What this school's NCES data tells you
Sumner Elementary reports 444 enrolled students to the National Center for Education Statistics (NCES) alongside 19.0 full-time-equivalent teachers, producing a 22.5:1 student-teacher ratio. That figure sits 4% 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 42% higher, a useful calibration for families comparing districts across state lines.
Title I and federal lunch eligibility offer another window into the student body: 36.7% of pupils qualify for free meals, a proxy for household income that federal programs use to direct funding. The free-lunch share is 34% below the California average and 29% below the national baseline. Chronic absenteeism — missing 10% or more of school days — stands at 37.6% according to the 2021-22 Civil Rights Data Collection.
On the finance side, the surrounding Claremont Unified spends $16,224 per pupil district-wide, below the California average of $18,039 and below the national average of $19,490. Revenue comes 34.1% from local sources (property taxes), 59.3% from the state, and 6.6% from federal programs per the NCES F-33 finance survey. Taken together, these measurements produce a Resource Investment Index of 15/100 (F), calculated from 3 distinct NCES and CRDC indicators measuring resource allocation rather than academic outcomes.
