What this school's NCES data tells you

Sonoma Mountain High (Continuation) reports 21 enrolled students to the National Center for Education Statistics (NCES) alongside 1.0 full-time-equivalent teachers, producing a 23:1 student-teacher ratio. That figure sits 6% above the California state mean of 21.6:1, signalling larger average class loads than peers in the same state. Against the national 2024-25 average of 15.9:1, it is 45% higher, a useful calibration for families comparing districts across state lines.

Title I and federal lunch eligibility offer another window into the student body: 52.2% of pupils qualify for free meals, a proxy for household income that federal programs use to direct funding. The free-lunch share is 6% below the California average and 1% above the national baseline. Chronic absenteeism — missing 10% or more of school days — stands at 100.0% according to the 2021-22 Civil Rights Data Collection.

Taken together, these measurements produce a Resource Investment Index of 12/100 (F), calculated from 4 distinct NCES and CRDC indicators measuring resource allocation rather than academic outcomes.
