What this school's NCES data tells you
Grizzly Challenge Charter reports 241 enrolled students to the National Center for Education Statistics (NCES) alongside 13.0 full-time-equivalent teachers, producing a 16.3:1 student-teacher ratio. That figure sits 25% below the California state mean of 21.6:1, signalling more teacher attention per pupil than the state benchmark. Against the national 2024-25 average of 15.9:1, it is 3% higher, a useful calibration for families comparing districts across state lines.
Title I and federal lunch eligibility offer another window into the student body: 69.3% of pupils qualify for free meals, a proxy for household income that federal programs use to direct funding. The free-lunch share is 25% above the California average and 34% above the national baseline. Counselor coverage works out to roughly 121 students per counselor, meeting the American School Counselor Association recommendation of 250:1. Chronic absenteeism — missing 10% or more of school days — stands at 12.9% according to the 2021-22 Civil Rights Data Collection.
Taken together, these measurements produce a Resource Investment Index of 44/100 (D), calculated from 5 distinct NCES and CRDC indicators measuring resource allocation rather than academic outcomes.
