Summary

Julius Cordes Elementary is a K–8 school serving 877 students in Mountain House, California, in the Lammersville Joint Unified district. Its strongest takeaway for families is its standout academic performance: in 2025–2026, it led nearby schools in English language arts and math proficiency and scored above both its district and the state in all three tested subjects.

Math is its clearest strength: proficiency was 89%, 18 percentage points above the district and 51 points above California. ELA proficiency was 88%—11 points above the district and 39 above the state—while science was 79%, 11 points above the district and 43 above the state. Among seven nearby schools in the same district, Julius Cordes had the highest ELA and math results, exceeding their averages by 16 and 23 points, respectively. It ranked third in science, behind Hansen Elementary and Evelyn Costa Elementary; science is its less dominant local subject, though its results remain well above district and state levels.

Results have risen since 2022–2023: ELA increased from 78% to 88%, math from 82% to 89%, and science from 61% to 79%, although science fell from 84% in 2024–2025. The state gaps widened over that period in all three subjects. SchoolDigger ranked Julius Cordes 51st of 5,804 California schools, in the 99th percentile, with 5 stars for 2025–2026. Its 25.3 students per teacher in 2024–2025 was the highest reported ratio among nearby schools, compared with their average of 21.1. The school’s free/reduced lunch eligible share was 3% in 2024–2025; California is identified in the data as a statewide free-meals state, so this figure should be read in that context. SchoolDigger’s statewide ranking for how well the school serves Asian students was at the 82nd percentile, notably below its 99th-percentile overall ranking but still high statewide.
