What this school's NCES data tells you
Mountain Middle School reports 302 enrolled students to the National Center for Education Statistics (NCES) alongside 14.0 full-time-equivalent teachers, producing a 21.5:1 student-teacher ratio. That figure sits 27% above the Colorado state mean of 16.9:1, signalling larger average class loads than peers in the same state. Against the national 2024-25 average of 15.9:1, it is 35% higher, a useful calibration for families comparing districts across state lines.
Counselor coverage works out to roughly 355 students per counselor, above the ASCA-recommended ceiling of 250:1. Chronic absenteeism — missing 10% or more of school days — stands at 3.3% according to the 2021-22 Civil Rights Data Collection.
On the finance side, the surrounding State Charter School Institute spends $12,972 per pupil district-wide, below the Colorado average of $20,949 and below the national average of $19,490. Revenue comes 8.8% from local sources (property taxes), 81.0% from the state, and 10.1% from federal programs per the NCES F-33 finance survey. Taken together, these measurements produce a Resource Investment Index of 51/100 (C-), calculated from 4 distinct NCES and CRDC indicators measuring resource allocation rather than academic outcomes.
