-teacher ratio. That figure sits 1% above the Wisconsin state mean of 15.1:1, signalling larger average class loads than peers in the same state. Against the national 2024-25 average of 15.9:1, it is 4% lower, a useful calibration for families comparing districts across state lines.
Counselor coverage works out to roughly 219 students per counselor, meeting the American School Counselor Association recommendation of 250:1. Chronic absenteeism — missing 10% or more of school days — stands at 73.5% according to the 2021-22 Civil Rights Data Collection.
Taken together, these measurements produce a Resource Investment Index of 31/100 (F), calculated from 4 distinct NCES and CRDC indicators measuring resource allocation rather than academic outcomes.
