Summary:
ZIP code 53555 is home to a single public high school: Lodi High, which serves grades 9–12 with 444 students as part of the Lodi School District. Because there is only one high school in the area, families here have a straightforward choice — and the data shows that school performing well above the state average on nearly every reported measure.
Lodi High's statewide standing has climbed steadily. It ranked 73rd of 431 high schools in 2023–2024, 53rd of 431 in 2024–2025, and 38th of 533 in 2025–2026 — the 93rd percentile, earning 5 stars and placing it in the top 7% of reported high schools. The district overall is listed at the 84th percentile with 4 stars, so the high school sits above the district's overall standing. Test scores back up that trend. In 2025–2026, math proficiency was 68.82% versus 42.93% statewide — the strongest subject and the largest gap over the state. English Language Arts came in at 67.74% versus 48.47%, social studies at 67.31% versus 48.25%, and science at 56.99% versus 43.20%. Every subject beat the state average in both reported years. ELA showed the biggest improvement, rising 9.64 points from the prior year, while math and social studies slipped slightly but remained far above state levels. Science was the lowest of the four subjects, though still comfortably ahead of the state.
Student outcomes are equally strong: a 98.2% graduation rate (state: 92.0%), a 0.2% dropout rate (state: 1.1%), and 6.7% chronic absenteeism (state: 17.3%), though absenteeism runs slightly above the district's 5.0%. For context, 14.86% of students qualify for free or reduced lunch, per-student spending is $18,276, and the student-teacher ratio is 12.1:1; no state benchmarks were provided for these three measures.
