Summary

Joe Serna Junior Charter is a K–8 school in Acampo with 369 students, part of Lodi Unified, in an area where most nearby schools serve only K–6. Its most important academic pattern is uneven performance: it stands out locally in English and science, while mathematics is a relative weakness.

In 2025–26, about 50% of students were proficient in English language arts (ELA), 41% in science, and 32% in math. ELA and science ranked second among nine nearby schools, and science was about 5 percentage points above the state and 15 above the district; ELA was nearly level with the state and 10 points above the district. Math ranked fourth nearby: it was 2 points above the district but 6 below the state, and only 3 points above the nearby-school average. Attendance is another clear strength: chronic absenteeism was 8% in 2025–26, the lowest among nearby schools and below the state’s 18% and district’s 24%.

Science has improved, rising 8 points from 2022–23 to 2025–26, while ELA fell 2 points and math changed little; over that period, the school’s state advantage in ELA nearly disappeared and its math deficit widened from about 3 to 6 points. SchoolDigger ranked the school 3,024 out of 5,804, at the 48th percentile with 2 stars in 2025–26; its percentile has fallen 19 points since 2021–22. In 2024–25, its student–teacher ratio was 19.3:1, and 73% of students were free/reduced lunch eligible. SchoolDigger’s English Language Learner Students effectiveness ranking was notably high, at the 90th percentile in 2023–24, compared with the school’s overall 59th percentile that year. Its Male Students ranking fell from the 59th percentile in 2023–24 to the 40th in 2025–26. All-grades comparisons have limits because most nearby schools serve fewer grades; grade-level results can offer a more direct comparison.
